[mvapich-discuss] can't run mvapich MPI job in background

[Benjamin Rutt]

I'm using mvapich 0.9.7.tar.gz using make.mvapich.gen2 build script.
I'm trying to run a job in the background under bash shell, but it
seems to not work correctly.  Does anyone know what's preventing me
from doing this?

foreground version:

    [rutt at node23 test]$ mpirun_rsh -rsh -np 2 node23 node24 ./mpi-hello-world 
    Processor 1 of 2: Hello World on node23
    Processor 2 of 2: Hello World on node24

background attempt:

    [rutt at node23 test]$ mpirun_rsh -rsh -np 2 node23 node24 ./mpi-hello-world &
    [1] 2257
    [rutt at node23 test]$ 
    [1]+  Stopped                 mpirun_rsh -rsh -np 2 node23 node24 ./mpi-hello-world

[...time passes, I try to foreground the job...]

    [rutt at node23 test]$ fg
    mpirun_rsh -rsh -np 2 node23 node24 ./mpi-hello-world
    done.

Thanks,
