Resource Allocation Committee

DiRAC makes an annual Call for Proposals and the Resource Allocation Committee (RAC) was established by the STFC to oversee time allocation.  The RAC has two sub-panels, one for Particle Physics & Nuclear Physics and one for Astronomy and Cosmology, each of which consider the proposals within their respective remits.

A RAC meeting with representatives from both sub-panels then determines the overall allocation of DiRAC time across the whole portfolio of proposals.

Together their research addresses all the STFC Science Challenges. The featured photo in the header above shows the CSD3 Peta4 CPU/KNL cluster which provides our Data Intensive@Cambridge Service.

The Current Call for Proposals (10th) Closed on 14th November 2017, and the allocations started on the 1st May 2018. The awards from the 10th Call are available here.

The Next Call (11th) will open in June 2018, Close on 1st October 2018 and Allocations awarded will begin on 1st May 2019.


Call Results: Compute Time and Storage Allocated

After each  Call has been concluded, we publish the compute time allocated to each project, in terms of CPU-Mhours on the DiRAC Resource on which the calculations are to be run, as well as the Storage Space [TB] allocated. In DiRAC we have three compute services and due to the different architectures on each Service, the CPU-Mhours awarded to projects using different services may not be directly comprable.

User Accounts

Projects and accounts on DiRAC resources are administered through the DiRAC SAFE. SAFE stands for Service Administration From EPCC. It is a large web-based application, provided by EPCC for DiRAC. The same software is used by the Archer UK national supercomputing service and for other facilities at EPCC.

Every DiRAC user has an account on SAFE. You can use your SAFE account to check your use of CPU time and disk space now and in the past, to apply to join other projects and create service machine accounts, to change passwords, to keep your personal details up to date, to check the progress of the helpdesk queries you have submitted, and so on. PIs and project managers can do many other things. such as viewing usage by each member of their project team.

The DiRAC team also uses SAFE to administer the system and to generate reports. The helpdesk software is also part of SAFE. If you are a PI or project manager you can manage your project via SAFE.

You can find all the information you need on SAFE here. For any other information please email DiRAC Support.

Call for Proposals

Access to DiRAC is co-ordinated by The STFC’s DiRAC Resource Allocation Committee, which puts out an annual Call for Full Proposals to request time and operates a Seedcorn Time programme for small requests.


Director’s Discretionary Proposals

This Call is now closed.

The DiRAC Director invites the UK theory and modelling communities in Astrophysics, Particle Physics and Nuclear Physics to apply for Director’s Discretionary Proposals for computational resources on the STFC DiRAC HPC Facility. 

More information can be found here.


Seedcorn Time

More information on our Seedcorn Time programme can be found here.


Full Call for Proposals

For each Full Call for Proposals the RAC produces a set of documentation that includes a number of forms that every applicant must complete. They also provide a comprehensive set of guidance notes.

11th Call for Full Applications (current call)

The 11th Call opened on the 9th July 2018. The Call will close on the 1st October 2018 and allocations will begin on 1st April 2019. Key dates for the STFC’s internal processing of applications will be posted here later in the summer.

The RAC publishes a new set of documentation for each Call and the Announcement, Forms and Guidance Notes for the 11th Call are below.

Please note that the submission address for the Technical Assessment Form has changed since the forms were first posted on the 9th of July. The submission address is now:
dirac-support@epcc.ed.ac.uk.

The submission address for all other documentation, including the Call Application Form & RSE Request Form, has not changed and remains: DiRACRAC@stfc.ac.uk

The Key Changes implemented in the 11th Call include:

  • Applicants must have submitted and discussed a technical assessment (per proposal) with the DiRAC TWG;
  • Applicants will only be considered if this has been initiated a month before the closing date of 1st October 2018 (i.e. the technical assessment must be submitted by 1st September 2018).
  • No single application can request more than 80% of the availability of a DiRAC machine within a given year;
  • Currently existing Thematic proposals can submit proposals with the following options;
    • Applications with scientific themes distinct from the existing award can be submitted as a separate proposal.
    • Applications building on the same scientific theme as an existing award should apply as a new project, this new award would then replace any existing compute award. Applications in this category are expected to be observed if significant new resources become available which would greatly effect a project, or if significant scientific developments warrant a project update. PI’s requesting for a revised or updated long project must justify this request fully; the RAC will take into account all currently active projects which hold a comparable science case. This method cannot be used to top-up an existing project award if there is no change in the science case.
    • The application and scoring matrix has been updated to include a strong emphasis on Project Management and Data Management Plans;
    • Research Software Engingeering Request Forms should be submitted with the Call Application Form, on or before the Call Closing date of 1st October.
  • The above changes and a number of smaller changes have been implemented and can be seen in the revised RAC 11th Call Guidance Notes.

10th Call Application Documentation (closed)

The 10th Call for Proposals closed on 14th November 2017 and the allocations started on the 1st May 2018. The awards from the 10th Call are available here.

The forms and guidance from the 10th Call for Proposals (closed) are below. The RAC publishes a new set of documentation for each call.


For help with application queries please contact the DiRAC Director: Dr Mark Wilkinson and/or the DiRAC Technical Director: Professor Peter Boyle.

DiRAC Day

8th Annual DiRAC Science Day
12th September 2018
Swansea University

On September 12th, Swansea University will host the 8th Annual DiRAC Science Day. The day provides an opportunity to meet others from the DiRAC HPC community, learn about what is being done by all the different consortia, present and view posters on recent research achievements and discuss training and support needs for DiRAC. DiRAC users will also have the chance to meet members of the technical support teams in person as well as interact with the industry vendors who supplied the hardware we are now exploiting.

All attendees are encouraged to bring a poster to present (subject to space availability). There will be two prizes awarded to the posters by students or PDRAs judged to be ‘the best’.

Registration for DiRAC Day is via Swansea University’s dedicated DiRAC Day website, where you can also find a link to Accommodation Booking on the Swansea University campus.


This year there are three other interesting events being held at Swansea University which co-incide with DiRAC Day….


Co-located Events
NVidia Hackathon
9th, 10th & 11th September

DiRAC is pleased to announce that Nvidia have generously agreed to sponsor a 3-day GPU hackathon in Swansea prior to DiRAC Day 2018. This event will provide the DiRAC community with the opportunity to explore the potential for GPUs in supporting their science.

The Hackathon is open to all DiRAC HPC users and we expect to be able to offer places to 5 or 6 teams of between 3 and 5 people each. Over the three days, we hope that several major DiRAC science codes will be ported to GPUs and that the teams who attend will gain the skills to assist other DiRAC researchers to port additional codes in the future.

More information, including the application form can be found here.


Hands-on Introduction to Data Visualisation
13th & 14th September

Swansea University are hosting a stand-alone training course on Data Visualisation to run on the 13th and 14th September. The event will provide delegates with a concise introduction to the art and science of applied data visualisation.

More information on this course can be found here.


SuperComputing Wales Research Symposium 2018
13th September

The Swansea Academy of Advanced Computing are bringing together the Supercomputing Wales community to give users a forum to showcase their research to the wider HPC community and network with other supercomputing specialists.

The event will include research talks, a poster session, and opportunities for discussion about the Supercomputing Wales project and SUNBIRD machine.

DiRAC Training All Levels

The DiRAC Training Program
At DiRAC, we believe one of the facility’s most important responsibilities is to offer its user-base comprehensive training.  A well-trained user-base increases the volume and complexity of research that can be carried out and means we can use systems that are closer to the edge of technology, which in turn means that more and better research can be carried out.  

The DiRAC training program has been designed to guide users along a path from very little knowledge to a really good understanding of HPC code development. We recognise that our users predominantly fall into two categories: those who run existing codes, and those that develop and enhance codes, so we have broken up the training into 5 levels of increasingly advanced content.

We do not expect all users to complete the whole program but we do require all new users with less than 2 year’s experience to complete Level 1: Essentials, and the accompanying on-line test by the end of their first year. The program as a whole has been designed so that all new users of HPC systems would benefit from the first three levels, with researchers involved in code development progressing beyond Level 3 as an when the content becomes useful to their Research.

Each level has a corresponding body of material associated with it and currently these resources are sourced from academic institutions and the general IT community. We are still in the process of populating Levels 2 – 5 but we expect these to come on-line as the year progresses

  1. DiRAC – Essentials: An introduction to the key skills needed when using the UK National DiRAC HPC Service and a building block for the further levels.

  2. DiRAC – Researcher: This level will give users the skills to run codes on any DiRAC system.

  3. DiRAC – Advanced Researcher: This level tackles the challenges of replicating another code or advancing your own.

  4. DiRAC – HPC Developer: This level provides the skills needed to start creating robust, well structured and efficient code.

  5. DiRAC – Expert Practitioner: This will enable users to use these codes as efficiently as possible.
