rocBLAS-2.38.0 for ROCm 4.2.0

Added

• Added option to install script to build only rocBLAS clients with a pre-built rocBLAS library
• Supported gemm ext for unpacked int8 input layout on gfx908 GPUs
  • Added new flags rocblas_gemm_flags::rocblas_gemm_flags_pack_int8x4 to specify if using the packed layout
    • Set the rocblas_gemm_flags_pack_int8x4 when using packed int8x4, this should be always set on GPUs before gfx908.
    • For gfx908 GPUs, unpacked int8 is supported so no need to set this flag.
    • Notice the default flags 0 uses unpacked int8, this somehow changes the behaviour of int8 gemm from ROCm 4.1.0
• Added a query function rocblas_query_int8_layout_flag to get the preferable layout of int8 for gemm by device

Optimizations

• Improved performance of single precision copy, swap, and scal when incx == 1 and incy == 1.
• Improved performance of single precision axpy when incx == 1, incy == 1 and batch_count =< 8192.
• Improved performance of trmm.

Changed

• Change cmake_minimum_required to VERSION 3.16.8

rocBLAS-2.36.0 for ROCm 4.1.0

Added

• Added Numerical checking helper function to detect zero/NaN/Inf in the input and the output vectors of rocBLAS level 1 and 2 functions.
• Added Numerical checking helper function to detect zero/NaN/Inf in the input and the output general matrices of rocBLAS level 2 and 3 functions.

Fixed
Fixed complex unit test bug caused by incorrect caxpy and zaxpy function signatures.
Make functions compliant with Legacy Blas for special values alpha == 0, k == 0, beta == 1, beta == 0.

Optimizations
Improved performance of single precision axpy_batched and axpy_strided_batched: batch_count >= 8192.
