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
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
If you do "man orte_hosts", you'll see a full explanation of how the various
machinefile options work.
The default mapper doesn't do any type of sorting - it is a round-robin
mapper that just works its way through the provided nodes. We don't reorder
them in any way.
However, it does depend on the
