I have a dual 16 core machine (XEON 6226R), and am solving on 12 cores. When I go into Windows 10 task manager, and look at CPU Utilization, it looks like CFX is only using one of the processors. Is there any setting to change this, and wouldn't it be more efficient to use both? I don't know if this is a CFX thing or hardware thing, so forgive me for posting this in both forums.

NOTE: I am running CFX Distributed using IBMMPI to another identical machine. The other machine exhibits the same behavior as well.
I just repeated this using 18 cores per machine, and CPU usage shows 100% of the second Numa Node, and just a little bit of the first. So It prioritizes the 2nd numa node instead of distributing evenly, or cycling through all cores.

Testing IntelMPI local parallel on 12 cores: It splits it to about 8 cores on Numa Node 0 and 4 cores on Numa Node 1. Better than IBM MPI, but still not perfectly balanced.
