If the application "ensures" that there are no messages in-flight, then I agree with you. I was thinking of applications that use asyncronous MPI communication in a multi-threaded env, potentially leading to unmatched messages.....
Right, so what would you like MPI to do in that case? Are you focused on the global checkpointing case or the case where each process may checkpoint independently? Greg Bronevetsky Post-Doctoral Researcher 1028 Building 451 Lawrence Livermore National Lab (925) 424-5756 [email protected]
