CCP Cluster
One of the clusters at the University is the CCP 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
- regular compute nodes (where computations are running)
This cluster is based on the Slurm scheduler running on Ubuntu.

Login Nodes
You can connect to the headnode : ccphead.ewi.utwente.nl
Slurm
We now use the new Slurm scheduler instead of searching for a free node and run our calculations
