Compute Canada is currently installing several million dollars’ worth of new computers while simultaneously retiring many old computers. During the transition period (2016-2018), a changing mix of old and new computers will be available to you. You can read about the progress of the migration from old to new systems [https://www.computecanada.ca/research-portal/accessing-resources/migration/ here]. | Compute Canada is currently installing several million dollars’ worth of new computers while simultaneously retiring many old computers.

Compute Canada has begun to renew its infrastructure starting in 2016. The first phase of the new deployment is composed of four new clusters, currently called GP1, GP2, GP3 and LP. While the [https://www.computecanada.ca/research-portal/accessing-resources/migration/ details] are still subject to change, GP1 will be an extension of the existing West Cloud, GP2 and GP3 will be general purpose clusters composed of a variety of nodes including large memory nodes and nodes with accelerators, and LP will be a large parallel cluster with nodes interconnected by a fast network. | Compute Canada has begun to renew its infrastructure starting in 2016.

Most [https://www.computecanada.ca/research-portal/national-services/compute/ legacy clusters] are classified as either capacity clusters or capability clusters. ''Capacity clusters'' contain nodes connected to each other by a relatively slow Ethernet network, while the ''capability clusters'' have a fast network, usually InfiniBand. Large parallel jobs will run better on capability clusters than capacity clusters, while smaller jobs will run almost anywhere. | Most [https://www.computecanada.ca/research-portal/national-services/compute/ legacy clusters] are classified as either capacity clusters or capability clusters.

There are some specialty clusters among the legacy resources. Applications which require more than 512 GB or memory per node require ''large shared memory systems''.

Compute Canada also has clusters equipped with accelerators such as [https://en.wikipedia.org/wiki/General-purpose_computing_on_graphics_processing_units GPUs] and Intel [https://en.wikipedia.org/wiki/Xeon_Phi Xeon Phis].
