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.

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 link for each cluster in the table below.

Cloud - Infrastructure as a Service

Our cloud systems are offering an Infrastructure as a Service (IaaS) based on OpenStack.
