Compute clusters

All general-purpose systems are similar with some differences in interconnect and the number of small memory, large memory and GPU nodes. Niagara is a different system and is designed for large parallel jobs.

All systems have large, high-performance attached storage; see the relevant cluster page for more details.

Types of compute clusters

Type	Type of nodes	Type of jobs
General-purpose	Small memory nodes Regular nodes (4GB/core) Large memory nodes GPU nodes	Serial and small parallel jobs Small or large memory jobs GPU jobs
Large parallel	Uniform nodes (4GB/core) Optimized interconnect	Parallel jobs requiring +1000 cores

Cloud - Infrastructure as a Service

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