Memory limit for the serial_long queue

Linux Cluster

The total memory a user can allocate on the serial_long queue of CoolMUC-4 will be limited to 100 GB (total of all running jobs) to avoid monopolization. Users with larger memory requirements are advised to use the teramem system. Newly submitted jobs will need to use the instruction #SBATCH --qos=cm4_serial_long. in the script. Failure will lead to the rejection

sbatch: error: Batch job submission failed: Invalid qos specification

This change will take effect July 6 10:00.

Kind regards
