<p class="MsoNormal">Today, doing some tests, I have not got a solution to write a submit script that requests 2 different GPUs on 2 different nodes. With this simple script:<o:p></o:p></p>

<p class="MsoNormal">I get a parallel MPI job in two nodes, two process in each node and one GeForceRTX3080 in each node. However, if I want to request 2 different GPUs, I can’t write “#SBATCH --gres=gpu:GeForceRTX3080:1, --gres=gpu:GeForceRTX2070:1” because
line “#SBATCH --gres=” is for each node and, then, a line containing two “gres” would request a node with 2 different GPUs. So… is it possible to request 2 different GPUs in 2 different nodes?<o:p></o:p></p>
