# HPC Cluster

The **HPC Cluster** is the CSL's main **H**igh **P**erformance **C**omputing Cluster.

**It should only be accessed through** [Slurm](/services/cluster/slurm.md)! See the page on [Cluster](/services/cluster.md) for more details.

## Technical Specifications

There are 12 nodes in the cluster, each part of a 4-node SuperMicro 4U SuperBlade, each with the same specifications:

## Trivia

Each of the nodes in the HPC cluster is named after a [robot from Futurama](https://en.wikipedia.org/wiki/List_of_Futurama_characters), making them hard to remember (although not nearly as hard as the [Borg Cluster](/machines/borg-cluster.md)!).
