• NEW IDRIS website

Following a long collaborative effort, IDRIS has redesigned its website. The address http://www.idris.fr will remain unchanged. Therefore, do not be surprised when this new site becomes accessible (normally by the end of the month).

• Next IDRIS UC meeting: Tuesday 31 March 2026

The next meeting of the IDRIS User Committee (UC) will take place on Tuesday 31 March 2026 at the IDRIS premises. Do not hesitate to send your requests to the address cu-elus at idris.fr before Tuesday 24 March 2026. More information: http://www.idris.fr/cu.html

• idr_module_search command

For those who use the conda environments provided by IDRIS, a new command "idr_module_search" has been developed to help you find the most suitable Jean Zay module for your needs. It allows you to identify which environments contain certain packages, with or without version specification. For more information: http://www.idris.fr/jean-zay/gpu/jean-zay-gpu-logiciels-ia.html#%F0%9F%94%8D_commande_idr_module_search

• Reminder on the proper use of Jean Zay file systems

We remind you that it is recommended not to exceed a few tens of thousands of elements (files and subdirectories) per directory to ensure the proper functioning of Jean Zay's file systems. If you have a very large number of files to store, adjust the depth of your directory trees accordingly. Following this rule will also ensure the best possible performance, as metadata can be efficiently distributed among the different storage servers.

• Misuse of squeue

We remind you that misuse of the "squeue" command can contribute to overloading the Slurm job manager. We invite you to limit the number of calls to "squeue" to a maximum of one or two per minute if you use a script to monitor the status of your jobs. Since Slurm's internal refresh rate is of the same order of magnitude, there is no point in making more frequent requests.

For the sixth consecutive year, IDRIS is organising, in conjunction with NVIDIA, a GPU HPC and AI Hackathon.

It will take place on May 12th (remotely) and from May 19th to 21st 2026 (at the IDRIS premises). The registration deadline is set for March 10th.

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, governmental institutions, and manufacturers.

It is not necessary to be a user of IDRIS to participate in this event, so feel free to share this message with your colleagues. You will have the opportunity to access IDRIS's computing resources to test your code on recent GPUs, including NVIDIA H100s on Jean Zay and NVIDIA GB200 NVL72s on the DALIA prototype machine.

For HPC projects, it could be a matter of starting to port a code to GPU using OpenACC, OpenMP, Kokkos, GPU libraries, CUDA, etc., or optimising an existing GPU implementation. For large codebases, 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 can optimise your models using advanced techniques such as mixed precision, multi-GPU or multi-node parallelisation (DDP, PP, TP, CP), using basic 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 timeframe, preparing a pre-training code for large-scale models is still possible.

Registration is done via the event page (in English): https://www.openhackathons.org/s/siteevent/a0CUP00003Ahxc22AB/se000449.

Hello,

During yesterday's maintenance (February 17th, 2026), the operating system of the Jean Zay supercomputer has been updated to Red Hat 9.6 (from 9.4 previously). This update aims at keeping a recent software environment available 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, however in case of issues we recommend that you try to recompile your codes.

The GNU compilers bundled with the operating system have been updated to version 11.5.0. The "gcc/11.4.1" module is now an alias for a new "gcc/11.5.0" module in order to ensure an easy transition.

In case of problems, contact the IDRIS support.

Best regards, The IDRIS user support team

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).

• Reminder: Survey on AI user needs within the MINERVA project

Since 1 January 2025, IDRIS has joined the European large-scale AI support centre MINERVA: http://www.idris.fr/minerva.html. As part of this, a survey is underway to better understand the expectations and challenges faced by the AI community using HPC resources such as Jean Zay. Your contribution is valuable to help us evolve services, technical support, training programmes, etc. Link to the survey: https://docs.google.com/forms/d/e/1FAIpQLSeWdowBcyc1d9bMsh6BGcolZQj_pECPpoCsF9Mdyf60Fcr68w/viewform?usp=header.

• New compilation partition "compil_H100"

A new partition "compil_H100" is available to users: http://www.idris.fr/jean-zay/cpu/jean-zay-cpu-hw.html#compil_H100. It contains a node equipped with an Intel processor identical to those in the Eviden H100 partition (gpu_p6). It is dedicated to the compilation of codes and libraries that will run on this partition. It has the same access characteristics as the "compil" partition.

• Blocking GitHub usage via SSH from Jean Zay

To standardise Git behaviour and for security reasons, access to GitHub via the SSH protocol will be completely blocked on all IDRIS machines from 15 September 2025. Until now, some GitHub SSH access points were whitelisted, which resulted in variable behaviour depending on the connections (some allowing access, others not). This situation could be confusing. From now on, only the use of the HTTPS protocol with personal token authentication will be allowed to interact with GitHub (cloning, push, pull, etc.). 👉 To generate a GitHub token and configure your repository in HTTPS: https://docs.github.com/fr/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token Please anticipate this change by adapting your Git configurations before 15 September 2025.

• DSDIR saturation: Migration of text corpora to rotating disks

During the summer, we reached saturation of the shared DSDIR space, which contains the public datasets and models that we download on request. To free up space, we have moved the CommonCrawl and RedPajama-V2 text corpora to an annex storage space on rotating disks. From now on, any text corpus will also be stored on rotating disks. The access paths to these datasets remain unchanged: $DSDIR/<nom_du_dataset>. According to the tests we have carried out, this should not impact the performance of your training. Please contact support (assist at idris.fr) if this is the case.
