Compute Resources

CPUs

  • Resources are orgnized into partitions on the cluster based on functionality and priority.
  • After logging in on the HPC cluster, you can use command sinfo to check the partition you have access to (all partitions listed in the sinfo output).

GPUs

  • NVIDIA GPUs are available in gpu and preempt partitions

  • Request GPU resources with --gres. See details below.

  • Please DO NOT manually set CUDA_VISIBLE_DEVICES.
  • Users can ONLY see GPU devices that are assigned to them with $ nvidia-smi.
  • gpu partition-p gpu:
  • NVIDIA P100s
    • In "gpu" partition
    • Request with: --gres=gpu:p100:1(one P100 GPU, can request up to 6 on one node)
  • NVIDIA Tesla K20xm
    • In "gpu" partition
    • Request with: --gres=gpu:k20xm:1(one Tesla K20xm GPU, can request up to 1 on one node)
