Hi Ralph,
Thanks for the reply. The default mapper does round-robin assignment
as long as I do not specify the machinefile in the following format:
n1
n2
n2
n1where, n1 and n2 are two nodes in the cluster and I use two
slots within each node.
I have pasted the output and the display map fo
Thanks, that at least explains what is going on. Because I have an
unbalanced work load (at least for now) I assume that I'll need to poll. If
I replace the compositor loop with the following, it appears that I prevent
the serialization/starvation and service the servers equally. I can think of

Ah, yes - that is definitely true. What you need to use is the "seq" (for
"sequential") mapper. Do the following on your cmd line:
--hostfile hostfile -mca rmaps seq
This will cause OMPI to map the process ranks according to the order in the
hostfile. You need to specify one line for each node/ran
Thanks Ralph. It worked.
Regards,
Rajesh

cluster using OPEN MPI. But I am now facing another problem.
When i tried restarting the checkpoint, nothing happens. I copied the
checkpoint file to the $HOME directory and tried restarting it there and go
