:-) I can't say we've tested Open MPI 1.8.x on OS X 10.6.x -- there may well be some kind of weirdness there. Can you try Open MPI 1.6.5? You'll likely need to download the source tarball from www.open-mpi.org and build/install it yourself (e.g., under your $HOME). Open MPI 1.6.x is also old, but it matches the timeframe of OS X 10.6.x. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
