GPU Nodes
The Lengau cluster at the CHPC includes 9 GPU compute nodes with a total of 24 Nvidia V100 GPU devices.
Access to these GPU node is by PI application only though the CHPC Helpdesk.
Research programme allocations will be depleted by a factor of the wallclock time and the number of GPUs (1, 2, or 4) requested by the job.
gpu_allocation_used = 40 * runtime * ngpus
GPU Job Scripts
GPU Queues
There are three queues available in PBSPro which access the GPU nodes:
| Queue name | Max. CPUs | Max. GPUs | PBSPro options | Comments |
|---|---|---|---|---|
| gpu_1 | 10 | 1 | -q gpu_1-l ncpus=10:ngpus=1 | Access one GPU device only. |
| gpu_2 | 20 | 2 | -q gpu_2-l ncpus=20:ngpus=2 | Access two GPU devices. |
| gpu_4 | 40 | 4 | -q gpu_4-l ncpus=40:ngpus=4 | Access four GPU devices on NVLink nodes. |
