Single-GPU jobs were run on a single GPU with ntasks=2, n-tasks-per-core=1, and ntomp=2. These results may be different for larger molecular systems, so please run your own benchmarks to verify that your jobs benefit from the GPUs (and send us any interesting results!) WebBy using the `--gpus-per-task` flag we can request one GPU per MPI rank. ... We then used `--cpus-per-task`, this was done since GROMACS requires at least two threads per MPI rank so that each MPI rank has one computation thread and one communication thread. ... per node which corresponds to the number of GPUs per node and each of these MPI ... new hope gas company goldsboro nc

"WebThe non-bonded free-energy kernel is a factor 2.5 faster with non-zero A and B states and a factor 1.5 with one zero state. This especially improves the run performance when non-perturbed non-bondeds are offloaded to a GPU. In that case the PME-mesh calculation now always takes the most CPU time.

Best graphics card for running gromacs - NVIDIA Developer Forums

WebAug 31, 2024 · The limitation is that Gromacs performs some computation on the CPU and some on the GPU, so CPU may be a limiting factor. I would like to benchmark this before getting a second GPU. -Gromacs generally has modest memory use. For my largest systems (~1,000,000 atoms), the usage is <1GB/core. WebGROMACS will not run GPU runs with only 1 OpenMP thread, unless forced by setting the -ntomp option. According to GROMACS developers, the optimum number of --cpus-per-task is between 2 and 6. Avoid using a larger fraction of CPUs and memory than the fraction of GPUs you have requested in a node.
