Hi, I am doing some benchmarks and would like to test the following two scenarios. Each machine has 4 sockets each with 6 cores (lstopo image attached).
Scenario 1 --- Run 12 procs per node each bound to 2 cores. I can do this by --map-by socket:PE=2 Scenario 2 Run 12 procs per node each bound to just 1 core. This is what I don't know how to do, because if I do --map-by socket:PE=1 then mpirun will put more than 12 procs per node as it can do so. I'd appreciate any help on this.
