[OMPI users] current release?

Hi, On Feb 21, Jeff Squyres announced Open MPI 1.6.4. However, on the Open MPI home page, 1.6.3 is still indicated as the current release. Going to the download page shows 1.6.4 as the current release, so I think the problem is isolated to the home page. Thanks! -- Best regards, David

Re: [OMPI users] location of ompi libraries

likely that you compiled Open MPI with --enable-static and/or --disable-dlopen. In this case, all of Open MPI's plugins are slurped up into the libraries themselves (e.g., libmpi.so or libmpi.a). That's why everything continues to work properly. On Oct 4, 2010, at 6:58 PM, David Tur
