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.

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
