⚠️ January System Updates - 2023/01/01

Beginning January 23, 2023, the MARC cluster will undergo operating system updates. We shall do our utmost to minimize disruption and allow ongoing jobs to be completed. New jobs may be temporarily held from scheduling.

Thank you for your cooperation.

System Updates Completed - 2023/01/24

The upgrade has been completed. The following has been changed:
  • OS Updated to Rocky Linux 8.7
  • Slurm updated to 22.05.7
  • Apptainer replaces Singularity
  • Each job will have its own /tmp, /dev/shm, /run/user/$uid mounted

If you encounter any system issues, do not hesitate to let us know.

Thank you for your cooperation.


Apptainer (Singularity) on MARC Login Node - 2023/06/23

Apptainer (Singularity) containers may experience an error when

running on the MARC login node. If apptainer complains that a system administrator needs to enable user namespaces, simply run your containers inside a job.

This is a temporary measure due to security vulnerability that will be

patched soon.

We will be performing storage upgrades on the MARC/ARC cluster on
