JUPITER

EESSI, the base of the EFP Federated Software Catalog, is available system-wide on JUPITER via a native CernVM-FS deployment since April 2026.

Synchronisation

JUPITER is synchronised daily with the public EESSI infrastructure. This means that once new software has been integrated into EESSI, the maximum wait time for it to appear on the system is 24 hours.

Access

Standard access instructions apply.

Usage

EESSI is available by default on both login and compute nodes but requires initialisation. See the initialisation instructions for the Federated Software Catalog and then continue with loading your required software.

Known problems and limitations

No known limitations.

System-specific best practices

Multi-node jobs
