Credential Caching
Description
Occasionally some users' credentials are getting cached on Beartooth that prevents them from logging in.
Solution
We have a script in place that clears the cache on the system that runs every hour on the hour. We can also run this manually if users run into trouble with logging into Beartooth when they have previously been able to login before and can’t wait for the hourly script.

8/11/21: Intel MPI 2018.x.y and Earlier Libraries and Related Applications Failing
Description
Since the last maintenance where Slurm has been updated we have noticed a backward incompatibility issue when using with the Intel MPI libraries. Any application that uses the intel-mpi 2018.x.y and earlier libraries will fail to run.
For example, if you have a local version of say VASP that has been built and uses module load intel-mpi.x.y
Solution
To resolve the issue, insert the following after the srun command within your command-line / submission script: srun --mpi=pmi2
You do not have to recompile your software nor application.
