Slurm to be Upgraded to Version 23.11.4

OSC is preparing to update Slurm on its production systems to version 23.11.4 in preparation for the deployment of the new Cardinal cluster. This version of Slurm has a number of improvements, but it also has a known regression in behavior where if a job requests both a total number of tasks (--ntasks=N) and a number of tasks per node (--ntasks-per-node=n), the number of tasks per node takes precedence. OSC users are strongly encouraged to review their job scripts for jobs that request both --ntasks and --ntasks-per-node. Jobs should request either --ntasks or --ntasks-per-node, not both.

OSC Classroom Support

CLASSROOM RESOURCES FOR DISTANCE LEARNING If your class has lost or limited access to computer labs, the Ohio Supercomputer Center might be able to help by providing no-cost access to cloud computing resources. Classes and workloads of any size can gain access. OSC's web-browser interface to its substantial Linux computer systems provides novice users with virtual desktops preloaded with applications, such as MATLAB, RStudio, or Jupyter Notebook. As an example, an OSU undergrad statistics class recently used iPads to remotely access RStudio on OSC systems.
