SubscriberDear team,
I'm using Discovery R2024R1 SP2. I'm doing some topology optimization runs and I see that apart form the GPU, Nvidia RTX A4500 16 GB laptop, the CPU, Intel Core i7-12850HX, gets loaded to around 100%. As the CPU is of an Alder Lake hybrid architecture with 8x P-("performance") and 8x E-("efficiency") cores, I would like to reduce the number of cores used by Discovery just to the P-cores. I know the internal Intel Thread Director is doing its best, but I want to do some testing.Â
Is there an option of setting this? Under the Settings-> Physics -> Solver Settngs there is a pull down menu for number of cores, but this is most probaly influencing only the Refine Mechanical APDL solver.
Any suggestions?

Best regards

Forum ModeratorHello Deyan,
Let me check if this can be done. As far as I understand, it is likely that the GPU cores can not be reduced, if you are using the Explore stage. Having said that, you can change the global settings for fidelity to restrict the GPU usage.
Please try that out.Â

SubscriberHello Charudatta,Â
yes, I'm a trying a topology optimization within the Explre mode. But the CPU is loaded at 100% either. And I want to reduce the number of the used cores of the CPU only to the P-cores, the performace onece.
