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).
The IDRIS helpdesk will be exceptionally closed on Wednesday 24 December, Friday 26 December and Monday 29 December 2025. Requests sent to assist at idris.fr will only be processed from Tuesday 30 December. The administrative management service for users remains open on these dates, so you can contact gestutil at idris.fr for any request related to the management of your computing account (password reset, addition of a connection IP address, etc.).
The next meeting of the IDRIS User Committee (UC) will take place on Thursday 18 December 2025 at the IDRIS premises. Do not hesitate to send your requests to the address cu-elus at idris.fr before Friday 12 December 2025. More information: http://www.idris.fr/cu.html
Remember to register now for the IDRIS training sessions scheduled until next summer:

CC-FR Webinar to Discover MINERVA: 4 December 2025 at 2 PM
IDRIS Training
On Thursday 4 December 2025 at 2 PM, the French Competence Centre (CC-FR) invites you to a webinar open to all to discover MINERVA, the European centre for services dedicated to large-scale AI on supercomputers. Mathieu Lobet (CEA / Maison de la Simulation) will present how MINERVA supports researchers, engineers and companies in bringing their AI workflows to HPC infrastructures, optimising their models at scale and leveraging EuroHPC resources for their AI projects. Come and discover how to benefit from MINERVA support and discuss your AI and HPC needs! All information and the registration procedure are available here: https://cc-fr.eu/%C3%A9v%C3%A8nement/accelerez-vos-projets-dia-a-grande-echelle-avec-minerva-le-centre-europeen-dedie-a-lia-sur-supercalculateurs/.
The following IDRIS training sessions are confirmed and will take place before the end of the year:

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.
Best regards, The IDRIS User Support Team
The next User Committee (UC) meeting of IDRIS will take place on Wednesday 10 September 2025 at the IDRIS premises in Orsay (91). Please send your requests to: cu-elus at idris.fr. More information: http://www.idris.fr/cu.html
The annual maintenance of the IDRIS technical infrastructure requires the shutdown of the centre on Tuesday 7 October 2025. The Jean Zay machine will be unavailable all day and the User Support service will be closed. The website will remain accessible and you can follow the availability of the machines on the usual page: http://www.idris.fr/statut.html.
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.
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.
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.
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.

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
