Does that mean that you'll be blocking (effectively) in the communicator destruction function? I *think* that's ok, but I'm not 100% sure... Brian / George / Nathan: can you confirm? I ask because the standard does not specify what is allowed in attribute callback functions -- which, by omission, means that *everything* is allowed, but I don't know how well tested code paths are that invoke arbitrary MPI (PML) functionality inside communicator teardown. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
