Coarsely, the compile-time translator iterates over \verb|op_par_loop| calls in the source code and performs the following operations: + +\begin{itemize} +\item Generates a host stub for the kernel that is called. +\item Generates a wrapper around the OP2 kernel, that, for example, stages data into and out of shared memory. +\item Inserts a call to the original OP2 kernel inline in the generated wrapper, but leaves the kernel untouched. +\end{itemize} + +\noindent The OP2 runtime manages: + +\begin{itemize} +\item Transfer of data to/from the device. +\item Planning parallel execution. +\item Invoking the host stubs for kernels. +\end{itemize} + +The question of which parts of the ROSE-based translator should be used arises. The position outlined in this document is that: + +\begin{itemize} +\item The code that performs the generation of the host stub should be replaced by support in the runtime that calls the plan function and executes the kernel for each colour according to the plan. +\item The plan function from OP2 should be re-used as-is. +\item Since this leaves effectively no source-to-source transformation to perform (only inserting an essentially unmodified kernel into generated code) it should be possible to avoid the use of ROSE altogether. Should transformation need to be performed on OP2 kernels in future, this functionality may be added, either by integrating ROSE or using a simpler framework, since the operations performed in a kernel are limited to a fairly restricted subset of C/CUDA. +\item In order to speed development, maintainability and integration with MCFC and Fluidity, a sensible choice of language for the re-implementation is Python (hence PyOP2). +\end{itemize} + +The remainder of this document describes the PyOP2 API, and how this API may be implemented.

op2 calls It is illegal to call an op2 function before op2.init. To enforce this, the selected backend is initially a void backend that raises a NotImplementedError and reminds the user to call op2.init. The user-facing API now just stubs user-visible calls and delegates to the backend to do all the object creation. A typical class now looks like: class Kernel(object): def __new__(klass, *args): return backend.Kernel(*args) On the backend side, in addition to the void backend, there is a common backend that implements argument checking and defines backend-agnostic stuff (such as access descriptors). To implement a new device-specific backend, classes should derive from this common backend like so: from common import Access, IterationSpace, Set from common import READ, WRITE, RW, INC, MIN, MAX import common class Kernel(common.Kernel): def __init__(self, code, name): common.Kernel.__init__(self, code, name) # extra set-up here def compile(self): # compile kernel for device execution An incomplete example of this is implemented in the cuda backend. --- pyop2/backend.py | 112 -------------- pyop2/backends/__init__.py | 0 pyop2/backends/common.py | 306 +++++++++++++++++++++++++++++++++++++ pyop2/backends/cuda.py | 52 +++++++ pyop2/backends/void.py | 38 +++++ pyop2/op2.py | 304 +++++------------------------------- 6 files changed, 433 insertions(+), 379 deletions(-) delete mode 100644 pyop2/backend.py create mode 100644 pyop2/backends/__init__.py create mode 100644 pyop2/backends/common.py create mode 100644 pyop2/backends/cuda.py create mode 100644 pyop2/backends/void.py diff --git a/pyop2/backend.py b/pyop2/backend.py deleted file mode 100644 index 5b5a2dc135..0000000000 --- a/pyop2/backend.py +++ /dev/null @@ -1,112 +0,0 @@ -import op2 - -class ParLoopCall(object): - """ - Backend Agnostic support code - """ - - def __init__(self, kernel, it_space, *args): - assert ParLoopCall.check(kernel, it_space, *args) - self._kernel = kernel - self._it_space = it_space - self._args = args - - @staticmethod - def check(kernel, it_space, *args): - #TODO - return True - -class Backend(object): - """ - Generic backend interface - """ - - def __init__(self): - raise NotImplementedError() - - def handle_kernel_declaration(self, kernel): - raise NotImplementedError() - - def handle_datacarrier_declaration(self, datacarrier): - raise NotImplementedError() - - def handle_map_declaration(self, map): - raise NotImplementedError() - - def handle_par_loop_call(self, kernel, it_space, *args): - self._handle_par_loop_call(ParLoopCall(kernel, it_space, args)) - - def _handle_par_loop_call(self, parloop): - raise NotImplementedError() - - def handle_datacarrier_retrieve_value(self, datacarrier): - raise NotImplementedError() - -class VoidBackend(Backend): - """ - Checks for valid usage of the interface, - but actually does nothing - """ - - def __init__(self): - pass - - def handle_kernel_declaration(self, kernel): - assert isinstance(kernel, op2.Kernel) - - def handle_datacarrier_declaration(self, datacarrier): - assert isinstance(datacarrier, op2.DataCarrier) - - def handle_map_declaration(self, map): - assert isinstance(map, op2.Map) - - def _handle_par_loop_call(self, parloop): - pass - - def handle_datacarrier_retrieve_value(self, datacarrier): - assert isinstance(datacarrier, op2.DataCarrier) - -class OpenCLBackend(Backend): - """ - Checks for valid usage of the interface, - but actually does nothing - """ - - def __init__(self): - self._ctx = cl.create_some_context() - self._queue = cl.CommandQueue(self._ctx) - self._warpsize = 1 - self._threads_per_block = self._ctx.get_info(cl.context_info.DEVICES)[0].get_info(cl.device_info.MAX_WORK_GROUP_SIZE) - self._blocks_per_grid = 200 - - def handle_kernel_declaration(self, kernel): - assert isinstance(kernel, op2.Kernel) - - def handle_datacarrier_declaration(self, datacarrier): - assert isinstance(datacarrier, op2.DataCarrier) - if (isinstance(datacarrier, op2.Dat)): - buf = cl.Buffer(self._ctx, cl.mem_flags.READ_WRITE, size=datacarrier._data.nbytes) - cl.enqueue_write_buffer(self._queue, buf, datacarrier._data).wait() - self._buffers[datacarrier] = buf - else: - raise NotImplementedError() - - def handle_map_declaration(self, map): - assert isinstance(map, op2.Map) - # dirty how to do that properly ?

The planning functionality is wrapped up in an op_plan cython class. To access the data needed for execution from the plan, use the class methods that correspond to the OP2-Common struct slot name. For example, to get the loc_map slot from an op_plan instance, do: array = plan.loc_map() This returns a 1-D numpy array of the correct type whose data buffer points to the C side's data. That means, DO NOT CHANGE the data you get back from these calls. Python code is responsible for marshalling the relevant bits of plan data to the device if necessary. There is no python object representing a plan, so lots of the glue code is missing. --- pyop2/_op_lib_core.pxd | 44 +++++++++++++++-- pyop2/op_lib_core.pyx | 105 +++++++++++++++++++++++++++++++++++++++-- 2 files changed, 142 insertions(+), 7 deletions(-) diff --git a/pyop2/_op_lib_core.pxd b/pyop2/_op_lib_core.pxd index b76e5b5daa..f4f6f7ec77 100644 --- a/pyop2/_op_lib_core.pxd +++ b/pyop2/_op_lib_core.pxd @@ -3,10 +3,9 @@ Cython header file for OP2 C library """ cdef extern from "op_lib_core.h": ctypedef struct op_set_core: -

This returns the pointer to the C data structure as a uintptr_t (the integer type guaranteed to be able to hold a void *). In the generated code we now pass this cptr property as an argument, convert it to an unsigned long (aka uintptr_t) and then cast it to an op_mat.

Doing it this way we don't need to expose the code and can wrap the logic for figuring out which integrals are contained in the given form and which kernels we therefore want to initialise inside compile_form. Note: this doesn't yet work for multiple subdomains! There is also further optimisation potential: Currently every kernel is initialised with the generated code for all the integrals contained in the form (since that is what FFC spits out). We could separate out the integrals and only use those to initialise the kernels. Update demos for kernels returned by compile_form: Combining the rhs forms in weak_bcs_ffc demo requires passing both coefficients to either par_loop for rhs assembly. This is due the way FFC generates code. --- demo/adv_diff.py | 13 ++++--------- demo/burgers.py | 7 ++----- demo/mass2d_ffc.py | 7 ++----- demo/mass2d_triangle.py | 7 ++----- demo/mass_vector_ffc.py | 6 ++---- demo/weak_bcs_ffc.py | 20 ++++++++------------ pyop2/ffc_interface.py | 20 ++++++++++++++++---- 7 files changed, 36 insertions(+), 44 deletions(-) diff --git a/demo/adv_diff.py b/demo/adv_diff.py index b832d4aece..483695a8a5 100644 --- a/demo/adv_diff.py +++ b/demo/adv_diff.py @@ -86,15 +86,10 @@ # Generate code for mass and rhs assembly. -mass_code = compile_form(M, "mass") -adv_rhs_code = compile_form(adv_rhs, "adv_rhs") -diff_matrix_code = compile_form(diff_matrix, "diff_matrix") -diff_rhs_code = compile_form(diff_rhs, "diff_rhs") -

In the case of data from an external application, PyOP2 neither owns the data nor is that data a string. We can therefore not call setflags(write=True) on arrays wrapping this data (e.g. from Fluidity). Particularly unpleasantly, attempting such a setflags on an array from Fluidity causes a segfault in numpy. To work around these issues, only attempt to set the write flag on data arrays owned by PyOP2.

Instead we use MatMPIAIJSetPreallocation and determine the number of diagonal and off-process non-zero entries beforehand, instead of building a complete CSR structure. We therefore provide separate sparsity building routines: * build_sparsity_pattern_seq builds a full CSR structure for use with mat.createAIJWithArrays and all memory is allocated and managed by PyOP2. The sparsity contains rowptr, colidx, nz and nnz. * build_sparsity_pattern_mpi only determines the non-zeros per row to be passed to mat.createAIJ. The sparsity contains nz, onz, nnz and onnz. The sparsity object provides properties rowptr, colidx, nz, onz, nnz and onnz, which are 0/empty if not set by the sparsity building routine. nz was previously called total_nz, nnz was d_nnz. When building the MPI sparsity, the executed region of the iteration set is the exec size, which in core.op_set semantics is the sum of core size and exec size. --- pyop2/_op_lib_core.pxd | 6 ++-- pyop2/cuda.py | 2 +- pyop2/op_lib_core.pyx | 42 +++++++++++++++------- pyop2/opencl.py | 2 +- pyop2/runtime_base.py | 25 ++++++++----- pyop2/sparsity_utils.cxx | 77 ++++++++++++++++++++++++++++++---------- pyop2/sparsity_utils.h | 13 ++++--- 7 files changed, 119 insertions(+), 48 deletions(-) diff --git a/pyop2/_op_lib_core.pxd b/pyop2/_op_lib_core.pxd index 1f80c8dec5..dc99bb73c2 100644 --- a/pyop2/_op_lib_core.pxd +++ b/pyop2/_op_lib_core.pxd @@ -130,5 +130,7 @@ cdef extern from "mpi.h": cdef void emit_endif '#endif //' () cdef extern from "sparsity_utils.h": - void build_sparsity_pattern ( int, int, int, int, op_map *, op_map *, - int **, int **, int **, int ** ) + void build_sparsity_pattern_seq ( int, int, int, int, op_map *, op_map *, + int **, int **, int **, int * ) + void build_sparsity_pattern_mpi ( int, int, int, int, op_map *, op_map *, + int **, int **, int *, int * ) diff --git a/pyop2/cuda.py b/pyop2/cuda.py index 1bef5b3a7f..3d899ea158 100644 --- a/pyop2/cuda.py +++ b/pyop2/cuda.py @@ -218,7 +218,7 @@ def _colidx(self): def _csrdata(self): if not hasattr(self, '__csrdata'): setattr(self, '__csrdata', - gpuarray.zeros(shape=self._sparsity.total_nz, + gpuarray.zeros(shape=self._sparsity.nz, dtype=self.dtype)) return getattr(self, '__csrdata') diff --git a/pyop2/op_lib_core.pyx b/pyop2/op_lib_core.pyx index 0557b3ee5f..f383be6107 100644 --- a/pyop2/op_lib_core.pyx +++ b/pyop2/op_lib_core.pyx @@ -96,6 +96,7 @@ Cleanup of C level datastructures is currently not handled. from libc.stdlib cimport malloc, free from libc.stdint cimport uintptr_t +from cpython cimport bool import base import numpy as np cimport numpy as np @@ -540,7 +541,7 @@ def free_sparsity(object sparsity): except: pass -def build_sparsity(object sparsity): +def build_sparsity(object sparsity, bool parallel): cdef int rmult, cmult rmult, cmult = sparsity._dims cdef int nrows = sparsity._nrows @@ -548,6 +549,7 @@ def build_sparsity(object sparsity): cdef op_map rmap, cmap cdef int nmaps = len(sparsity._rmaps) cdef int *d_nnz, *o_nnz, *rowptr, *colidx + cdef int d_nz, o_nz cdef core.op_map *rmaps = malloc(nmaps * sizeof(core.op_map)) if rmaps is NULL: @@ -563,18 +565,32 @@ def build_sparsity(object sparsity): rmaps[i] = rmap._handle cmaps[i] = cmap._handle - core.build_sparsity_pattern(rmult, cmult, nrows, nmaps, - rmaps, cmaps, - &d_nnz, &o_nnz, &rowptr, &colidx) - sparsity._d_nnz = data_to_numpy_array_with_spec(d_nnz, lsize, - np.NPY_INT32) - sparsity._o_nnz = data_to_numpy_array_with_spec(o_nnz, lsize, - np.NPY_INT32) - sparsity._rowptr = data_to_numpy_array_with_spec(rowptr, lsize+1, - np.NPY_INT32) - sparsity._colidx = data_to_numpy_array_with_spec(colidx, - rowptr[lsize], - np.NPY_INT32) + if parallel: + core.build_sparsity_pattern_mpi(rmult, cmult, nrows, nmaps, + rmaps, cmaps, &d_nnz, &o_nnz, + &d_nz, &o_nz) + sparsity._d_nnz = data_to_numpy_array_with_spec(d_nnz, lsize, + np.NPY_INT32) + sparsity._o_nnz = data_to_numpy_array_with_spec(o_nnz, lsize, + np.NPY_INT32) + sparsity._rowptr = [] + sparsity._colidx = [] + sparsity._d_nz = d_nz + sparsity._o_nz = o_nz + else: + core.build_sparsity_pattern_seq(rmult, cmult, nrows, nmaps, + rmaps, cmaps, + &d_nnz, &rowptr, &colidx, &d_nz) + sparsity._d_nnz = data_to_numpy_array_with_spec(d_nnz, lsize, + np.NPY_INT32) + sparsity._o_nnz = [] + sparsity._rowptr = data_to_numpy_array_with_spec(rowptr, lsize+1, + np.NPY_INT32) + sparsity._colidx = data_to_numpy_array_with_spec(colidx, + rowptr[lsize], + np.NPY_INT32) + sparsity._d_nz = d_nz + sparsity._o_nz = 0 finally: free(rmaps) free(cmaps) diff --git a/pyop2/opencl.py b/pyop2/opencl.py index 31ce2a462e..7f52a6d709 100644 --- a/pyop2/opencl.py +++ b/pyop2/opencl.py @@ -233,7 +233,7 @@ def _dev_array(self): if not hasattr(self, '__dev_array'): setattr(self, '__dev_array', array.empty(_queue, - self.sparsity.total_nz, + self.sparsity.nz, self.dtype)) return getattr(self, '__dev_array') diff --git a/pyop2/runtime_base.py b/pyop2/runtime_base.py index 05fc978b39..9069d97533 100644 --- a/pyop2/runtime_base.py +++ b/pyop2/runtime_base.py @@ -343,8 +343,7 @@ def __init__(self, maps, dims, name=None): super(Sparsity, self).__init__(maps, dims, name) key = (maps, as_tuple(dims, int, 2)) self._cached = True - core.build_sparsity(self) - self._total_nz = self._rowptr[-1] + core.build_sparsity(self, parallel=PYOP2_COMM.size > 1) _sparsity_cache[key] = self def __del__(self): @@ -359,12 +358,20 @@ def colidx(self): return self._colidx @property - def d_nnz(self): + def nnz(self): return self._d_nnz @property - def total_nz(self): - return int(self._total_nz) + def onnz(self): + return self._o_nnz + + @property + def nz(self): + return int(self._d_nz) + + @property + def onz(self): + return int(self._o_nz) class Mat(base.Mat): """OP2 matrix data.

Fix this by wrapping the call to the cuda kernel in an if blocks > 0 instead of continuing the loop. --- pyop2/cuda.py | 37 ++++++++++++++++++------------------- 1 file changed, 18 insertions(+), 19 deletions(-) diff --git a/pyop2/cuda.py b/pyop2/cuda.py index c071a52184..7727bbce51 100644 --- a/pyop2/cuda.py +++ b/pyop2/cuda.py @@ -765,25 +765,24 @@ def compute(self): pass blocks = self._plan.ncolblk[col] - if blocks <= 0: - continue - - arglist[-1] = np.int32(blocks) - arglist[-7] = np.int32(block_offset) - blocks = np.asscalar(blocks) - # Compute capability < 3 can handle at most 2**16 - 1 - # blocks in any one dimension of the grid. - if blocks >= 2**16: - grid_size = (2**16 - 1, (blocks - 1)/(2**16-1) + 1, 1) - else: - grid_size = (blocks, 1, 1) - - block_size = (128, 1, 1) - shared_size = np.asscalar(self._plan.nsharedCol[col]) - - _stream.synchronize() - self._fun.prepared_async_call(grid_size, block_size, _stream, *arglist, - shared_size=shared_size) + if blocks > 0: + arglist[-1] = np.int32(blocks) + arglist[-7] = np.int32(block_offset) + blocks = np.asscalar(blocks) + # Compute capability < 3 can handle at most 2**16 - 1 + # blocks in any one dimension of the grid. + if blocks >= 2**16: + grid_size = (2**16 - 1, (blocks - 1)/(2**16-1) + 1, 1) + else: + grid_size = (blocks, 1, 1) + + block_size = (128, 1, 1) + shared_size = np.asscalar(self._plan.nsharedCol[col]) + + _stream.synchronize() + self._fun.prepared_async_call(grid_size, block_size, + _stream, *arglist, + shared_size=shared_size) # We've reached the end of elements that should # contribute to a reduction (this is only different From 8e55dfeee780fe5123fc2a77034cf1107d517e2c Mon Sep 17 00:00:00 2001 From: Florian Rathgeber Date: Mon, 4 Mar 2013 11:54:32 +0000 Subject: [PATCH 1059/3357] Require ScientificPython 2.9 (for NumPy 1.7 compatibility) --- README.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/README.md b/README.md index 60643a8760..5cbf4becd2 100644 --- a/README.md +++ b/README.md @@ -240,7 +240,7 @@ pip install \ bzr+http://bazaar.launchpad.net/~florian-rathgeber/ufc/python-setup#egg=ufc_utils \ bzr+http://bazaar.launchpad.net/~ufl-core/ufl/main#egg=ufl \ bzr+http://bazaar.launchpad.net/~fiat-core/fiat/main#egg=fiat \ - https://sourcesup.renater.fr/frs/download.php/2309/ScientificPython-2.8.tar.gz + hg+https://bitbucket.org/khinsen/scientificpython#egg=ScientificPython ``` ## Setting up the environment From b196921b9f793313d05e2619c08466ff1f0dc575 Mon Sep 17 00:00:00 2001 From: Florian Rathgeber Date: Mon, 4 Mar 2013 15:38:56 +0000 Subject: [PATCH 1060/3357] Add function to get the MPI communicator --- pyop2/op2.py | 2 +- pyop2/runtime_base.py | 4 ++++ 2 files changed, 5 insertions(+), 1 deletion(-) diff --git a/pyop2/op2.py b/pyop2/op2.py index 0229e6ded9..30c9ac2304 100644 --- a/pyop2/op2.py +++ b/pyop2/op2.py @@ -40,7 +40,7 @@ import base from base import READ, WRITE, RW, INC, MIN, MAX, IdentityMap, i from base import _empty_parloop_cache, _parloop_cache_size -from runtime_base import _empty_sparsity_cache, set_mpi_communicator +from runtime_base import _empty_sparsity_cache, get_mpi_communicator, set_mpi_communicator from device import _empty_plan_cache, _plan_cache_size from utils import validate_type from exceptions import MatTypeError, DatTypeError diff --git a/pyop2/runtime_base.py b/pyop2/runtime_base.py index 9069d97533..f76d6cad99 100644 --- a/pyop2/runtime_base.py +++ b/pyop2/runtime_base.py @@ -48,6 +48,10 @@ PYOP2_COMM = None +def get_mpi_communicator(): + global PYOP2_COMM + return PYOP2_COMM + def set_mpi_communicator(comm): """Set the MPI communicator for parallel communication.""" global PYOP2_COMM From 0beba751b2633940de93c9a6cde6ce7f8cf24b34 Mon Sep 17 00:00:00 2001 From: Florian Rathgeber Date: Tue, 5 Mar 2013 13:40:19 +0000 Subject: [PATCH 1061/3357] Ignore the non-serializable MPI communicator when pickling Halos --- pyop2/runtime_base.py | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/pyop2/runtime_base.py b/pyop2/runtime_base.py index f76d6cad99..5559a2b78a 100644 --- a/pyop2/runtime_base.py +++ b/pyop2/runtime_base.py @@ -193,6 +193,16 @@ def verify(self, s): "Halo receive from %d is invalid (not in halo elements)" % \ source + def __getstate__(self): + odict = self.__dict__.copy() + del odict['_comm'] + return odict + + def __setstate__(self, dict): + self.__dict__.update(dict) + # FIXME: This will break for custom halo communicators + self._comm = PYOP2_COMM + class Dat(base.Dat): """OP2 vector data.

FFC generated code for UFC targets is meant to include this header file. We have our own version of this header file, pyop2_geometry.h, which defines the functions from ufc_geometry.h as preprocessor macros. This is necessary to get around the pass-by-reference semantics used for the determinant in the generated kernels. It also saves us from having to annotate all these functions with the correct classifiers for CUDA and OpenCL. Unfortnately we can no longer compile kernels with -Werror because FFC kernels compute the Jacobian inverse regardless of whether it is later used or not.

Core +functionality provided includes object version numbers and copy on +write duplicates. + +Each data carrying object is equipped with a version number. This is +incremented every time the value of the object is changed, whether +this is by a :func:`~pyop2.base.par_loop` or through direct user access to a +:attr:`data` attribute. Access to the :attr:`data_ro` read only data attribute does +not increase the version number. + +Data carrying objects are also equipped with a :meth:`duplicate` +method. From a user perspective, this is a deep copy of the original +object. In the case of :class:`~pyop2.base.Dat` objects, this is implemented +as a shallow copy along with a copy on write mechanism which causes +the actual copy to occur if either the original or the copy is +modified. The delayed copy is implemented by immediately creating a +copy :func:`~pyop2.base.par_loop` and, if lazy evaluation is enabled, +enqueing it. This ensures that the dependency trace will cause all +operations on which the copy depends to occur before the +copy. Conversely, the dependency of the copy :class:`~pyop2.base.Dat` on the +copying loop is artificially removed. This prevents the execution of +the copy being triggered when the copy :class:`~pyop2.base.Dat` is +read. Instead, writes to the original and copy :class:`~pyop2.base.Dat` are +intercepted and execution of the copy :func:`~pyop2.base.par_loop` is forced +at that point.""" + from copy import copy as shallow_copy import op2 From 26aeae36c6d4950243abd4be5b5b90dc26d3b9d0 Mon Sep 17 00:00:00 2001 From: David Ham Date: Wed, 5 Mar 2014 16:38:15 +0000 Subject: [PATCH 2003/3357] Cuda fixes Disable copy on write tests for cuda backend.

Each pair of +entries in the row and column maps gives the row and column index of a +non-zero entry in the matrix and therefore the column index is added to the +set of non-zero entries for that particular row. The array of non-zero entries +per row is then determined as the size of the set for each row and its +exclusive scan yields the row pointer array. The column index array is the +concatenation of all the sets. An algorithm for the sequential case is given +below: :: + + for rowmap, colmap in maps: + for e in range(rowmap.from_size): + for i in range(rowmap.arity): + for r in range(rowdim): + row = rowdim * rowmap.values[i + e*rowmap.arity] + r + for d in range(colmap.arity): + for c in range(coldim): + diag[row].insert(coldim * colmap.values[d + e * colmap.arity] + c) + +For the MPI parallel case a minor modification is required, since for each row +a set of diagonal and off-diagonal column indices needs to be built as +described in :ref:`matrix_storage`: :: + + for rowmap, colmap in maps: + for e in range(rowmap.from_size): + for i in range(rowmap.arity): + for r in range(rowdim): + row = rowdim * rowmap.values[i + e*rowmap.arity] + r + if row < nrows * rowdim: + for d in range(colmap.arity): + for c in range(coldim): + col = coldim * (colmap.values[d + e*colmap.arity]) + c + if col < ncols * coldim: + diag[row].insert(col) + else: + odiag[row].insert(col) + .. _PETSc: http://www.mcs.anl.gov/petsc/ .. _petsc4py: http://pythonhosted.org/petsc4py/ .. _MatSetValues: http://www.mcs.anl.gov/petsc/petsc-dev/docs/manualpages/Mat/MatSetValues.html From 48600ddeee5f1f2b05766eb426e3c490d0576cbc Mon Sep 17 00:00:00 2001 From: Florian Rathgeber Date: Sun, 2 Mar 2014 18:34:58 +0000 Subject: [PATCH 2016/3357] Docs: add CSR diagram --- doc/sphinx/source/images/csr.svg | 1770 ++++++++++++++++++++++++++++++ 1 file changed, 1770 insertions(+) create mode 100644 doc/sphinx/source/images/csr.svg diff --git a/doc/sphinx/source/images/csr.svg b/doc/sphinx/source/images/csr.svg new file mode 100644 index 0000000000..b9e736a71c --- /dev/null +++ b/doc/sphinx/source/images/csr.svg @@ -0,0 +1,1770 @@ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + image/svg+xml + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 10 + 3 + 3 + 8 + 9 + 7 + 8 + 7 + 0 + -2 + 8 + 7 + 5 + 9 + 13 + Sparse Matrix + + + + + + + + + + + + + + + + + + + 10 + -2 + 3 + 9 + 7 + 8 + 7 + 3 + 8 + 7 + 5 + 8 + 9 + 13 + Values array + + + + + + + + + + + + + + + + + + + 0 + 4 + 0 + 1 + 1 + 2 + 3 + 0 + 2 + 3 + 4 + 1 + 3 + 4 + Column indices array + + + + + + + + + + + 0 + 2 + 4 + 7 + 11 + 14 + Row pointer array + + From 1b65ea13e3ce3679b593de0aa4ccc34ca2842aee Mon Sep 17 00:00:00 2001 From: Florian Rathgeber Date: Sun, 2 Mar 2014 19:09:46 +0000 Subject: [PATCH 2017/3357] Docs: include CSR diagram --- doc/sphinx/source/linear_algebra.rst | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/doc/sphinx/source/linear_algebra.rst b/doc/sphinx/source/linear_algebra.rst index 88a2714350..e1f7ed3927 100644 --- a/doc/sphinx/source/linear_algebra.rst +++ b/doc/sphinx/source/linear_algebra.rst @@ -33,6 +33,11 @@ including ``row_ptr[i+1]`` in the column index and values arrays.

The optional parameter ``opts`` is not +specified, meaning that no optimizations are requested; this essentially means +that PyOP2 will leave the kernel untouched. ``code`` will be compiled and run +on the user-specified back-end using the default compiler. ``name`` is used +for debugging and for outputing of meaningful information, e.g. run-times. + +Using the Intermediate Representation +------------------------------------- + +Passing in a string of C code is the simplest way of creating a +:class:`~pyop2.Kernel`. Another possibility is to use PyOP2 Intermediate +Representation (IR) objects to express the :class:`~pyop2.Kernel` semantics. + +An Abstract Syntax Tree of the kernel code can be manually built using IR +objects. Since PyOP2 has been primarily thought to be fed by higher layers +of abstractions, rather than by users, no C-to-AST parser is currently provided. +The advantage of providing an AST, instead of C code, is that it enables PyOP2 +to inspect and transform the kernel, which is aimed at achieving performance +portability among different architectures and, more in general, better execution +times. + +Here, we describe how we can use PyOP2 IR objects to build an AST for the +``init`` kernel shown previously. For example, the most basic AST one can come +up with is + +.. code-block:: python + + from op2 import Kernel + from ir.ast_base import * + + ast = FlatBlock("""void init(double* edge_weight) { + for (int i = 0; i < 3; i++) + edge_weight[i] = 0.0; + }""") + kernel = Kernel(ast, "init") + +The :class:`~pyop2.ir.ast_base.FlatBlock` object encapsulates a ''flat'' block +of code, which is not modified by the IR engine. A +:class:`~pyop2.ir.ast_base.FlatBlock` is used to represent (possibly large) +fragments of code for which we are not interested in any kind of +transformations, so it may be particularly useful to speed up code development +when writing, for example, test cases or non-expensive kernels. On the other +hand, time-demanding kernels should be properly represented using a ''real'' +AST. For example, an useful AST for ``init`` could be the following + +.. code-block:: python + + from op2 import Kernel + from ir.ast_base import * + + ast_body = [FlatBlock("...some code can go here..."), + c_for("i", 3, Assign(Symbol("edge_weight", ("i",)), c_sym("0.0")))] + ast = FunDecl("void", "init", + [Decl("double*", c_sym("edge_weight"))], + ast_body) + kernel = Kernel(ast, "init") + +In this example, we first construct the body of the kernel function. We have +an initial :class:`~pyop2.ir.ast_base.FlatBlock` that contains, for instance, +some sort of initializing code. :func:`~pyop2.ir.ast_base.c_for` is a shortcut +for building a :class:`for loop `. It takes an +iteration variable (``i``), the extent of the loop and its body. Multiple +statements in the body can be passed in as a list. +:func:`~pyop2.ir.ast_base.c_sym` is a shortcut for building :class:`symbols +`. You may want to use +:func:`~pyop2.ir.ast_base.c_sym` when the symbol makes no explicit use of +iteration variables. + +We use :class:`~pyop2.ir.ast_base.Symbol` instead of +:func:`~pyop2.ir.ast_base.c_sym`, when ``edge_weight`` accesses a specific +element using the iteration variable ``i``. This is fundamental to allow the +IR engine performing many kind of transformations involving the kernel's +iteration space(s). Finally, the signature of the function is constructed +using the :class:`~pyop2.ir.ast_base.FunDecl`. + +Other examples on how to build ASTs can be found in the tests folder, +particularly looking into ``test_matrices.py`` and +``test_iteration_space_dats.py``. + + +Achieving Performance Portability with the IR +--------------------------------------------- + +One of the key objectives of PyOP2 is obtaining performance portability. +This means that exactly the same program can be executed on a range of +different platforms, and that the PyOP2 engine will strive to get the best +performance out of the chosen platform. PyOP2 allows users to write kernels +by completely abstracting from the underlying machine. This is mainly +achieved in two steps: + +* Given the AST of a kernel, PyOP2 applies a first transformation aimed at + mapping the parallelism inherent to the kernel to that available in the + backend. +* Then, PyOP2 applies optimizations to the sequential code, depending on the + underlying backend. + +To maximize the outcome of the transformation process, it is important that +kernels are written as simple as possible. That is, premature optimizations, +possibly for a specific backend, might be harmful for performance. + +A minimal language, the so-called PyOP2 Kernel Domain-Specific Language, is +used to trigger specific transformations. If we had had a parser from C +code to AST, we would have embedded this DSL in C by means of ``pragmas``. +As we directly build an AST, we achieve the same goal by decorating AST nodes +with specific attributes, added at node creation-time. An overview of the +language follows + +* ``pragma pyop2 itspace``. This is added to :class:`~pyop2.ir.ast_base.For` + nodes (i.e. written on top of for loops). It tells PyOP2 that the following + is a fully-parallel loop, that is all of its iterations can be executed in + parallel without any sort of synchronization. +* ``pragma pyop2 assembly(itvar1, itvar2)``. This is added to a statement node, + to denote that we are performing a local assembly operation along to the + ``itvar1`` and ``itvar2`` dimensions. +* ``pragma pyop2 simd``. This is added on top of the kernel signature. It is + used to suggest PyOP2 to apply simd vectorization along the ParLoop's + iteration set dimension. Such kind of vectorization is also known as + ''inter-kernel vectorization''. This feature is currently not supported + by PyOP2, and will be added only in a future release. + +The ``itspace`` pragma tells PyOP2 how to extract parallelism from the kernel. +Consider again our usual example. To expose a parallel iteration space, one +one must write + +.. code-block:: python + + from op2 import Kernel + + code = """void init(double* edge_weight) { + #pragma pyop2 itspace + for (int i = 0; i < 3; i++) + edge_weight[i] = 0.0; + }""" + kernel = Kernel(code, "init") + +The :func:`~pyop2.ir.ast_base.c_for` shortcut when creating an AST expresses +the same semantics of a for loop decorated with a ``pragma pyop2 itspace``. + +Now, imagine we are executing the ``init`` kernel on a CPU architecture. +Typically we want a single core to execute the entire kernel, because it is +very likely that the kernel's iteration space is small and its working set +fits the L1 cache, and no benefit would be gained by splitting the computation +among distinct cores. On the other end, if the backend is a GPU or an +accelerator, a different execution model might give better performance. +There's a huge amount of parallelism available, for example, in a GPU, so +delegating the execution of an individual iteration (or a chunk of iterations) +to a single thread could pay off. If that is the case, the PyOP2 IR engine +re-structures the kernel code to exploit such parallelism. + +Optimizing kernels on CPUs +-------------------------- + +So far, some effort has been spent on optimizations for CPU platforms. Being a +DSL, PyOP2 provides specific support for those (linear algebra) operations that +are common among unstructured-mesh-based numerical methods. For example, PyOP2 +is capable of aggressively optimizing local assembly codes for applications +based on the Finite Element Method. We therefore distinguish optimizations in +two categories: + +* Generic optimizations, such as data alignment and support for autovectorization. +* Domain-specific optimizations (DSO) + +To trigger DSOs, statements must be decorated using the kernel DSL. For example, +if the kernel computes the local assembly of an element in an unstructured mesh, +then a ``pragma pyop2 assembly(itvar1, itvar2)`` should be added on top of the +corresponding statement. When constructing the AST of a kernel, this can be +simply achieved by + +.. code-block:: python + + from ir.ast_base import * + + s1 = Symbol("X", ("i",)) + s2 = Symbol("Y", ("j",)) + tensor = Symbol("A", ("i", "j")) + pragma = "#pragma pyop2 outerproduct(j,k)" + code = c_for("i", 3, c_for("j", 3, Incr(tensor, Prod(s1, s2), pragma))) + +That, conceptually, corresponds to + +.. code-block:: c + + #pragma pyop2 itspace + for (int i = 0; i < 3; i++) + #pragma pyop2 itspace + for (int j = 0; j < 3; j++) + #pragma pyop2 assembly(i, j) + A[i][j] += X[i]*Y[j] + +Visiting the AST, PyOP2 finds a 2-dimensional iteration space and an assembly +statement. Currently, ``#pragma pyop2 itspace`` is ignored when the backend is +a CPU. The ``#pragma pyop2 assembly(i, j)`` can trigger multiple DSOs. +PyOP2 currently lacks an autotuning system that finds out automatically the +best possible kernel implementation, that is the optimizations that minimize +the kernel run-time. To drive the optimization process, the user (or the +higher layer) can specifiy which optimizations should be applied. Currently, +PyOP2 can automate: + +* Alignment and padding of data structures: for issuing aligned loads and stores. +* Loop trip count adjustment according to padding: useful for autovectorization + when the trip count is not a multiple of the vector length +* Loop-invariant code motion and autovectorization of invariant code: this is + particularly useful since trip counts are typically small, and hoisted code + can still represent a significant proportion of the execution time +* Register tiling for rectangular iteration spaces +* (DSO for pragma assembly): Outer-product vectorization + unroll-and-jam of + outer loops to improve register re-use or to mitigate register pressure + +How to select specific kernel optimizations +------------------------------------------- + +When constructing a :class:`~pyop2.Kernel`, it is possible to specify the set +of optimizations we want PyOP2 to apply. The IR engine will analyse the kernel +AST and will try to apply, incrementally, such optimizations. The PyOP2's FFC +interface, which build a :class:`~pyop2.Kernel` object given an AST provided +by FFC, makes already use of the available optimizations. Here, we take the +emblematic case of the FFC interface and describe how to play with the various +optimizations through a series of examples. + +.. code-block:: python + + ast = ... + opts = {'licm': False, + 'tile': None, + 'ap': False, + 'vect': None} + kernel = Kernel(ast, 'my_kernel', opts) + +In this example, we have an AST ``ast`` and we specify optimizations through +the dictionary ``opts``; then, we build the :class:`~pyop2.Kernel`, passing in +the optional argument ``opts``. No optimizations are enabled here. The +possible options are: + +* ``licm``: Loop-Invariant Code Motion. +* ``tile``: Register Tiling (of rectangular iteration spaces) +* ``ap``: Data alignment, padding. Trip count adjustment. +* ``vect``: SIMD intra-kernel vectorization. + +If we wanted to apply both loop-invariant code motion and data alignment, we +would simply write + +.. code-block:: python + + ast = ... + opts = {'licm': True, + 'ap': True} + kernel = Kernel(ast, 'my_kernel', opts) + +Now, let's assume we know the kernel has a rectangular iteration space. We want +to try register tiling, with a particular tile size. The way to get it is + +.. code-block:: python + + ast = ... + opts = {'tile': (True, 8)} + kernel = Kernel(ast, 'my_kernel', opts) + +In this case, the iteration space is sliced into tiles of size 8x8. If the +iteration space is smaller than the slice, then the transformation is not +applied. By specifying ``-1`` instead of ``8``, we leave PyOP2 free to choose +automatically a certain tile size. + +A fundamental optimization for any PyOP2 kernel is SIMD vectorization. This is +because almost always kernels fit the L1 cache and are likely to be compute- +bound. Backend compilers' AutoVectorization (AV) is therefore an opportunity. +By enforcing data alignment and padding, we can increase the chance AV is +successful. To try AV, one should write + +.. code-block:: python + + import ir.ast_plan as ap + + ast = ... + opts = {'ap': True, + 'vect': (ap.AUTOVECT, -1)} + kernel = Kernel(ast, 'my_kernel', opts) + +The ``vect``'s second parameter (-1) is ignored when AV is requested. +If our kernel is computing an assembly-like operation, then we can ask PyOP2 +to optimize for register locality and register pressure, by resorting to a +different vectorization technique. Early experiments show that this approach +can be particularly useful when the amount of data movement in the assembly +loops is ''significant''. Of course, this depends on kernel parameters (e.g. +size of assembly loop, number and size of arrays involved in the assembly) as +well as on architecture parameters (e.g. size of L1 cache, number of available +registers). This strategy takes the name of *Outer-Product Vectorization* +(OP), and can be activated in the following way (again, we suggest to use it +along with data alignment and padding). + +.. code-block:: python + + import ir.ast_plan as ap + + ast = ... + opts = {'ap': True, + 'vect': (ap.V_OP_UAJ, 1)} + kernel = Kernel(ast, 'my_kernel', opts) + +``UAJ`` in ``V_OP_UAJ`` stands for ``Unroll-and-Jam``. It has been proved that +OP shows a much better performance when used in combination with unrolling the +outer assembly loop and incorporating (''jamming'') the unrolled iterations +within the inner loop. The second parameter, therefore, specifies the unroll- +and-jam factor: the higher it is, the larger is the number of iterations +unrolled. A factor 1 means that no unroll-and-jam is performed. The optimal +factor highly depends on the computational characteristics of the kernel.

The price for this is +maintaining a larger halo, since we also need halo data, the *non-exec halo* +section, to perform the redundant computation.

It contains information +guiding the code generator on how to partition, stage and colour the data for +efficient parallel processing. + +.. _plan-partitioning: + +Partitioning +------------ + +The iteration set is split into a number of equally sized and contiguous +mini-partitions such that the working set of each mini-partition fits into +shared memory or last level cache. This is unrelated to the partitioning +required for MPI as described in :ref:`mpi`. + +.. _plan-renumbering: + +Local Renumbering and Staging +----------------------------- + +While a mini-partition is a contiguous chunk of the iteration set, the +indirectly accessed data it references is not necessarily contiguous. For each +mini-partition and unique :class:`~pyop2.Dat`-:class:`~pyop2.Map` pair, a +mapping from local indices within the partition to global indices is +constructed as the sorted array of unique :class:`~pyop2.Map` indices accessed +by this partition. At the same time, a global-to-local mapping is constructed +as its inverse. + +Data for indirectly accessed :class:`~pyop2.Dat` arguments is staged in shared +device memory as described in :ref:`backends`. For each partition, the +local-to-global mapping indicates where data to be staged in is read from and +the global-to-local mapping gives the location in shared memory data has been +staged at. The amount of shared memory required is computed from the size of +the local-to-global mapping. + +.. _plan-colouring: + +Colouring +--------- + +A two-level colouring is used to avoid race conditions. Partitions are +coloured such that partitions of the same colour can be executed concurrently +and threads executing on a partition in parallel are coloured such that no two +threads indirectly reference the same data. Only :func:`~pyop2.par_loop` +arguments performing an indirect reduction or assembling a matrix require +colouring. Matrices are coloured per row. + +For each element of a :class:`~pyop2.Set` indirectly accessed in a +:func:`~pyop2.par_loop`, a bit vector is used to record which colours +indirectly reference it. To colour each thread within a partition, the +algorithm proceeds as follows: + +1. Loop over all indirectly accessed arguments and collect the colours of all + :class:`~pyop2.Set` elements referenced by the current thread in a bit mask. +2. Choose the next available colour as the colour of the current thread. +3. Loop over all :class:`~pyop2.Set` elements indirectly accessed by the + current thread again and set the new colour in their colour mask. + +Since the bit mask is a 32-bit integer, up to 32 colours can be processed in a +single pass, which is sufficient for most applications.

+Caching in PyOP2 +================ + +PyOP2 makes heavy use of caches to ensure performance is not adversely +affected by too many runtime computations. The caching in PyOP2 takes +a number of forms: + +1. Disk-based caching of generated code + + Since compiling a generated code module may be an expensive + operation, PyOP2 caches the generated code on disk such that + subsequent runs of the same simulation will not have to pay a + compilation cost. + +2. In memory caching of generated code function pointers + + Once code has been generated and loaded into the running PyOP2 + process, we cache the resulting callable function pointer for the + lifetime of the process, such that subsequent calls to the same + generated code are fast. + +3. In memory caching of expensive to build objects + + Some PyOP2 objects, in particular :class:`~pyop2.Sparsity` objects, + can be expensive to construct. Since a sparsity does not change if + it is built again with the same arguments, we only construct the + sparsity once for each unique set of arguments. + +The caching strategies for PyOP2 follow from two axioms: + +1. For PyOP2 :class:`~pyop2.Set`\s and :class:`~pyop2.Map`\s, equality + is identity +2. Caches of generated code should depend on metadata, but not data + +The first axiom implies that two :class:`~pyop2.Set`\s or +:class:`~pyop2.Map`\s compare equal if and only if they are the same +object. The second implies that generated code must be *independent* +of the absolute size of the data the :func:`~pyop2.par_loop` that +generated it executed over. For example, the size of the iteration +set should not be part of the key, but the arity of any maps and size +and type of every data item should be. + +On consequence of these rules is that there are effectively two +separate types of cache in PyOP2, object and class caches, +distinguished by where the cache itself lives. + +Class caches +------------ + +These are used to cache objects that depend on metadata, but not +object instances, such are generated code. They are implemented by +the cacheable class inheriting from :class:`~.Cached`. + +.. note:: + + There is currently no eviction strategy for class caches, should + they grow too large, for example by executing many different parallel + loops, an out of memory error can occur + +Object caches +------------- + +These are used to cache objects that are built on top of +:class:`~pyop2.Set`\s and :class:`~pyop2.Map`\s. They are implemented by the +cacheable class inheriting from :class:`~.ObjectCached` and the +caching instance defining a ``_cache`` attribute. + +The motivation for these caches is that cache key for objects such as +sparsities relies on an identical sparsity being built if the +arguments are identical. So that users of the API do not have to +worry too much about carrying around "temporary" objects forever such +that they will hit caches, PyOP2 builds up a hierarchy of caches of +transient objects on top of the immutable sets and maps. + +So, for example, the user can build and throw away +:class:`~pyop2.DataSet`\s as normal in their code. Internally, however, +these instances are cached on the set they are built on top of. Thus, +in the following snippet, we have that ``ds`` and ``ds2`` are the same +object: + +.. code-block:: python + + s = op2.Set(1) + ds = op2.DataSet(s, 10) + ds2 = op2.DataSet(s, 10) + assert ds is ds2 + +The setup of these caches is such that the lifetime of objects in the +cache is tied to the lifetime of both the caching and the cached +object. In the above example, as long as the user program holds a +reference to one of ``s``, ``ds`` or ``ds2`` all three objects will +remain live. As soon as all references are lost, all three become +candidates for garbage collection. + +.. note:: + + The cache eviction strategy for these caches relies on the Python + garbage collector, and hence on the user not holding onto + references to some of either the cached or the caching objects for + too long. Should the objects on which the caches live persist, an + out of memory error may occur. + +Debugging cache leaks +--------------------- + +To debug potential problems with the cache, PyOP2 can be instructed to +print the size of both object and class caches at program exit. This +can be done by setting the environment variable +``PYOP2_PRINT_CACHE_SIZE`` to 1 before running a PyOP2 program, or +passing the ``print_cache_size`` to :func:`~pyop2.init`. diff --git a/doc/sphinx/source/index.rst b/doc/sphinx/source/index.rst index 0034bb3b23..77a6096c6b 100644 --- a/doc/sphinx/source/index.rst +++ b/doc/sphinx/source/index.rst @@ -21,6 +21,7 @@ Contents: plan mixed mpi + caching user pyop2 From 1a350c4da9f660e8dbc99be7e04e84e831423306 Mon Sep 17 00:00:00 2001 From: Lawrence Mitchell Date: Mon, 7 Apr 2014 15:52:25 +0100 Subject: [PATCH 2193/3357] Fix __le__ for SparsityMaps The iteration region need not be a single value, so check that the iteration region of self is a subset of the iteration region of other. --- pyop2/base.py | 15 +++++++++------ 1 file changed, 9 insertions(+), 6 deletions(-) diff --git a/pyop2/base.py b/pyop2/base.py index e6ece1a498..f6a4dca969 100644 --- a/pyop2/base.py +++ b/pyop2/base.py @@ -2563,7 +2563,7 @@ def iteration_region(self): """Return the iteration region for the current map.

The goal is to remove the tedious and error-prone "update +the embedded version string" step from your release process. Making a new +release should be as easy as recording a new tag in your version-control +system, and maybe making new tarballs. + + +## Quick Install + +* `pip install versioneer` to somewhere to your $PATH +* run `versioneer-installer` in your source tree: this installs `versioneer.py` +* follow the instructions below (also in the `versioneer.py` docstring) + +## Version Identifiers + +Source trees come from a variety of places: + +* a version-control system checkout (mostly used by developers) +* a nightly tarball, produced by build automation +* a snapshot tarball, produced by a web-based VCS browser, like github's + "tarball from tag" feature +* a release tarball, produced by "setup.py sdist", distributed through PyPI + +Within each source tree, the version identifier (either a string or a number, +this tool is format-agnostic) can come from a variety of places: + +* ask the VCS tool itself, e.g. "git describe" (for checkouts), which knows + about recent "tags" and an absolute revision-id +* the name of the directory into which the tarball was unpacked +* an expanded VCS variable ($Id$, etc) +* a `_version.py` created by some earlier build step + +For released software, the version identifier is closely related to a VCS +tag. Some projects use tag names that include more than just the version +string (e.g. "myproject-1.2" instead of just "1.2"), in which case the tool +needs to strip the tag prefix to extract the version identifier. For +unreleased software (between tags), the version identifier should provide +enough information to help developers recreate the same tree, while also +giving them an idea of roughly how old the tree is (after version 1.2, before +version 1.3). Many VCS systems can report a description that captures this, +for example 'git describe --tags --dirty --always' reports things like +"0.7-1-g574ab98-dirty" to indicate that the checkout is one revision past the +0.7 tag, has a unique revision id of "574ab98", and is "dirty" (it has +uncommitted changes. + +The version identifier is used for multiple purposes: + +* to allow the module to self-identify its version: `myproject.__version__` +* to choose a name and prefix for a 'setup.py sdist' tarball + +## Theory of Operation + +Versioneer works by adding a special `_version.py` file into your source +tree, where your `__init__.py` can import it. This `_version.py` knows how to +dynamically ask the VCS tool for version information at import time. However, +when you use "setup.py build" or "setup.py sdist", `_version.py` in the new +copy is replaced by a small static file that contains just the generated +version data. + +`_version.py` also contains `$Revision$` markers, and the installation +process marks `_version.py` to have this marker rewritten with a tag name +during the "git archive" command. As a result, generated tarballs will +contain enough information to get the proper version. + + +## Installation + +First, decide on values for the following configuration variables: + +* `versionfile_source`: + + A project-relative pathname into which the generated version strings should + be written. This is usually a `_version.py` next to your project's main + `__init__.py` file. If your project uses `src/myproject/__init__.py`, this + should be `src/myproject/_version.py`. This file should be checked in to + your VCS as usual: the copy created below by `setup.py versioneer` will + include code that parses expanded VCS keywords in generated tarballs. The + 'build' and 'sdist' commands will replace it with a copy that has just the + calculated version string. + +* `versionfile_build`: + + Like `versionfile_source`, but relative to the build directory instead of + the source directory. These will differ when your setup.py uses + 'package_dir='. If you have `package_dir={'myproject': 'src/myproject'}`, + then you will probably have `versionfile_build='myproject/_version.py'` and + `versionfile_source='src/myproject/_version.py'`. + +* `tag_prefix`: + + a string, like 'PROJECTNAME-', which appears at the start of all VCS tags. + If your tags look like 'myproject-1.2.0', then you should use + tag_prefix='myproject-'. If you use unprefixed tags like '1.2.0', this + should be an empty string. + +* `parentdir_prefix`: + + a string, frequently the same as tag_prefix, which appears at the start of + all unpacked tarball filenames. If your tarball unpacks into + 'myproject-1.2.0', this should be 'myproject-'. + +This tool provides one script, named `versioneer-installer`. That script does +one thing: write a copy of `versioneer.py` into the current directory. + +To versioneer-enable your project: + +* 1: Run `versioneer-installer` to copy `versioneer.py` into the top of your + source tree. + +* 2: add the following lines to the top of your `setup.py`, with the + configuration values you decided earlier: + + import versioneer + versioneer.versionfile_source = 'src/myproject/_version.py' + versioneer.versionfile_build = 'myproject/_version.py' + versioneer.tag_prefix = '' # tags are like 1.2.0 + versioneer.parentdir_prefix = 'myproject-' # dirname like 'myproject-1.2.0' + +* 3: add the following arguments to the setup() call in your setup.py: + + version=versioneer.get_version(), + cmdclass=versioneer.get_cmdclass(), + +* 4: now run `setup.py versioneer`, which will create `_version.py`, and + will modify your `__init__.py` to define `__version__` (by calling a + function from `_version.py`). It will also modify your `MANIFEST.in` to + include both `versioneer.py` and the generated `_version.py` in sdist + tarballs. + +* 5: commit these changes to your VCS. To make sure you won't forget, + `setup.py versioneer` will mark everything it touched for addition. + +## Post-Installation Usage + +Once established, all uses of your tree from a VCS checkout should get the +current version string. All generated tarballs should include an embedded +version string (so users who unpack them will not need a VCS tool installed). + +If you distribute your project through PyPI, then the release process should +boil down to two steps: + +* 1: git tag 1.0 +* 2: python setup.py register sdist upload + +If you distribute it through github (i.e. users use github to generate +tarballs with `git archive`), the process is: + +* 1: git tag 1.0 +* 2: git push; git push --tags + +Currently, all version strings must be based upon a tag. Versioneer will +report "unknown" until your tree has at least one tag in its history. This +restriction will be fixed eventually (see issue #12). + +## Version-String Flavors + +Code which uses Versioneer can learn about its version string at runtime by +importing `_version` from your main `__init__.py` file and running the +`get_versions()` function. From the "outside" (e.g. in `setup.py`), you can +import the top-level `versioneer.py` and run `get_versions()`. + +Both functions return a dictionary with different keys for different flavors +of the version string: + +* `['version']`: condensed tag+distance+shortid+dirty identifier. For git, + this uses the output of `git describe --tags --dirty --always` but strips + the tag_prefix. For example "0.11-2-g1076c97-dirty" indicates that the tree + is like the "1076c97" commit but has uncommitted changes ("-dirty"), and + that this commit is two revisions ("-2-") beyond the "0.11" tag. For + released software (exactly equal to a known tag), the identifier will only + contain the stripped tag, e.g. "0.11". + +* `['full']`: detailed revision identifier. For Git, this is the full SHA1 + commit id, followed by "-dirty" if the tree contains uncommitted changes, + e.g. "1076c978a8d3cfc70f408fe5974aa6c092c949ac-dirty". + +Some variants are more useful than others. Including `full` in a bug report +should allow developers to reconstruct the exact code being tested (or +indicate the presence of local changes that should be shared with the +developers). `version` is suitable for display in an "about" box or a CLI +`--version` output: it can be easily compared against release notes and lists +of bugs fixed in various releases. + +In the future, this will also include a +[PEP-0440](http://legacy.python.org/dev/peps/pep-0440/) -compatible flavor +(e.g. `1.2.post0.dev123`). This loses a lot of information (and has no room +for a hash-based revision id), but is safe to use in a `setup.py` +"`version=`" argument. It also enables tools like *pip* to compare version +strings and evaluate compatibility constraint declarations. + +The `setup.py versioneer` command adds the following text to your +`__init__.py` to place a basic version in `YOURPROJECT.__version__`: + + from ._version import get_versions + __version = get_versions()['version'] + del get_versions + +## Updating Versioneer + +To upgrade your project to a new release of Versioneer, do the following: + +* install the new Versioneer (`pip install -U versioneer` or equivalent) +* re-run `versioneer-installer` in your source tree to replace `versioneer.py` +* edit `setup.py`, if necessary, to include any new configuration settings indicated by the release notes +* re-run `setup.py versioneer` to replace `SRC/_version.py` +* commit any changed files + +## Future Directions + +This tool is designed to make it easily extended to other version-control +systems: all VCS-specific components are in separate directories like +src/git/ . The top-level `versioneer.py` script is assembled from these +components by running make-versioneer.py . In the future, make-versioneer.py +will take a VCS name as an argument, and will construct a version of +`versioneer.py` that is specific to the given VCS. It might also take the +configuration arguments that are currently provided manually during +installation by editing setup.py . Alternatively, it might go the other +direction and include code from all supported VCS systems, reducing the +number of intermediate scripts. + + +## License + +To make Versioneer easier to embed, all its code is hereby released into the +public domain.

Instead, rework the SparsityMap object to a more general DecoratedMap that allows us to attach arbitrary data to a Map, and use it to store both the iteration_region of a Map (for building sparsities) and any implicit boundary conditions that may need to be applied. --- pyop2/base.py | 96 +++++++++++++++++++++++++++++---------- pyop2/op2.py | 2 +- test/unit/test_caching.py | 42 ++++++++++++----- 3 files changed, 104 insertions(+), 36 deletions(-) diff --git a/pyop2/base.py b/pyop2/base.py index 1bd985694c..e7bfc59802 100644 --- a/pyop2/base.py +++ b/pyop2/base.py @@ -2735,10 +2735,17 @@ def split(self): @property def iteration_region(self): """Return the iteration region for the current map.

This reduces the size of the sparsity pattern we compute by a factor of rdim*cdim and allows for more efficient matrix storage and insertion. As a consequence, we no longer create sequential matrices with arrays (these are not supported for PETSc BAIJ matrices). The parallel and sequential code therefore becomes more closely aligned. --- pyop2/host.py | 242 ++++++++++++++++++++++---------------------- pyop2/mat_utils.h | 32 ------ pyop2/openmp.py | 4 - pyop2/petsc_base.py | 43 ++++---- pyop2/sequential.py | 4 -

When switching between insert and add or vice versa we then know to call assembly flushing at the correct point.

Internally the communicators are duplicated using PetscCommDuplicate so that we don't send messages on the user-provided communicator (but rather an internal communicator). --- pyop2/base.py | 65 +++++++++++++++---------- pyop2/caching.py | 68 --------------------------- pyop2/compilation.py | 66 ++++++++++++++++---------- pyop2/cuda.py | 1 + pyop2/host.py | 4 +- pyop2/logger.py | 5 -- pyop2/mpi-compat.h | 14 ++++++ pyop2/mpi.py | 88 +++++++++++++++++----------------- pyop2/op2.py | 8 +--- pyop2/petsc_base.py | 102 +++++++++++++++------------------------- test/unit/test_api.py | 31 ------------ test/unit/test_petsc.py | 5 -- 12 files changed, 181 insertions(+), 276 deletions(-) create mode 100644 pyop2/mpi-compat.h diff --git a/pyop2/base.py b/pyop2/base.py index 72896f9b90..17b9650111 100644 --- a/pyop2/base.py +++ b/pyop2/base.py @@ -51,7 +51,7 @@ from exceptions import * from utils import * from backends import _make_object -from mpi import MPI, _MPI, _check_comm, collective +from mpi import MPI, collective, dup_comm from profiling import timed_region, timed_function from sparsity import build_sparsity from version import __version__ as version @@ -478,7 +478,7 @@ def halo_exchange_end(self, update_inc=False): self._in_flight = False @collective - def reduction_begin(self): + def reduction_begin(self, comm): """Begin reduction for the argument if its access is INC, MIN, or MAX.

This way, data that is only required by the fused loop (and *not* by the base loop), is only loaded from memory if strictly necessary; that is, if a fused iteration still has to be executed. Example: think of a facets loop (the base loop) merged with a cells loop (the fused loop). We iterate over the facets, and then we check whether any of the adjacent cells still have to be executed; if and only if that's the case, the extra data required by these cells is gathered. --- pyop2/fusion.py | 452 ++++++++++++++++++++++++++++++------------------ 1 file changed, 280 insertions(+), 172 deletions(-) diff --git a/pyop2/fusion.py b/pyop2/fusion.py index 53baa85f0f..3f14021765 100644 --- a/pyop2/fusion.py +++ b/pyop2/fusion.py @@ -86,52 +86,112 @@ by lazy evaluation.""" -class Arg(sequential.Arg): - - @staticmethod - def specialize(args, gtl_map, loop_id, use_glb_maps): - """Given an iterator of :class:`sequential.Arg` objects return an iterator - of :class:`fusion.Arg` objects. - - :arg args: either a single :class:`sequential.Arg` object or an iterator - (accepted: list, tuple) of :class:`sequential.Arg` objects. - :arg gtl_map: a dict associating global map names to local map names. - :arg loop_id: the position of the loop using ``args`` in the loop chain - :arg use_glb_maps: shold global or local maps be used when generating code? +class FArg(sequential.Arg): + + """An Arg specialized for kernels and loops subjected to any kind of fusion.""" + + def __init__(self, arg, gather=None, c_index=False): + """Initialize a :class:`FArg`. + + :arg arg: a supertype of :class:`FArg`, from which this Arg is derived. + :arg gather: recognized values: ``postponed``, ``onlymap``.

Nixon-Hill" Date: Fri, 14 May 2021 09:34:33 +0100 Subject: [PATCH 3198/3357] Loopy sprint (#612) * Change requirements on loopy to point at the loopy sprint branch. * Replace lp.register_callable_kernel with lp.merge knl = lp.register_callable_kernel(knl, callee) is now knl = lp.merge([knl, callee]) . Reason given for loopy breaking back-compat: earlier they had a notion of a special "root_kernel" which only permitted one level of nesting loopy kernel calls and that was too restrictive. * Loopy callables: adapt to new API for registering. * Loopy Callables: register callables on a kernel not functions. * name is static property on SolveCallable and INVCallable * Loopy callables: register the callables rather than functions and remove the lookup functions. * Some progress * Loopy callables: Adapt API of with_types. * INVCallable has name "inverse" in loopy rep * Always pass a target when generating loopy kernels, otherwise we cannot merge them with wrapper kernels. * flake8 * Maybe generate call to inner kernel correctly Still doesn't work later. * Revert "Maybe generate call to inner kernel correctly" This reverts commit 009ca19f3fb133d53affeab53cd016c9b55620a9. * Revert "Revert "Maybe generate call to inner kernel correctly"" This reverts commit c85b60e6382b4762076b2744227fa5a6d903b830. * Remove dead code * rep2loopy: get name of callee kernel for matching the args. * Add missing code target * Maybe handle loopy argument access correctly dat.zero still doesn't work * Promote dats with shape (n,) to shape (n, 1) This enables sweeping indices to pick up a direct loop. * Set lang_version on all make_function calls * Fix disjoint arguments to C-string kernels * Resolve review comments * Rename function_args -> kernel_parameters * WIP Match args for all kernels in the callables table besides for LACallables? Why? * Only match args for callables that are CallableKernels. * Pin decorator Decorator version 5 changes the API in ways that break the argument type checking in PyOP2. We're therefore pinning on the version that works. * catch up with numpy type changes * Set within_inames_is_final on instructions * Squash numpy warning * Set strides on GlobalArgs * Caching: produce key for loop Programs. * Check if kernel is a loopy Program. * loopy.program.Program -> loopy.Program * Adapt to loopy interface changes. * Maintain loopy automatic reshaping (was in loopy) Everything in loopycompat.py file was in loopy/transform/callable.py but is removed in https://github.com/inducer/loopy/pull/327. This commit maintains compatibility but should be phased out. * Fix loopy.program -> loopy.translation_unit * dont lint automatic reshaping (was in loopy) * Lint to pass flake8 * Fix loopy automatic reshaping (was in loopy) Changes were copied from an out of date branch by accident. * Fix type case error (recursively) This mirrors https://github.com/inducer/loopy/pull/326 * ?

This was being provided by runtime argument passing, but not by the code generator, which treated map1 and map2 as distinct things. To fix this, create a new PMap wrapper for Map objects in the codegen builder that just know how to index themselves through their permutation. Now we can share the underlying global map data between the two local map accesses. --- pyop2/codegen/builder.py | 86 +++++++++++++++++++++++++--------------- 1 file changed, 55 insertions(+), 31 deletions(-) diff --git a/pyop2/codegen/builder.py b/pyop2/codegen/builder.py index 50d57ca25c..e09db09ab6 100644 --- a/pyop2/codegen/builder.py +++ b/pyop2/codegen/builder.py @@ -30,32 +30,18 @@ class Map(object): __slots__ = ("values", "offset", "interior_horizontal", "variable", "unroll", "layer_bounds", - "prefetch", "permutation") + "prefetch", "_pmap_count") def __init__(self, map_, interior_horizontal, layer_bounds, - values=None, offset=None, unroll=False): + offset=None, unroll=False): self.variable = map_.iterset._extruded and not map_.iterset.constant_layers self.unroll = unroll self.layer_bounds = layer_bounds self.interior_horizontal = interior_horizontal self.prefetch = {} - if values is not None: - raise RuntimeError - self.values = values - if map_.offset is not None: - assert offset is not None - self.offset = offset - return - offset = map_.offset shape = (None, ) + map_.shape[1:] values = Argument(shape, dtype=map_.dtype, pfx="map") - if isinstance(map_, PermutedMap): - self.permutation = NamedLiteral(map_.permutation, parent=values, suffix="permutation") - if offset is not None: - offset = offset[map_.permutation] - else: - self.permutation = None if offset is not None: if len(set(map_.offset)) == 1: offset = Literal(offset[0], casting=True) @@ -64,6 +50,7 @@ def __init__(self, map_, interior_horizontal, layer_bounds, self.values = values self.offset = offset + self._pmap_count = itertools.count() @property def shape(self): @@ -73,7 +60,7 @@ def shape(self): def dtype(self): return self.values.dtype - def indexed(self, multiindex, layer=None): + def indexed(self, multiindex, layer=None, permute=lambda x: x): n, i, f = multiindex if layer is not None and self.offset is not None: #

The code generation component of what PyOP2 does is now user-facing (via the GlobalKernel object).
