and it should do the Right ordering for you. If you don't want this,
you can change the default mapping to be "by node", so it will allocate
one process per node until all slots are taken. For example:
mpirun -np 2 --hostfile hostfile ./x
will put MCW rank 0 on host1 and MCW rank 1 on host2.
That should be:
mpirun -np 2 --hostfile hostfile --bynode ./x
Sorry for the confusion...
