XDG Nodes¶
We have 2 Dell PowerEdge XE8640 nodes with Nvidia Hopper H100 80GB cards for GPU jobs.
Accessing the XDG nodes
The XDG nodes are restricted to users within the Science and Engineering (S&E) faculty only.
GPU high memory
The XDG nodes have more RAM available than standard GPU nodes, supporting
up to 240G RAM per GPU (16 tasks per GPU). Authorised users may use the
--mem-per-cpu=15G submission parameter to request larger amounts of RAM
on these nodes.
