New Default “Rerun” Behavior for PBS Jobs on NCAR’s HPC Resources

June 12, 2024

In response to a PBS issue observed in the past month, CISL staff have changed the default “rerun” behavior of submitted batch jobs on both Derecho and Casper. Previously, batch jobs were considered rerunnable by default, meaning that in case of startup issues, the scheduler would automatically attempt to rerun the job. After the PBS upgrade this past May, this feature began interacting negati...

How to Reduce Charges for Single-processor Derecho Batch Jobs

June 11, 2024

The jobs of concern here are Derecho batch jobs that are run with directive prefix #PBS -l select=1:ncpus=1 in the main queue. In many cases it may be better to run them in the develop queue. It will be helpful if you use the qhist command on some of your finished jobs to see if they are amenable to running in the develop queue. For example, command qhist -j 4701972 -d 5 -l will show you the...
