Doing MPI_Isend()
followed by a MPI_Cancel() fails on my PSM based system with 1.8.4 like this: n040108:0.1.Cannot cancel send requests (req=0x2b6279787f80) n040108:0.0.Cannot cancel send requests (req=0x2b3a3dc92f80) ------------------------------------------------------- Primary job terminated normally, but 1 process returned a non-zero exit code.. Per user-direction, the job has been aborted. ------------------------------------------------------- -------------------------------------------------------------------------- mpirun detected that one or more processes exited with non-zero status, thus causing the job to be terminated. The first process to do so was: Process name: [[58364,1],1] Exit code: 255 -------------------------------------------------------------------------- Is this something PSM actually cannot do or an Open MPI error?
