Translations:Using GPUs with Slurm/10/en

There is a special group of GPU nodes on Cedar which have four Tesla P100 16GB cards each (Other P100 GPUs on the cluster have 12GB and the V100 GPUs have 32G). The GPUs in a P100L node all use the same PCI switch, so the inter-GPU communication latency is lower, but bandwidth between CPU and GPU is lower than on the regular GPU nodes. The nodes also have 256GB RAM. You may only request these nodes as whole nodes, therefore you must specify --gres=gpu:p100l:4. P100L GPU jobs up to 28 days can be run on Cedar.
