I'm not quite sure I understand your question. There currently is no probe for collectives, but MPI-3 has non-blocking collectives which you could MPI_Test for. There's a 3rd party library implementation called libNBC (non-blocking collectives) that you could use until such things become natively available. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
