I would like to test the network latency/bandwidth of each node that I am running on in parallel. I think the simplest way to do this would be to have each node test itself.
My question is: How can I force all the OpenMPI TCP communication to go through the network adapter, and not use the optimized node-local communication? Any advice would be greatly appreciated. Best Regards, John
