System Architecture
All Ferranti nodes run Rocky 8.8 and resource allocation is managed using Slurm (resource manager).
Global storage is provided by a Weka file system ($HOME, $WORK, datasets).
Inter-node communication uses a InfiniBand 400G non-blocking network.
Ferranti also has Ceph archival storage available for users.
The system is composed of 2 login nodes, 2 CPU-only nodes, and 15 H100 nodes, housed in 10 air-cooled racks.
