How does Fluent manage e/p-cores?

Hi guys, I'm running CFD simulations with Fluent 2022R2 and my workstation has an Intel i9 12950HX CPU. As you probably already know, Intel Alder Lake processors adopt efficiency and performance cores (12950HX has 8 e-cores and 8 p-cores). I deactivated Hyper-Threading and I tried to run a simulation using only 8 cores; the CPU has a Max Turbo Boost Frequency @ 5 GHz for the p-cores, but during the simulation it seems that the processor settles between 3.2 - 3.4 GHz (which is pretty low). So, how does the solver choose the cores for the calculation?
Thanks |
