[mvapich-discuss] mpirun_rsh is not launching large jobs in version 1.4

[Craig Tierney]

When I try and launch a large application using mpirun_rsh
under mvapich2-1.4, I get the following error:

# $MPICH/bin/mpirun_rsh -hostfile $MACHINE_FILE -np 2048 ./wrf.exe
Word too long.
#

If I reduce the cores to use slightly, I can get the application to launch.
