Users may experience unable to unload Intel software stack via module rm intel after switching between intel and ohter compilers. This is a known issue with current versions of Lmod on Pitzer and Ruby. The issue will be fixed by upgrading Lmod during system-wide downtime May 19th.

Users may encounter under-performing MPI jobs or failures of compiling MPI applications if you are using Conda from system. We found pre-installed mpich2 package in some Conda environments overrides default MPI path. The affected Conda packages are python/2.7-conda5.2 and python/3.6-conda5.2. If users experience these issues, please re-load MPI module, e.g. module load mvapich2/2.3.2 after setting up your Conda environment.

We will have rolling reboots of all three clusters starting 9:30 AM June 05, 2019.

There have been problems with PBS torque commands including qsub  and  qstat  from the Ruby login nodes since this morning.
