Casper users will notice some service changes as the cluster is migrated from Slurm to the PBS job scheduler over the next couple of weeks. The first change involves the vncmgr script, which allows users to start VNC sessions on Casper nodes. This script uses Slurm now, but will be migrated to PBS on Monday, March 29. Changes will be minimal, but custom scheduler options must be specified in PB...
The NCAR/UCAR virtual Python Tutorial Seminar Series continues on Wednesday with an introduction to the Python package Matplotlib at 1 p.m. MDT. See the Xdev team’s blog for details. Participants who did not attend the earlier Jupyter Notebooks tutorial are advised to watch this recording before attending the Matplotlib session.
The Casper cluster now has 64 new high-throughput computing (HTC) nodes, which are for batch jobs that require the use of one full node or less. As the first step in migrating the Casper system’s scheduler from Slurm to the PBS Pro workload manager, the HTC nodes are accessible only through PBS Pro. This new documentation provides details for preparing PBS scripts and submitting jobs on Casper:...
