\item \error{MPI\_ERR\_PROC\_FAILED\_PENDING} indicates, for a non-blocking communication, that the communication is a receive operation from \const{MPI\_ANY\_SOURCE} and no send operation has matched, yet a potential sender process has failed. Neither the operation nor the request identifying the operation are completed.

The text describing MPI_ERR_PROC_FAILED_PENDING isn’t quite accurate. It says that no send has been posted, but it should actually say that no send has been matched (who knows what’s been posted but not received yet). Wesley

New draft that separates ERR_PENDING from ERR_PROC_FAILED_PENDING
by Aurélien Bouteiller 24 Jan '14

24 Jan '14

Please review the draft that modifies the errors ERR_PENDING into ERR_PROC_FAILED_PENDING The name of the error code is rather long. Shorter error name propositions are welcome. MPI_ERR_WOULDBLOCK ??? For references, and this was the only though worthy issue for this change, the document intentionally doesn’t specify what the implementation behavior must be for ERR_PENDING when ERR_PROC_FAILED_PENDING could be raised (or the contrary). MPI_Irecv(ANY_SOURCE, comm1, &r1) MPI_Irecv(ANY_SOURCE, comm1, &r2) MPI_WaitAll(r1,r2) can legitimately result in err_status(r1): PROC_FAILED_PENDING err_status(r2): PROC_FAILED_PENDING err_status(r1): PENDING err_status(r2): PROC_FAILED_PENDING err_status(r1): PROC_FAILED_PENDING err_status(r1): PENDING
