Pitzer

Vulnerability in R Programming language

A vulnerability, CVE-2024-27322, in the R programming language that affects the serialization and deserialization process in the R programming language prior to version 4.4.0 is discovered. This vulnerability can be exploited through R Data Serialization (RDS) files or R packages, which are often shared between developers and data scientists. R addresses the vulnerability starting from version 4.4.0. We have installed R 4.4.0 on all clusters and recommend using R/4.4.0. Please limit package use to trusted sources.

System Downtime May 7 2024

A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, May 7 2024. The downtime will affect the Pitzer, Owens and Ascend Clusters, web portals, and HPC file servers. The state-wide licenses and MyOSC (the client portal) will be available during the downtime. In preparation for the downtime, the batch scheduler will not start jobs that cannot be completed before 7 a.m., May 7. Jobs that are not started on clusters will be held until after the downtime and then started once the system is returned to production status.

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.

Submission deadline for OSC Research Symposium is March 9
