Thank you, Cesar. We think we have it working now. The documentation was a little confusing.
We can either add cpu=n in each row of the hostsfile lamboot uses, or we can use mpirun -np <NUM_OF_INSTANCES> prog where we make <NUM _OF_INSTANCES> the number of cpus on all of the nodes. Thank you for replying.

Have you executed lamboot first? 2011/3/1 Sue McGlashan <sue.mcglas...@utoronto.ca<mailto:sue.mcglas...@utoronto.ca>> Hi I apologise if this is the wrong list, but I think it is likely an oscar user will know the answer. Running mpirun C process_name should cause the process to run on every CPU. I am running RHEL 5.5. The nodes have dual core quad processors, so I should see, I believe, 8 cpus per node when I run the above command. However, I see only one per node. This is likely a set up problem. I would appreciate a pointer to what I am doing wrong.
