===== TFE2 Cluster =====
One of the clusters at the University is the TFE2 Cluster

This HPC cluster is a collection of many separate servers (computers), called nodes, which are connected via a fast interconnect.

There may be different types of nodes for different types of tasks. The HPC cluster listed on this wiki has

a headnode or login node, where users log in
  * multiple data nodes
  * regular compute nodes (where majority of computations is run)
  * All cluster nodes have the same components as a laptop or desktop: CPU cores, memory and disk space. The difference between personal computer and a cluster node is in quantity, quality and power of the components.

This cluster is based on the **[[https://www.schedmd.com/index.php|Slurm scheduler]]** running on Ubuntu
