Additional Resource Requests§

We recognise that researchers may sometimes require a higher throughput of work than it is possible to achieve with free ‘fair share’ usage of Legion, Myriad, and Grace. There a couple of ways of obtaining additional Legion resource beyond this fair share:

Make a special request to the CRAG for free access to additional resources§

Users who wish to request additional resources or reserve resources beyond those provided can complete the additional resource request form in collaboration with your supervisor or the project's principal investigator. This includes requests for increased storage quotas.

The completed form should be sent to the Research Computing Platforms team at, for technical review. If successful, your case will be presented to the CRAG for consideration at the next meeting of the Group. The CRAG meets monthly, usually on the third Friday of the month, and users will be informed of the Group’s decision as soon as possible after their next meeting.

Note that an application to the CRAG for additional resources is only likely to be approved if the impact on other users is not deemed to be significant, or of long duration.

Request hosting of shared datasets§

We have provision for hosting shared datasets for users on Myriad. These can be datasets that are freely accessible by all users, or ones limited to groups.

Hosted datasets:

  • Will not be backed up.
  • Must have a named primary contact.
  • Must be reapplied for every 12 months to make sure they are still current and required.
  • Will have an associated quota.
  • Will be removed when renewal lapses (notice will be given).

They are likely to be managed by a role account - access to the role account will be by ssh key.

To apply for a hosted dataset, please send this form to

Purchase dedicated compute nodes within Legion or Myriad§

There has previously been a programme allowing researchers to purchase compute nodes to be attached to the Legion cluster. This has been discontinued, as the Myriad cluster replaces the Legion cluster for the majority of users.

There are plans to allow the purchase of nodes for Myriad in future but these have not yet been finalised.
