[Hpc-notice] Thursday, August 19 HPC software update status

[Casey Mc Laughlin]

Hi HPC & Spear users,

We are continuing to make progress with the RCC software update.

The Login nodes have been upgraded to CentOS 8 and the new software stack. A few users have reported issues with software that they run, and we are working to correct those issues. We encourage you to try your jobs and report any issues to our support system: support at rcc.fsu.edu<mailto:support at rcc.fsu.edu>.

We also upgraded half of the owner compute nodes, and we plan on completing the other half tomorrow. All owner queues/partitions remain available during this upgrade.

We mentioned in an earlier announcement that we were making some changes to the Linux Environment Modules. If you have any module load ... directives in your submit scripts, you will probably be affected by these changes. We've published detailed documentation about these changes on our website<https://rcc.fsu.edu/docs/linux-modules>.

The basic takeaway is that modules are now hierarchical, which means that module load intel-openmpi now becomes module load intel openmpi (note the space instead of the dash). The old module syntax will work for a time, but we encourage everyone to update their scripts to the new format.

Finally, Python3 is now the default version. We are working on an environment module to load Python2. If you need that sooner than later, please let us know (support at rcc.fsu.edu<mailto:support at rcc.fsu.edu>).

Thanks for being patient while we work on this upgrade, and let us know if you encounter any unexpected issues. We will post another status update tomorrow.

Best regards,
The RCC Team
