Hi,
I just upgraded from the default ompi install on OS X 10.6 to v1.5.3
so that I can use the processor affinity options. However there seems

following CL statement:
/usr/local/openmpi-1.5.3/bin/mpiexec --host `hostname` --np 2

particular nodes. I am also able to run jobs through Xgrid (using
mpirun). My issu
