Despite this only 8 cores appear to be in use (12 out of 20 cores at virtually no use, 8 at 100%).

How do I force optimal core usage? (setting cores used to -1 does not work).

Re: F@H not using all available cores

Post by bikeaddict »

For big.LITTLE processors like the i9-12900HK with 6 performance cores, you should set it manually to 12 threads and then use a tool like Process Lasso to set affinity so FahCore_a7 and FahCore_a8 only run on the performance cores. The way GROMACS works is the threads only run as fast as the slowest one. If any thread runs on an efficiency core, they are all throttled down to that speed.
