Hi folks In case you didn't follow this on the user list, we had a question come up about proper OMPI behavior. Basically, the user has an application where one process decides it should cleanly terminate prior to calling MPI_Init, but all the others go ahead and enter MPI_Init. The application hangs since we don't detect the one proc's exit as an abnormal termination (no segfault, and it didn't call MPI_Init so it isn't required to call MPI_Finalize prior to termination).
I can probably come up with a way to detect this scenario and abort it. But before I spend the effort chasing this down, my question to you MPI folks is: What -should- OMPI do in this situation? We have never previously detected such behavior - was this an oversight, or is this simply a "bad" application? Thanks Ralph
