Is it possible to let only one MPI process write to the Standard error RRS feed

  • Question

  • I am running a MPI program on Windows HPC Pack cluster. It failed on 12 nodes and spit out some unreadable messages to Standard error file specify. Is it possible to only let one MPI process to write to Standard error so that I can see what the error message is? Thanks for your time.

  • Individual mpi processes are not writing to standard output / error. Output and error streams are being passed up to mpiexec process that does the actual writing.
