HORUS / OSiRIS update — new lg nodes, Ceph upgrade, and service reminder
Just two quick announcements.
1) We have added 7 new nodes to the HORUS SLURM cluster. These are large memory and large CPU hosts (1.5 TB of RAM, 384 logical CPUs, 2x100Gbps network) and are part of a new SLURM partition named ‘lg’. 2) We are updating the OSiRIS Ceph from 18.2.4 to 19.2.1.
A reminder: we are running the infrastructure in a best-effort way until August 2026. For users that have a lot of data in OSiRIS, it may be worthwhile to start planning where it will go after August 2026.
Please consider deleting data you no longer need or use.
If you have any questions or concerns, you can contact us at horus-help ‘at’ umich.edu.
