Introduction

Since we got 12 dedicated GPU nodes (mpcg[001-009]) containing one NVIDIA Tesla P100 each and four additional nodes (mpc[001-004]) containing two GTX 1080 each, its possible to run your jobs with one or multiple associated GPUs. The usage might not be self-explanatory, we created this guide to help you get everything set up and working properly.

Examples

In order to use one or more GPUs for your Job you will have to request a Generic resource (GRES). You can do that by adding the following line to your jobscript:

#SBATCH --gres=gpu:1

This will request one GPU. A suitable node will be automatically chosen by SLURM.

Of couse its possible to request more than one GPU. With the following line of code you will request 3 GPUs:

#SBATCH --gres=gpu:3
