So this means that the internal operation of OpenSM with the simulator is identical to its operation with real hardware? I have done some performance test with IBMgtSim and OpenSM running on separate machines and to me it looks like there is very little concurrency between the two processes. I.e. it looks like they spend a lot of time waiting for each other. Below are some results from a few simulation runs, the observed CPU utilization seems quite low. I would have expected much higher CPU load for IBMgtSim... Any thoughts on how this matches your experience?
