Welcome to the QMUL HPC documentation site

This site supports the research computing services, including QMUL's High Performance Compute cluster, provided by the ITS Research group at Queen Mary University of London. It provides information on use, policy and best practices, alongside documentation for computing applications available on the cluster, to maximise cluster efficiency and total research output.


Apocrita is a heterogeneous HPC cluster comprising around 300 nodes and 7500 cores, managed by ITS Research at Queen Mary University of London for the primary purpose of supporting research performed by QMUL researchers. It is owned by QMUL and located in the Jisc shared data centre in Slough.


Why use Apocrita?

Using an HPC cluster can substantially reduce the time taken to compute problems by running analyses in parallel or breaking them up into pieces. Both strategies allow for the problem to be worked on by many separate compute cores (CPUs) at the same time.

The Apocrita system has been specifically designed to meet the needs of a wide variety of research in the areas of our three faculties: Humanities and Social Sciences, Science and Engineering, and Medicine and Dentistry.

Citing Apocrita in your research

Published research which has used the Apocrita HPC system should reference this facility using the following text:

This research utilised Queen Mary's Apocrita HPC facility, supported by QMUL Research-IT.

We also ask that you acknowledge assistance from ITS Research where applicable. Please see the citing page for examples.

Getting started

New cluster accounts for eligible users can be requested here. There are also sections on how to log in, change your password, submit a job, and a description of the various nodes available on the cluster.

There is also a current list of installed applications and how to use some of the more popular ones.

QMUL users can optionally request a Github only account, which provides access to QMUL's Github Enterprise instance but not to Apocrita.

ITS Research also provide support to some eligible users on Tier 2 HPC systems.
