An MPI program *must* call MPI_Test or MPI_Wait to complete a non-blocking request -- it's not optional. For performance portability, it's likely a good idea to have some calls to MPI_Test*() periodically. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
