HPC/Submitting and Managing Jobs/Queues and Policies

Default queue

The main queue on Carbon is batch and need not be specified.

All job routing decisions are handled by the scheduler. In particular, short jobs are accommodated by a daily reserved node and by backfill scheduling, i.e. "waving forward" while a big job waits for full resources to become available.

Using the debug queue

For testing job processing and your job environment, use qsub -q debug on the command line, or the follwing in a job script:

#PBS -q debug

The debug queue accepts jobs under the following conditions

nodes ≤ 2
ppn ≤ 4
walltime ≤ 1:00:00
