==Compute==
==Compute clusters== <!--T:1-->


===Overview===
<!--T:3-->
A ''general-purpose'' cluster is designed to support a wide variety of types of jobs, and is composed of a mixture of different nodes.  We broadly classify the nodes as:
* ''base'' nodes, containing typically about 4GB of memory per core;
* ''large-memory'' nodes, containing typically more than 8GB memory per core;
* ''GPU'' nodes, which contain [https://en.wikipedia.org/wiki/Graphics_processing_unit graphic processing units].


GP2 and GP3 are almost identical systems with some minor differences in the actual mix of large memory, small memory and GPU nodes.
<!--T:17-->
The ''large parallel'' cluster [[Niagara]] is designed to support multi-node parallel jobs requiring more than 1000 CPU cores, although jobs as small as a single node are also supported there.  Niagara is composed of nodes of a uniform design, with an interconnect optimized for large jobs.

====Node types and characteristics:====
 
"Base" compute nodes: Over 500 nodes with 128GB of memory.
 
"Large" compute nodes: Over 100 nodes with 256GB of memory.
 
"Bigmem512" and "Bigmem1500" nodes, each with 512GB and 1.5TB of memory respectively.  24 of each type.
 
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 x4 GPUs.  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 with the same configuration as "GPU base," but a single PCI root.
 
"Bigmem3000" nodes, each with 3TB of memory.  These are 4-socket nodes with 8 cores/socket.  4 nodes.
 
All of the above nodes will have local (on-node) storage.

Gateway and data transfer nodes
 
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.

Compute clusters

A general-purpose cluster is designed to support a wide variety of types of jobs, and is composed of a mixture of different nodes. We broadly classify the nodes as:

  • base nodes, containing typically about 4GB of memory per core;
  • large-memory nodes, containing typically more than 8GB memory per core;
  • GPU nodes, which contain graphic processing units.

The large parallel cluster Niagara is designed to support multi-node parallel jobs requiring more than 1000 CPU cores, although jobs as small as a single node are also supported there. Niagara is composed of nodes of a uniform design, with an interconnect optimized for large jobs.

All clusters have large, high-performance storage attached. For details about storage, memory, CPU model and count, GPU model and count, and the number of nodes at each site, please click on the cluster name in the table below.
