IDRIS is organizing an online HPC and AI GPU profiling Bootcamp on February 10th, together with NVIDIA and the OpenACC organization.
This bootcamp provides an overview of profiling and code optimization on GPU through a mix of lectures and hands-on sessions which will in particular allow you to familiarize yourself with the NVIDIA profiling tools Nsight Systems and Nsight Compute. There will be two parallel hands-on sessions, one focusing on optimizing high performance computing codes and the other on optimizing artificial intelligence codes.
The hands-on sessions will take place on computing resources provided by NVIDIA. You can attend the bootcamp even if you do not have an IDRIS account.
The bootcamp will also be the occasion to discover the new NVIDIA Grace Blackwell NVL72 architecture which powers the prototype machine DALIA recently installed at IDRIS.
Attendees will have the opportunity to discuss their real-world projects and codes with NVIDIA experts at the end of the event.
Attending this bootcamp is highly recommended for those interested in the GPU hackathon [http://www.idris.fr/eng/annonces/idris-gpu-hackathon-2026-eng.html] which will be held at IDRIS in May.
Please register on https://www.openhackathons.org/s/siteevent/a0CUP00003MjHIf2AN/se000457 (registration deadline: January 27th).
Hello,
A maintenance operation on the technical infrastructure of IDRIS will require the centre to be shut down completely on Tuesday 7 October. The Jean Zay machine will be unavailable all day. The return to production is planned for the evening.
User Support will be closed for this day. The website will remain accessible and you will be able to check the machine availability on the usual page: http://www.idris.fr/status.html.
We are sorry for any inconvenience this operation might cause.

Dear Jean Zay users,
On January 1, 2025, IDRIS joined the European large-scale AI Support Centre MINERVA: http://www.idris.fr/minerva.html
In this context, we invite you to take part in a survey on the needs of AI users, in order to better understand the expectations and challenges faced by the AI community using HPC resources such as Jean Zay.
Your feedback will help improve services, technical support, training programmes, and more.
The survey takes about 10 minutes to complete and is aimed at individual users, teams, and organisations alike.

Hello,
During tomorrow's maintenance (April 1st, 2025), the operating system of the Jean Zay supercomputer will be updated to Red Hat 9.4 (from 9.2 currently). This update aims to provide a recent software environment on Jean Zay.
This operating system version change should have a limited impact on your use of the machine. The majority of your executables should continue to work without any action on your part; in case of issues, we recommend that you try to recompile your codes.
The GNU compilers bundled with the operating system will be updated to version 11.4.1. The "gcc/11.3.1" module will become an alias for a new "gcc/11.4.1" module to ensure an easy transition.
In case of problems, contact the IDRIS Support.
Best regards, The IDRIS user support team
For the fifth consecutive year, IDRIS is organising, together with NVIDIA, a GPU HPC and AI Hackathon.
It will take place on 13 May (remotely) and from 20 to 22 May 2025 (on-site at IDRIS). The registration deadline is 4 March.
GPU Hackathons allow teams of three or four developers or researchers to improve the performance of their HPC or AI codes under the guidance of one or more mentors, who are experts in GPU programming and come from universities, national laboratories, computing centres, government institutions and manufacturers.
You do not need to be an IDRIS user to participate in this event, so feel free to share this message with your colleagues. You will have access to IDRIS's computing resources, allowing you to test your code on recent GPUs, including NVIDIA H100s.
For HPC projects, it could be an opportunity to start porting a code to GPU using OpenACC, OpenMP, Kokkos, GPU libraries, CUDA, etc., or to optimise an existing GPU implementation. If your codebase is large, it is recommended to prepare a representative mini-application to be more efficient during the event.
For AI projects, this hackathon offers a unique opportunity to explore fine-tuning, developing or evaluating state-of-the-art models such as LLMs and GenAI applications. You will be able to optimise your models using advanced techniques such as mixed precision, multi-GPU or multi-node parallelisation (DDP, PP, TP, CP), using standard frameworks such as PyTorch or TensorFlow, or specialised tools such as DeepSpeed, Megatron-LM, Nanotron or NVIDIA NeMo. Although full pre-training is out of reach within the hackathon's time frame, preparing a pre-training code for large-scale models is still possible.
Registration is via the event page (in English): https://www.openhackathons.org/s/siteevent/a0CUP00000sO9LV2A0/se000364.
Janine Connes, founder of the CNRS Inter-Regional Electronic Computing Centre (CIRCÉ) in 1969 and its director until 1982, passed away on 28 November 2024 at the age of 98. Together with her husband Pierre Connes, she formed a high-flying scientific duo, with Pierre as the experimenter and Janine processing and analysing the results numerically. This pair established the Fourier Transform Infrared Spectroscopy method, which is of major importance in this field. The page on the University of California Los Angeles website dedicated to Mrs Connes attests to this. She also played a crucial role in the development of numerical simulation in France, enabling the CNRS to acquire the necessary resources to serve all scientific communities. She provides a detailed account of this saga in her book From the IBM 360/75 to the Jean Zay Supercomputer, written with the participation of Françoise Perriquet and published in 2022[^1]. We will briefly recall only the premises and the main stages here.
Deepmind has open-sourced Alphafold 3 and made it available on GitHub. However, the model weights are subject to a licence that makes it impossible to provide them to all IDRIS users.
https://github.com/google-deepmind/alphafold3/blob/main/WEIGHTS_TERMS_OF_USE.md
Indeed, a number of people using IDRIS resources are not part of the academic world.
We will contact Deepmind to see if it is possible in our situation to share the weights. While waiting for a response, we will apply the following procedure:
We have requested the model weights to perform internal tests.
Once these tests are completed, we will publish documentation on the website with all the steps to run Alphafold 3.
This post provides an overview of the ongoing operations for the commissioning of the Jean Zay H100 extension. The information provided here will evolve over time, and we invite you to check back regularly.
