AlphaFold 3 Warning: NVIDIA Driver Version Mismatch
While running AlphaFold 3, you may encounter the following warning message:
Software
MPI fails with UCX 1.18
After the downtime on August 19, 2025, users may encounter UCX errors such as:
UCX ERROR no active messages transport to <no debug data>: self/memory - Destination is unreachable
when running a multi-node job with intel-oneapi-mpi/2021.10.0, mvapich/3.0 or openmpi/5.0.2.
MATLAB (server) missing functionality
You may encounter missing functionality on MATLAB (server) such as SIMULINK not being available. This occurs when using MATLAB version r2024a. Please use MATLAB r2024b
If there are still issues with MATLAB r2024b, please open a ticket
cp2k/2023.2 can produce huge output containing MKL messages
On all clusters the cp2k executables from module cp2k/2023.2 can produce huge output files due to many many repeating errors from MKL, e.g.:
Poor performance with hybrid MPI+OpenMPI jobs and more than 4 MPI Tasks on multiple nodes
RELION versions prior to 5 may exhibit suboptimal performance in hybrid MPI+OpenMP jobs when the number of MPI tasks exceeds four across multiple nodes.
Workaround
If possible, limit the number of MPI tasks to four or fewer to achieve optimal performance. Alternatively, consider upgrading to RELION version 5 or later, as these newer releases may include optimizations and improvements that resolve this performance issue.
Docker container runtime error on desktop due to DBUS session
When running a container using the podman or docker command on a desktop system, you may encounter an error like the following:
Error: OCI runtime error: crun: sd-bus call: Process org.freedesktop.systemd1 exited with status 1: Input/output error
A similar issue has been discussed in Podman GitHub Issue #13429, and it has been concluded that this is not a Podman bug.
Podman storage error due to outdated configuration file
If you experience a storage error such as:
write /var/tmp/storage388772891/1: no space left on device.
you may have an outdated ~/.config/containers/storage.conf file, possibly generated by an older Podman installation on a RHEL 7 system. Removing this file should resolve the issue.
Apptainer sandbox fails on GPFS due to stale NFS file handles
Users may encounter errors when attempting to run a sandbox on GPFS-mounted directories such as /fs/scratch or /fs/ess. The error output may look like the following:
CP package hang with MVAPICH3 in Quantum-Espresso
While using MVAPICH3 builds of Quantum ESPRESSO (QE), users may encounter hangs when running the CP package, which can lead to job timeouts. We recommend switching to the OpenMPI build of any QE version.
Please switch to Intel-OpenMPI version. You can access it via
module load intel/2021.10.0 openmpi/5.0.2 module load quantum-espresso/7.3.1
Note that MVAPICH3 variants will be deprecated on August 19, 2025
Update on November 24, 2025: MVAPICH 4 variants are now available for version 7.4.1.
Some MKL environment variables have incorrect paths
MKL module files define some helper environment variables with incorrect paths. This can yield link time errors. All three clusters are affected. We are working to correct the module files. A workaround for users is to redefine the environment variable with the correct path; this requires some computational maturity. We recommend users contact oschelp@osc.edu for assistance. An example error from Cardinal with module intel-oneapi-mkl/2023.2.0 that defined environment variable MKL_LIBS_INT64 follows:
