Christopher, how would I check that? I got Torque/Maui/OpenMPI up, 
working with root (not with normal user yet :( !!!), tried mpirun and it 
worked fine:

# /usr/lib64/openmpi/bin/mpirun -pernode --hostfile 
/home/mpiwulf/.openmpihostfile /home/mpiwulf/test/mpihello
Hello world!  I am process number: 3 on host node0118
Hello world!  I am process number: 1 on host node0104
Hello world!  I am process number: 0 on host node0103
Hello world!  I am process number: 2 on host node0117

Thanks,

D.
