Subject: [OMPI devel] SSE instructions?
From: Larry Baker (baker_at_[hidden])
Date: 2011-05-18 20:32:00


The PGI compilers have a -fast and a -fastsse option. Does OpenMPI
make effective/safe use of SSE instructions (block moves maybe?)? On
their web site, PGI uses -fast in their examples for OpenMPI rather
than -fastsse. I don't know why.
