Thanks!
Sorry for the latency in reply. I would guess that the Open MPI libraries have been linked against the PGI 10.5 libraries, and it might not be easy to dis-entangle them. It *might* be a simple as changing your LD_LIBRARY_PATH, but it might not. Since there's some question as to how to do it properly, it's probably safest / easiest / least total time spent to just build another copy of OMPI against 10.8. :-\ -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
