ILCC Cluster

Printer-friendly versionPrinter-friendly version

The ILCC cluster is for members of ILCC and for CDT in NLP students.

Types of hardware

This cluster has several types of computer node. Access is transitioning from ssh access to slurm controlled access.

The head node
The head node is called ilcc-cluster. To use the slurm controlled nodes, first ssh ilcc-cluster then use Slurm.

Here's how to use a cluster without breaking it:

Schedule your jobs with Slurm

Use of this cluster's GPU nodes is controlled by Slurm.

Software

The cluster runs the standard SL7 version of DICE. If you would like software to be added, please ask Computing Support.

Files and backups

  • Jobs on the compute nodes cannot access your files in AFS. Instead there are home directories on a local distributed filesystem. You can copy files from AFS by logging in to a head node then using the cp command. AFS home directories can be found under /afs/inf.ed.ac.uk/user/. ot you can download files directly to the local disk space on the node.
  • There is no disk quota but space is limited so please delete files you have finished with.
  • Your files are NOT backed up. DO NOT USE THIS FILESYSTEM AS THE ONLY STORAGE FOR IMPORTANT DATA. Disk space may be reclaimed once your access has finished. It is your responsibility to make copies of anything you wish to keep. There is some redundancy for disaster recovery.
  • please tidy up files on the local disk when you're finished using them. Note that files in /disk/scratch will be automatically deleted if they have not been accessed for over 90 days.

Pre-existing files on the nodes

If you have data in scratch space on the nodes you can access it by running an srun job on the head node and specifying -p --nodename= like this

srun -p ILCC_GPU --nodelist=ostrom --pty bash
[ostrom]iainr: cd /disk/scratch
[ostrom]iainr: ls
