===== AM Cluster =====

One of the clusters at the University is the AM 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 **[[https://www.schedmd.com/index.php|Slurm scheduler]]** running on Ubuntu.

=== Hardware Specifications AM Cluster ===

^Node name^OS^Cores^Memory^CPU^purchase date^
| amhead | Ubuntu 20.04 | 16 cores (HT 32) | 96 Gb | Xeon CPU Silver 4216 @ 2.10GHz | 16 March 2020 |
| amnode01-08 | Ubuntu 20.04 | 32 cores (HT 64) | 192 Gb | Xeon CPU Silver 4216 @ 2.10GHz | 16 March 2020 |

The nodes are connected by InfiniBand and the cluster is located in "het SeinHuis".

===  Login Nodes === 
You can connect to the headnode : amhead.ewi.utwente.nl\\
\\
==== Slurm ====
We now use the new Slurm scheduler instead of searching for a free node and run our calculations\\
for info see [[slurm:start|Slurm]] and [[https://slurm.schedmd.com/quickstart.html|the Slurm quickstart]]
