Gromacs performance on different GPU types - FAU

WebYou can run Gromacs on gpu machines. However the performance are not guarantee to be better on GPUs machines due to the overhead generated, so more CPUs may sometime performs faster than running on GPU. OpenMP has been disabled during compilation for all the Gromacs in the GPU machines. WebFor that reason, GROMACS 2024 introduced a GPU-resident parallelization mode which, by moving integration and constraints to the GPU, can avoid the frequent CPU–GPU data movement and synchronization and with that prioritizes keeping the GPU busy. WebRequesting (GPU) resources. There are 2 main ways to ask for GPUs as part of a job: Either as a node property (similar to the number of cores per node specified via ppn) using -l nodes=X:ppn=Y:gpus=Z (where the ppn=Y is optional), or as a separate resource request (similar to the amount of memory) via -l gpus=Z. good luck on your new adventure image
