Computing resources

L2S has access to the Saclay-IA and Moulon regional computing platforms and to the national Jean Zay facility. These resources are hosted at IDRIS, the CNRS national computing centre.

Computing platforms

• Saclay-IA / Lab-IA: GPU computing nodes.
• Moulon / Ruche: CPU and GPU resources, including MATLAB licences.
• Jean Zay: a national facility operated under GENCI, particularly for AI, with more than 1,500 CPU nodes (over 60,000 cores) and nearly 300 GPU nodes. AI users can apply through the dynamic access procedure on eDARI.

VirtualData

Université Paris-Saclay also provides access to VirtualData at IJCLab in Orsay. Cloud@VD provides virtual machines for lighter workloads, with working environments such as Ubuntu and Windows. VirtualData also offers bare-metal hosting with attention to energy consumption and cooling.

L2S computing users mailing list

l2s.utilisateurs.mesocentre@listes.centralesupelec.fr

• Information about the facilities and guidance on access.
• Feedback on user needs and problems to the technical committees.
• News and training opportunities.
• Information on project charging and acknowledgement in publications, including publications and challenges using the facilities.

Subscription is automatic when an account is opened on a regional computing facility. Alternatively, email sympa@listes.centralesupelec.fr with the subject subscribe l2s.utilisateurs.mesocentre Firstname LASTNAME.

Use and training

Access is through SSH and jobs are submitted using SLURM. Training sessions for Lab-IA and Ruche are organised regularly; questions can be raised on the user mailing lists.

SSH gateway

Access to Lab-IA and Jean Zay uses sshgw.centralesupelec.fr.

1. Create a public/private SSH key pair, the authentication method used by the gateway.
2. Register the public key on MySchool Research and note the gateway username shown there.
3. Ask l2s.informatique@centralesupelec.fr to add you to the laboratory PASS SSH team through MyAdmin.

For Jean Zay, an additional form signed by the user and the CentraleSupélec information security officer is needed to register the access machine. Send it to informatique@centralesupelec.fr. Use the “Ajout, modification ou suppression de machines” section of the IDRIS form.
