NPB parallelization Error

[Premas]

Hi,

When I try to parallelize DC benchmark of NPB (NAS Parallel Benchmark) suite, I get the following error. I have annexed the code file to be parallelized with this thread.

/****** Command used for parallelization ********/

p4a dc.c adc.c extbuild.c rbt.c jobcntl.c -v
DC.tar.gz

Hello, Is computeChecksum a recursive function? Recursivity is not handled by PIPS, and consequently by Par4All. Regards. Béatrice.

Yes .. It is a recursive function. Can we remove the recursion and parse the Par4all for parallelization?

I don't understand what you mean with "parse the Par4all". But removing the recursion in the input code is definitely the way to go. — You are receiving this because you commented.
