It's not yet clear that we have a shared memory problem with gcc 4.4.x -- IBM and Cisco have been unable to replicate. > Can you try running this again with -mca btl ^sm? This would be good data. Can you also send exactly how you're configuring and building OMPI? I have built OMPI 1.4.2 with gcc 4.4.1 and 4.5 and have been unable to replicate either the shared memory problem or this problem. :-( That being said, I'm running on an Intel 5580 (Nehalem EP); I do not have any AMD machines to test on. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
