We will have rolling reboots of Owens and Pitzer clusters including login and compute nodes, starting from 9AM Monday, July 11 2022.
Updates on Feb 25 2022:
This issue is fixed.
Users may see an issue of missing shared library with some mvapich2 modules on Pitzer and Owens. The error is like
<path_to_executable>: error while loading shared libraries: libim_client.so.0: cannot open shared object file: No such file or directory
We are in the process of rebuilding mvapich2 versions that are affected.
OSC will shut down significant portions of the Owens and Pitzer clusters for several hours this afternoon (Thursday, Feb. 10).
When requesting an interactive session in ondemand and requesting gpu resources, users may see an error similar similar to "sbatch: error: Invalid generic resource (gres) specification"
OSC staff are currently looking into this.
This issue has been resolved.
CP2K 6.1 would fail with the following error when running on Pitzer Cascade Lakes (48-core) node:

Thid could be a bug in libxsmm 1.9.0 which is released on Mar 15, 2018 (Cascade Lake is launched in 2019). The bug has been fixed in
You might encounter an error while pulling a large Docker image:

mpirun from OpenMPI can not be used in an interactive session (launched by
sinteractive) after upgrading Pitzer and Owens to Slurm 20.11.4. Please use
srun only while you use OpenMPI in an interactive session.
We will have rolling reboot of Pitzer cluster. User will expect a ~10 minute outage of login nodes at about 9AM Feb 05, 2021.
We have found some types of CP2K jobs would fail or have poor performance using cp2k.popt and cp2k.psmp from MVAPICH2 build (gnu/4.8.5 mvapich2/2.3). This version will be removed on December 15th, 2020. Please switch to Intel MPI build (gnu/7.3.0 intelmpi/2018.3).
A partial-node MPI job may fail to start using
intelmpi/2019.7 with error messages like
