All MTT testing looks good for 1.6.4. There seems to be an MPI dynamics problem when --enable-spare-groups is used, but this does not look like a regression to me.
I put out a final rc, because there was one more minor change to accommodate an MXM API change; it's in the usual place: http://www.open-mpi.org/software/ompi/v1.6/ Unless something disastrous happens, I plan to release this as the final 1.6.4 tomorrow. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
