[[Cedar]] (GP2) and [[Graham]] (GP3) are general purpose clusters composed of a variety of nodes including large memory nodes and nodes with accelerators. They went into service in the summer of 2017. You can log in to either one using [[SSH]] and the same password you use at ccdb.computecanada.ca. A home directory will be automatically created for you the first time you log in. | [[Cedar]] (GP2) and [[Graham]] (GP3) are general purpose clusters composed of a variety of nodes including large memory nodes and nodes with accelerators.

Most 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 legacy clusters are classified as either capacity clusters or capability clusters.
