Exhibits and Engagement Activities for the ARCHER2 Celebration of Science 2025

We are looking for exhibits and/or activities to participate in the ARCHER2 Celebration of Science 2025 on the 14th - 15th May 2025 in Edinburgh at South Hall, The University of Edinburgh. These exhibits/activities will be in the main foyer area of the event and attendees will be able to engage with these throughout the event. These exhibits may for example showcase your outreach activities aimed at the general public or showcase dissemination activities for fellow professionals. These do not need to be on a large scale, our aim is to highlight a diverse range of activities.

If you are interested in showcasing your activities at the event please email events@archer2.ac.uk to discuss.

ARCHER2 Celebration of Science 2025 - Poster Abstract Submission Due by Friday 21 March

Following the success of ARCHER2 Celebration of Science 2024, we are pleased to announce that ARCHER2 Celebration of Science 2025 will take place on the 14th - 15th May 2025 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 ARCHER2 researchers and other invited presenters involved in the ARCHER2 service, a poster session and a panel session.

The event is in-person and there is no registration fee.

We would like to invite the ARCHER2 community to submit posters for presentation at the ARCHER2 Celebration of Science 2025. Posters should demonstrate your work on ARCHER2, showcasing the science outcomes and impact achieved. Please complete the Poster Abstract Submission Form and email it to events@archer2.ac.uk by Friday 21st March 2025.

GPU programming with HIP

Online, 24 - 26 March 2025 10:00 - 16:00

This three-day course will provide an introduction to GPU computing with HIP aimed at scientific application programmers wishing to develop their own software. The course will give a background on the difference between CPU and GPU architectures as a prelude to introductory exercises in HIP programming. The course will discuss the execution of kernels, memory management, among other topics.

The course will not discuss programming with compiler directives, but does provide a concrete basis of understanding of the underlying principles of the HIP model which is useful for programmers ultimately wishing to make use of OpenMP or OpenACC. The course will not consider graphics programming, nor will it consider machine learning packages.

Note that the course is also appropriate for those wishing to use NVIDIA GPUs via the CUDA API, although we will not specifically use CUDA.

Introduction to Modern Fortran

Imperial College London, 24 - 25 March 2025 09:30 - 16:30 GMT

This course is aimed at users and developers who know how to program, but have little or no experience in Fortran, and those who may wish to have a refresher in Fortran.

Fortran (a contraction of Formula Translation) was the first programming language to have a standard (in 1954), but has changed significantly over the years. More recent standards (the latest being Fortran 2023) come under the umbrella term “Modern Fortran”. Fortran retains very great significance in many areas of scientific and numerical computing, particularly for applications such as quantum chemistry, plasmas, and in numerical weather prediction and climate models.

This course provides an introduction to the basics of writing Fortran. It will cover basic syntax, variables, expressions and assignments, flow of control, and introductions to i/o and user-defined types. Common Fortran idioms are introduced and contrasted with those available in C-like languages; the course will try to focus on real usage rather than formal descriptions.

At the end of the course you should be able to understand many Fortran programs and be confident to start to write well-structured and portable Fortran. Fortran is a rather “large” language, so it is not possible to cover all its features in a two day course. Further elements of Fortran are discussed in the “Intermediate Modern Fortran” course. Prerequisites:

Attendees must be familiar with the basic concepts of programming: variables, logic, flow of control, loops, functions and so on. No knowledge of Fortran is assumed. Previous programming experience might typically be in the context C/C++ or python. If you know no programming, we suggest this course on Fortran is not the place to start.

The course requires a Fortran compiler, for which a local machine or laptop may be appropriate [1]. If you do not have access to a Fortran compiler, course training accounts on ARCHER2 will be available which provide access to various compilers. Use of a text editor will be required (some may prefer an IDE, but we do not intend to consider or support IDEs).

[1] This may typically be gfortran, freely available as part of Gnu Compiler Collection (GCC). See e.g., https://gcc.gnu.org/wiki/GFortranBinaries

Modern C++ for Computational Scientists

Durham, 23 - 24 April 2025 09:30 - 16:00

With the recent revisions to the C++ language and standard library, the ways it is now being used are quite different. Used well, these features enable the programmer to write elegant, reusable and portable code that runs efficiently on a variety of architectures.

However it is still a very large and complex tool. This course will cover a minimal set of features to allow an experienced non-C++ programmer to get to grips with language.

These include:

  • overloading
  • templates
  • containers
  • iterators
  • lambdas
  • standard algorithms

We will also briefly cover some important libraries for numerical computing.

AMD MI300 Series Hackathon : Registration deadline 31 March 2025

Edinburgh, 27 - 29 May 2025 10:00 - 16:00 BST

ARCHER2 and AMD are hosting a three-day in-person hackathon to explore the potential of AMD GPUs for research. The event will focus on porting and optimizing code using the latest AMD development suite. This event is ideal for both expert practitioners and less experienced users who want to convert CPU-focused codes into efficient GPU-ready applications, and enhance the performance of current GPU-based codes using AMD’s next-gen MI300x GPU cards or the new MI300A APU superchip.

We’re looking for teams of 2-5 members. Participants will work with AMD experts and have access to AMD resources. In-house experts from the ARCHER2 team are also on hand.

Deadline for applications is on 31st March 2025. Full details and registration Limited spaces: Applications will be reviewed as received, so early submission increases your chances.
