GP2 (SFU)

The GP2 system evaluation is not yet completed (as of early November 2016). Anticipated specifications, based on SFU's RFP and bids received, include the following. This information is not guaranteed and might not be complete. It is provided for planning purposes.

Parallel filesystem:

Approximately 4PB usable capacity for temporary (/scratch) storage.
Aggregate performance of approximately 40GB/s. Available to all nodes.

External persistent storage:

10PB or more of storage for persistent (/project and other) storage.
Available to compute nodes, but not designed for parallel workloads.

High performance interconnect:

Low-latency high-performance fabric connecting all nodes and temporary storage.
The design of GP2 is to support multiple simultaneous parallel jobs of at least 1024 cores in a fully non-blocking manner. Jobs larger than 1024 cores would be less well-suited for the topology.

Node types and characteristics:

"Base" compute nodes: Over 500 nodes 128GB of memory each
"Large" compute nodes: Over 100 nodes 256GB of memory each
"Bigmem512" 24 nodes 512 GB of memory each
"Bigmem1500" nodes 24 nodes 1.5TB of memory each

All of the above nodes will have 16 cores/socket (32 cores/node), with an anticipated frequency of 2.1Ghz.

"GPU base" nodes: Over 100 nodes with 4 GPUs each. 12 cores/socket (24 cores/node) with an anticipated frequency of 2.2Ghz. GPUs on a dual PCI root.
"GPU large" nodes. Approximately 30 nodes same configuration as "GPU base," but a single PCI root.
"Bigmem3000" nodes 4 nodes each with 3TB of memory. These are 4-socket nodes with 8 cores/socket.

All of the above nodes will have local (on-node) storage.

Compute Canada is not currently able to disclose the specific GPU model or specifications. The RFP used NVIDIA K80 as a baseline specification.

The total GP2 system is anticipated to have over 25,000 cores, 900 nodes, and 500 GPUs.

The delivery and installation schedule is not yet known, but the procurement team has confidence that the system will be in production for the start of the allocations year on April 1, 2017.
