What is Zest?

Zest is a High Performance Computing (HPC) cluster for campus researchers which supports tying together multiple compute nodes for research work that cannot be split into smaller components or fit within a single machine. 

To facilitate this, Zest compute elements are interconnected with low-latency networking that pass information between nodes many times faster than traditional network technologies. Zest utilizes the SLURM scheduler, which allows researchers to scale jobs within the cluster and groups the nodes together as needed by the current jobs. 

At its inception in 2020, Zest is made up of over 1000 cores and 6TB of memory across 31 interconnected nodes.
