| + | |||
| + | To run this example, create the Python script and Slurm batch script provided below. | ||
| + | |||
| + | The Python script uses the mpi4py library to measure MPI communication performance with the classic ping-pong benchmark. The Slurm script loads the required modules and submits the job across 2 nodes. | ||
| + | |||
| + | Optional interactive testing: | ||
| + | <code bash> | ||
| + | srun --partition=short --ntasks=2 --gres=gpu: | ||
| + | </ | ||
| + | |||
| + | Use this command to request an interactive session on a single node for experimentation. | ||
