Science behind the Image Competition
Webinar today Wednesday 8th November 2023 14:00 GMT
In this webinar we invite entrants from the 2023 ARCHER2 Image and Video Competition to talk about their work, and the science behind their stunning images and videos.
This online session is open to all. It will use the Blackboard Collaborate platform.
ARCHER2 Celebration of Science
We are pleased to announce that the ARCHER2 Celebration of Science will take place on the 7th – 8th March 2024 in Edinburgh at South Hall, The University of Edinburgh.
The event will provide ARCHER2 users with the opportunity to showcase their science achievements on ARCHER2. The two-day programme will include a variety of talks from members of the ARCHER2 research consortia and other invited presenters involved in the ARCHER2 service, a poster session and a panel session focusing on preparing the UK science community for future Exascale systems. All attendees are welcome to join the drink reception on the evening of the first day.
The event is in-person and there is no registration fee.
ARCHER2 Calendar 2024 - sign up for your copy
Sign up for your copy of the ARCHER2 Calendar 2024 and it will be posted straight to your desk.
Access to HPC call open
EPSRC Access to HPC call is open, with the deadline for submission of TAs being 17 November 2023 16:00, and the closing date for applications is 1 December 2023 16:00.
Details including the Technical Assessment form can be found on our Access page

ARCHER2 User Survey 2023
We are committed to continually improving the ARCHER2 Service and would like to request your input to help us understand what is important to you, where the Service is working well and where there is scope for improvement.
The ARCHER2 Annual User Survey consists of just a few questions and should take only a few minutes of your time to complete. There are opportunities to add more detailed comments if you wish.
For each survey response received, we will donate £1 to Save The Children.
Thank you in advance for taking the time to complete this survey. The responses will be used to try and improve the service for you and to help identify key areas for service development.
Single Node Performance Optimisation
Online, 23 - 24 November 2023 09:30 - 16:30 GMT
This course covers techniques for improving the performance of parallel applications by optimising of the code that runs within each node.
Modern HPC systems such as ARCHER2 are being constructed using increasingly powerful nodes, with larger and larger numbers of cores and enhanced vector capabilities. To extract maximum performance from applications, it is therefore necessary to understand, and be able to overcome, on-node performance bottlenecks. This course will cover the main features of modern HPC nodes, including multiple cores, vector floating point units, deep cache hierarchies, and NUMA memory systems. We will cover techniques for efficient programming of these features, using batch processing options and compiler options as well as hand tuning of code. The course will also contain an introduction to the use of Cray performance analysis tools.
Participants must have attended ARCHER2 for Software Developers or be familiar with software development on ARCHER, ARCHER2, or any other HPC facility, using C, C++ or Fortran.
This course is targeted at users interested in optimising the performance of their own applications, e.g. through compiler options or code changes.
Users interested in efficient use of centrally installed packages should consider attending Understanding Package Performance instead
ARCHER2 for Package Users
Online, 7 December 2023 09:30 - 15:30 GMT
This lesson provides an introduction to using ARCHER2 for users who:
- have already used other HPC systems; and
- want to use pre-installed simulation/modelling packages rather than compiling their own.
The lesson aims to answer the following questions:
- What hardware is available on ARCHER2?
- What does it consist of (login nodes, compute nodes, file systems, backup)?
- How does this impact me as a user?
- How can I access ARCHER2 interactively and transfer data?
- What does the ARCHER2 software environment look like and how do I access software?
- How do I write job submission scripts and submit them to the ARCHER2 scheduler?
- How can I be a good ARCHER2 citizen?
- How can I check what resources I am using and look at historical usage?
- What are the next steps for me using ARCHER2 and how can I get more help?
