Named after Wes Graham, the first director of the Computer Centre at Waterloo, the Graham system is a heterogeneous cluster, suitable for a variety of workloads. The parallel file system and external persistent storage are similar to the Cedar System’s, but the interconnect is different and there is a slightly different mix of compute nodes. The Graham system is entirely liquid cooled, using rear-door heat exchangers. Graham was designed to support multiple simultaneous parallel jobs of up to 1,024 cores in a fully non-blocking manner. This system has a total of 41,548 cores and 520 GPU devices, spread across 1,185 nodes of different types.
Best for: Active data storage and processing.
Suitable to store UBC data classified: Low Risk & Medium Risk
Default project space: 1 TB and 500K files per group
Default scratch space: 20 TB and 1M files per user. Scratch should be used only be used during compute time. This storage is not backed up and is subject to automated purge of older files.
Note: Storage is available only for the duration of the allocation.
