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
Apptainer container builds fail on compute nodes due to /tmp namespace behavior
Building Apptainer containers on compute nodes may fail during apt update or other package operations. The failure is caused by Apptainer’s build environment not being fully isolated from the host when private /tmp namespaces are in use.
Schrodinger 2023.2 does not launch
Schrodinger 2023.2 does not launch through OnDemand or OnDemand desktop, failing with "fatal error"
Schrodinger can be launched on vis nodes, through X11Forwarding, and through batch jobs. If trying to run Schrodinger 2023.2, please use a vis node, use X11Forwarding, or do not use the GUI and run through a batch job
This issue is due to system incompatibilities on RHEL 9.4, which is not supported by Schrodinger 2023.2
AlphaFold 3 GPU Out-of-Memory Error During Inference
When you run AlphaFold 3, you may encounter a GPU out-of-memory (OOM) failures during model execution. The job terminated with errors similar to:
Code Server ondemand.osc.edu cannot open this folder because it contains system files
Trying to download a directory through code server results in the error "ondemand.osc.edu cannot open this folder because it contains system files"
To work around this, tar the directory first and download the .tar file, and untar it on your local machine
MVAPICH 3.0 hang due to PMI mismatch with Slurm
Applications such as Quantum ESPRESSO, LAMMPS, and NWChem experienced hangs with MVAPICH 3.0 due to a PMI mismatch. MVAPICH 3.0 was built with PMI-1, while newer Slurm versions on RHEL 9 use PMI-2. Although the development team states that using the PMI-1 interface with Slurm’s PMI-2 implementation should work, there may be a bug in MVAPICH 3.0.
Testing Issue for Quantum Espresso 7.4.1 on Ascend

Update on November 24, 2025: The issue is resolved with MVAPICH 4 variants.
