WebOct 8, 2024 · NVIDIA Multi-Process Service (MPS) is a facility that enables compute kernels submitted from multiple CPU processes to execute simultaneously on the same GPU. Such overlapping can potentially enable more thorough resource use and better overall throughput. WebThe GPU PME decomposition allows also distributing the PME computation across multiple GPUs including fast Fourier transforms thanks to the integration with distributed FFT libraries.

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.
