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 ... WebThere is typically no advantage to running on more than a single GPU device. 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!)
CUDA driver and runtime mismatch - NVIDIA Developer Forums
WebOct 8, 2024 · Often, a separate CPU task, such as an MPI task, is used to control each GPU and perform any compute workload that is not offloaded to the GPU. In some … WebThis means constraining all bonds is not supported, except for small molecules, and box sizes close to half the pair-list cutoff are not supported. The number of coupled constraints is higher than supported in the GPU LINCS code. Will use CPU version of update. harry and the hendersons movie images

WebOct 12, 2024 · The API reported: CUDA driver version is insufficient for CUDA runtime version GROMACS cannot run tasks on a GPU. I am working on a shared computer … 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.
