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 Slurm scheduler running on Ubuntu
