Exploding, forming and disentangling stars with HPC

Online webinar, Wednesday 10th March 2021 15:00 - 16:00 BST

High-performance computation (HPC) is central to modern astronomy. Moreover, the diversity of astronomy as a science results in models with very different computational requirements.

In this presentation, I will show-case three representative astrophysical problems which strongly rely on HPC in different ways. These include the models of how mergers of white dwarf stars may lead to type 1a supernovae, which are among the brightest explosions in the universe; simulations of binary stars with a detailed stellar evolution code, which demonstrate how these stars trace the history of our Galaxy; and finally, the evolution of triple stars, for which using correct models of stellar interactions make a substantial effect on their present-day orbits.

This online session is open to all. It will use the Blackboard Collaborate platform.

Access to HPC call open

The Access to High Performance Computing Call, through which EPSRC users can access the council’s new and upcoming Tier-1 and Tier-2 resources has now gone live:

This call is the successor to the ARCHER RAP and Tier-2 Open Access calls processes, through which users were previously able to access each of EPSRC’s HPC resources.

EPCC GPU Hackathon 19-28 April 2021

Deadline for Applications extended to 5th March 2021

EPCC will host a virtual GPU Hackathon and we invite applications from teams of three to six developers to take part.

The EPCC GPU Hackathon is a multi-day event designed to help teams of three to six developers accelerate their own codes on GPUs using a programming model, or machine learning framework of their choice. Each team is assigned mentors for the duration of the event and provides an exciting opportunity for scientists to accelerate their AI research or HPC codes under the guidance of expert mentors from National Labs, Universities and Industry leaders in a collaborative environment.


  • Teams are expected to be fluent with the code or project they bring to the event and motivated to make progress during the Hackathon.
  • No advanced GPU skills required, but teams are expected to know the basics of GPU programming and profiling at the event. A collection of GPU lectures, tutorials, and labs are available for all participants at no no fee (see: Please contact organisers for more information to help you prepare for the hackathon.

GPU Compute Resource:
Teams attending the event will be given access to the GPU nodes on Cirrus ( for the duration of the Hackathon. If participants prefer they can use their own GPU resource at the event.

Further details can be found at: or please contact if you have any questions.
