Double check that the (sender_rank, tag, communicator) tuple that you issued in the MPI_Irecv matches the (rank, tag, communicator) tuple from the sender (tag and communicator are arguments on the sending side, and rank is the rank of the sender in that communicator). When receives block like this without completing like this, it usually means a mismatch between the tuples. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
