STAR-CCM+ OpenMPI Job Failed due to Out-of-Memory
After the scheduled downtime on May 12, 2026, STAR-CCM+ has been encountering out-of-memory errors when running OpenMPI jobs. A message similar to the following appears repeatedly in the output:
[c0317.ten.osc.edu:1736021] Read -1, expected 133860, errno = 1
We have not yet identified the root cause of the issue; however, we have discovered that this error does not occur in multi-node jobs.
MATLAB (legacy) r2024a fails to launch on OnDemand Desktop
As of the downtime on 05/12/26 MATLAB (legacy) has stopped working when users try to open .m files in the GUI application for version r2024a. At the time we suggested to please use the server based MATLAB option underneath "Interactive Apps" > "Servers" > "MATLAB". Or, use any version other than MATLAB (legacy) r2024a
This has since been resolved
autodock-gpu 1.5.2 does not work on Cardinal
autodock-gpu/1.5.2 does not work on Cardinal. We suggest using autodock-gpu/1.6 instead
Classroom Jupyter and RStudio Apps
If you have classroom projects at OSC that used the Jupyter or RStudio apps through class.osc.edu before June 30, 2025 and plan to reuse your classroom environment, the PI will need to complete the following one‑time update:
Wine32 Segmentation Fault
Users have reported that running Wine32 (32-bit Wine) results in a Segmentation fault (core dumped). The issue is linked to how cgroups (control groups) are handled or enabled on specific compute nodes or environments.
starccm does not use vis node GPU
Issue:
When trying to run starccm on a vis node in order to use GPU for visualization (not for GPU calculation), the typical way to do this would be to load the virtualgl module and use vglrun
module load virtualgl/3.1.1
module load starccm/19.06.009
vglrun starccm+
However, starccm does not pick up libraries from $LD_LIBRARY_PATH by default, so it does not pick up the necessary graphics libraries
vLLM versions prior to 0.14.1 are deprecated
vLLM versions prior to 0.14.1 are deprecated due to security issue CVE-2026-22778 which can allow remote code execution. Clients are advised to use versions 0.14.1+ with module load vllm/0.14.1

On any compute node, users may encounter the following error when installing packages with apt in Apptainer:
GPU/VIS nodes for various OOD apps are broken
After the most recent downtime we discovered that various OOD apps relying on the "virtualgl" module on Cardinal were broken. We have since updated and pinned the latest virtualgl version for each broken app
