Thanks for the sharing. If that doesn't bother you too much, I would like to know auto-parallelization benchmarks. :p Just curious. I was thinki...

Hello. I am trying to vectorize a CSR SpMV (sparse matrix vector multiplication) procedure but the LLVM loop vectorizer is not able to handle such code. I am using cland and llvm version 3.4 (on Ubuntu 12.10). I use the -fvectorize option with clang and -loop-vectorize with opt-3.4 . The CSR SpMV function is inspired from

Hi all, I am looking appropriate Benchmarking for the assessment of automatic parallelization project.

If it's the latter, I sugguest you find scientific or graphic applications. I don't think there is auto-parallelization benchmark, however. Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer

This is a bug, but I&...
