IIHE local cluster

Overview

The cluster is composed by 4 machine types :

  • User Interfaces (UI)

This is the cluster front-end, to use the cluster, you need to log into those machines

  • Computing Element (CE)

This server is the core of the batch system : it run submitted jobs on worker nodes

  • Worker Nodes (WN)

This is the power of the cluster : they run jobs and send the status back to the CE

  • Storage Elements

This is the memory of the cluster : they contains data, software, ...


To connect to the cluster, you must use your IIHE credentials (same as for wifi)

ssh username@icecube.iihe.ac.be

After a successful login, you'll see this message :
