DiRAC 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 for each DiRAC service machine in person as well as to interact with the industry vendors who supplied the hardware we are now exploiting.

Dirac Day COC

Code of Conduct

DiRAC is committed to creating a work environment that is safe, professional and of mutual trust where diversity and inclusion are valued, and where everyone is entitled to be treated with courtesy and respect. DiRAC is committed to making DiRAC Day and all associated activities safe and professional environments for everyone. We will not tolerate harassment of participants in any form.

Please follow these guidelines:

1. Behave professionally. Harassment and sexist, racist, or exclusionary comments or jokes are not appropriate. Harassment includes sustained disruption of talks or other events, inappropriate physical contact, sexual attention or innuendo, deliberate intimidation, stalking, and photography or recording of an individual without consent. It also includes offensive comments related to individual characteristics, for example: age, gender, sexual orientation, disability, physical appearance, race, nationality or religion.

2. All communication should be appropriate for a professional audience including people of many different backgrounds. Sexual or sexist language and imagery is not appropriate.

3. Be respectful and do not insult or put down other attendees or facilitators of the event. Critique ideas not people.

4. Should a participant witness events of bullying, harassment or aggression, we recommend that they approach the affected person to show support and check how they are. The witness may also wish to suggest that the person report the inappropriate behaviour. However, it is up to the affected person alone whether or not they wish to report it.

5. If participants wish to share photos of a speaker on social media, we strongly recommend that they first get the speaker’s permission. Participants may also share the contents of talks/slides via social media unless speakers have asked that specific details/slides not be shared.

The DiRAC Day Local Organising Committee has two members who are designated as the contact points for all matters related to this code. These members are Mark Wilkinson and Rebecca Nealon. Participants can report any violation of these guidelines to these designates in confidence. If asked to stop inappropriate behaviour participants are expected to comply immediately and, in serious cases, may be asked to leave the event without a refund. DiRAC will not tolerate retaliation against anyone reporting violations of this code of conduct.

Thank you for helping to make DiRAC Day welcoming for all.

Dirac Day Hackathon

ARM Mellanox Hackathon

From 9th-11th September (immediately before DiRAC Day on Sept 12th), DiRAC are pleased to be hosting a hackathon at Leicester focussed on two novel technologies:

  1. Arm processors – use the HPE/Suse/Arm Catalyst UK cluster hosted at Leicester, to explore whether your code can benefit from the enhanced memory bandwidth offered by the Thunder X2 processors. In addition, codes which are found to perform well on Arm cores will be able to access (potentially significant amounts of) time on this 4096-core cluster at Leicester in the period before it is handed over to the DiRAC RAC and the University of Leicester to go into full production.
  1. Mellanox Bluefield – explore the potential benefits of offloading parts of your science calculations onto the additional compute capacity available within the next generation of network switches. 

Technical experts from both Arm and Mellanox will be attending to provide assistance and advice on porting your code and/or modifying it to take advantage of the new hardware.  DiRAC users who have attended previous hackathons have found them to be very productive, providing an opportunity to benefit from the expertise of colleagues around DiRAC as well as from the industry partners.

If you would like to attend, please complete the application form.

The deadline for applications is 10am on Monday, 22nd July.

We are very grateful to both Arm and Mellanox for sponsoring this event which means that attendance will be free of charge, and we will be able to contribute towards accommodation costs of attendees.

If you have any questions, please do not hesitate to contact either Richard Regan (DiRAC Training Manager; richard.regan@durham.ac.uk) or Mark Wilkinson (miw6@leicester.ac.uk).
