2012-02-29 Thread Eric Chamberland
Hi, I would like to know which of "waitone" vs "waitany" is optimal and of course, will never produce deadlocks. Let's say we have "lNp" processes and they want to send an array of int of length "lNbInt" to process "0" in a non-blocking MPI_Isend (instead of MPI_Gather). Let's say the
