Vulcan is a cluster dedicated to the needs of the Canadian scientific Artificial Intelligence community. Vulcan is located at the University of Alberta and is managed by the University of Alberta and Amii. It is named after the town Vulcan, AB, located in southern Alberta.

This cluster is part of the Pan-Canadian AI Compute Environment (PAICE).

Vulcan hardware specifications

Performance Tier	Nodes	Model	CPU	Cores	System Memory	GPUs per node	Total GPUs
Standard Compute	202	Dell R760xa	2 x Intel Xeon Gold 6448Y	64	512 GB	4 x NVIDIA L40s 48GB	808

Storage System

Vulcan's storage system uses a combination of NVMe flash and HDD storage running on the Dell PowerScale platform with a total usable capacity of approximately 5PB.

Home space xxxTB total volume	Location of /home directories. Each /home directory has a small fixed quota. Not allocated via RAS or RAC. Larger requests go to the /project space. Has daily backup
Scratch space xPB total volume Parallel high-performance filesystem	For active or temporary (scratch) storage. Not allocated. Large fixed quota per user. Inactive data will be purged.
Project space xPB total volume External persistent storage	Large adjustable quota per project. Has daily backup.

Network Interconnects

Standard Compute nodes are interconnected with 100Gbps Ethernet with RoCE enabled.

Scheduling

The Vulcan cluster uses the Slurm scheduler to run user workloads. The basic scheduling commands are similar to the other national systems.

Software

• Module-based software stack.
• Both the standard Alliance software stack as well as cluster-specific software.
