- Next IDRIS UC meeting: Wednesday 10 September 2025
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
- Technical shutdown on 7 October 2025
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.
- 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.
