GPU Nodes on Lengau

The Lengau cluster at the CHPC includes 9 GPU compute nodes with a total of 30 Nvidia V100 GPU devices. There are 6 gpu200n nodes with 3 GPUs in each, and 3 gpu400n nodes with 4 GPUs in each.

GPU Node CPU Cores GPU Devices Interface
gpu2001 36 3× Nvidia V100 16GB PCIe
gpu2002 36 3× Nvidia V100 16GB PCIe
gpu2003 36 3× Nvidia V100 16GB PCIe
gpu2004 36 3× Nvidia V100 16GB PCIe
gpu2005 36 3× Nvidia V100 32GB PCIe
gpu2006 36 3× Nvidia V100 32GB PCIe
gpu4001 40 4× Nvidia V100 16GB NVlink
gpu4002 40 4× Nvidia V100 16GB NVlink
gpu4003 40 4× Nvidia V100 16GB NVlink
Jobs that require 1, 2 or 3 GPUs can be allocated to any node, and will share the node if the job does not use all the GPU devices on that node. Jobs that require 4 GPUs can only be allocated to gpu4* nodes and will not be shared, obviously.
The GPU nodes have 192GiB so a job script that requests an entire node could access approximately 188GiB (the operating system needs about 4GiB).

Policies

Access

Access to the GPU nodes is by PI application only through the CHPC Helpdesk.
