Over the holiday period, we’re increasing queue limits to 10,000 jobs while reducing cluster capacity for energy savings. Normal operation resumes automatically on January 7, 2026.
NEMO2 has undergone a rolling upgrade with security, firmware/BIOS, and Slurm 25.05.5 updates. We planned and executed all steps to keep downtime for users as minimal as possible. Running jobs continued without interruption throughout the process.
FIDO2 SSH keys are now available on NEMO 2! Login with your Yubikey hardware token - no 2-factor unlock required. Keys work immediately after registration and provide enhanced security through hardware-protected authentication. Get started with our Quick Start Guide.
Automated snapshots of user home directories are now active. Recover accidentally deleted files with hourly, daily, and weekly snapshots.
Two new GPU nodes with 8× NVIDIA H200, 192 cores, 1.5 TB RAM, and 3.8 TB NVMe are now available in NEMO2 for testing via the “h200” partition. No software modules are installed yet.
NEMO2 has officially launched, transitioning from a testing phase to full production with expanded hardware, including AMD Instinct MI300A and Nvidia L40A nodes. NEMO1 is being phased out, with limited resources available until May 31st. Users are encouraged to transition to NEMO2 and consult the wiki for details.
NEMO2 uses Miniforge for conda environments, offering a streamlined setup with conda-forge as the default repository. The Miniforge module auto-initializes conda, simplifying environment activation without modifying shell profiles.
The AMD Genoa, Machine Learning and AI partitions for NEMO2 were delivered on December 4th. The acceptance of the storage has been delayed, so that NEMO2 could not yet start this year. However, calculations with the Milan nodes in NEMO1 are still possible.
