Macros, yes, refer to the example script Matt mentioned for Summit. Feel free to turn on/off options in the file. In my experience, gcc is easier to use. Also, I found https://docs.alcf.anl.gov/polaris/running-jobs/#binding-mpi-ranks-to-gpus, which might be similar to your machine (4 GPUs per node). The key point is: The Cray MPI on Polaris does not currently support binding MPI ranks to GPUs. For applications that need this support, this instead can be handled by use of a small helper script that will appropriately set CUDA_VISIBLE_DEVICES for each MPI rank. So you can try the helper script set_affinity_gpu_polaris.sh to manually set CUDA_VISIBLE_DEVICES. In other words, make the script on your PATH and then run your job with srun -N 2 -n 16 set_affinity_gpu_polaris.sh /home/mnv/Firemodels_fork/fds/Build/ompi_gnu_linux/fds_ompi_gnu_linux test.fds -pc_type gamg -mat_type aijcusparse -vec_type cuda
Then, check again with nvidia-smi to see if GPU memory is evenly allocated. --Junchao Zhang On Tue, Aug 22, 2023 at 3:03 PM Matthew Knepley <knep...@gmail.com> wrote: > On Tue, Aug 22, 2023 at 2:54 PM Vanella, Marcos (Fed) via petsc-users < > petsc-users@mcs.anl.gov> wrote: > >> Hi Junchao, both the slurm scontrol show job_id -dd and looking at >> CUDA_VISIBLE_DEVICES does not provide information about which MPI >> process is associated to which GPU in the node in our system.
