We use two process. (xeon e5-2699-v3)
The number of the core is 72.Why do not the choice out of 36 at the start of the solver?
Because the physical number of cores is actually 36 not 72, which is the number of virtual cores when hyperthreading is used.
Flow Sim (2014) defaults to 40 CPUs for me, even though only 20 of them are real (dual Xeon E5-2670 v2).
maybe a 2015 vs 2014?
there are 3 different threads going on here
