Yes, this works! Very good trick... The system routine would be more
flexible, b
of this.

Hi,
I am a long time happy user of mpi_comm_spawn() routine. But so far I
used it only with the MPI_COMM_WORLD communicator. Now I want to
execute more mpi_comm_spawn() routines, by creating and using group
communicators. However this seems to have some problems. I can get it
to run about 50% time
