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
This cluster is based on the Slurm scheduler running on Ubuntu.
| Node name | OS | Cores | Memory | CPU | purchase date |

| cl3node01-20 | Ubuntu 20.04 | 32 cores (HT 64) | 256 Gb | Xeon Gold 6242 CPU @ 2.80GHz | 4 November 2020 |
| cl3node21-35 | Ubuntu 20.04 | 32 cores (HT 64) | 256 Gb | Xeon Gold 6326 CPU @ 2.90GHz | 3 November 2022 |
The nodes are connected by InfiniBand and the cluster is located in “het SeinHuis”.
You can connect to the headnode : ccphead.ewi.utwente.nl
We now use the new Slurm scheduler instead of searching for a free node and run our calculations
