[Pw_forum] mpirun problem in queuing system!

  I think the problem is PBS can't redirect the standard output of all of
  your processes (because PBS doesn't have the control of processes
  started by mpirun). The problem  can be resolved using mpiexec
  http://www.osc.edu/~pw/mpiexec/  ...

  A simpler solution could be to  try  to indicate your
  standard output file to PBS

  # -o output


  eliminate the explicit redirection "> mg.out"
