GP2 (SFU)

Introduction

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.

Attached Storage System

$HOME	Standard home directory Not allocated Small, standard quota Larger requests should be on $PROJECT
$SCRATCH Parallel High-performance filesystem	Approximately 4PB usable capacity for temporary (/scratch) storage. Aggregate performance of approximately 40GB/s. Available to all nodes. Not allocated Purged - inactive data will be purged
$PROJECT External persistent storage	Provided by the NDC. Available to compute nodes, but not designed for parallel i/o 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	128 GB of memory, 16 cores/socket, 2 sockets/node
"Large" compute nodes:	Over 100 nodes	256 GB of memory, 16 cores/socket, 2 sockets/node
"Bigmem512"	24 nodes	512 GB of memory, 16 cores/socket, 2 sockets/node
"Bigmem1500" nodes	24 nodes	1.5 TB of memory, 16 cores/socket, 2 sockets/node
"GPU base" nodes:	Over 100 nodes	128 GB of memory, 12 cores/socket, 2 sockets/node, 4 GPUs/node, 2 GPUs/socket.
"GPU large" nodes.	Approximately 30 nodes	256 GB of memory, 12 cores/socket, 2 sockets/node, 4 GPUs/node, All GPUs on the same socket
"Bigmem3000" nodes	4 nodes	3 TB of memory, 8 cores/socket, 4 sockets/node

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.
