I agree with you Ralph , and that 's what I expect from openmpi but
my second example shows that it's not working
cat hostfile.0
r011n002 slots=4
r011n003 slots=4
cat rankfile.0
rank 0=r011n002 slot=0
rank 1=r011n003 slot=1
mpirun --hostfile hostfile.0 -rf rankfile.0 -n 1 hostname : -n 1
hostname

The rankfile cuts across the entire job - it isn't applied on an
app_context basis. So the ranks in your rankfile must correspond to
the eventual rank of each process in the cmd line.
Unfortunately, that means you have to count ranks. In your case, you
only have four, so that makes life easier. Your rankfile would look
something like this:
rank 0=r001n001 slot=0
rank 1=r001n002 slot=1
rank 2=r001n001 slot=1
rank 3=r001n002 slot=2
