A multi-threaded software(PFC3D-to do simulation) not using all the available cores

Question

Hi all,

I'm using a multi-threaded software(PFC3D developped by Itasca consulting) to do some simulations.After moving to a powerful computer Intel Xeon Gold 5120T CPU 2.2GHZ 2.19 GHZ  (2 Processors)(28 physical cores, 56 logical cores)(Windows10) to have rapid calculations, the software seems to only use a limited number of cores.Normally the number of cores detected in the software is 56 and it takes automaticly the maximum number of cores.

I'm pretty sure that the problem is in the system not in my software because I'm running the same code in a intel core i9-9880H Processor (16 logical cores) and it'is using all the cores with even more efficiency than the xeon gold.

I appreciate very much your precious help.

Thank you

Youssef
