"WebFeb 9, 2024 · On a single node, there is no effect from PME GPU decomposition, as you still only have one total PME GPU. On two nodes, the use of two PME GPUs gives performance similar to that using a single PME GPU. The former is slightly slower for STMV and slightly faster for benchPEP-h.

WebOne issue with multi-GPU scaling is that PME causes a bottleneck when all of the non-PME work is equally divided between devices. Since alpha 10, we provide a way to control the amount of work assigned to the PME device by scaling back the number of PEs (CPU cores) for that device using the +pmePEs command line parameter.
