Sycamore Cluster Partitions, QoS, and User Limits

The jobs limits are determined by the partition you submit to and the QoS (Quality of Service) associated with that partition. The default time is the time alloted for the job if it is not specified by the user. The mincpu is the least number of cores that can be requested in that partition. The maxcpu is the maximum number of cores a user can allocate summed across all of their jobs.

batch partition and batch QoS

• max run time 5 days
• default time 2 hours
• mincpu 48
• maxcpu 5000
• this is the default partition

lowpri partition and batch QoS

• max run time 5 days
• default time 2 hours
• mincpu 48
• maxcpu 5000

small partition and small QoS

• max run time 5 days
• default time 2 hours
• mincpu 2
• maxcpu 192

inter partition and inter QoS

• max run time 8 hours
• default time 2 hours
• mincpu 1
• maxcpu 96

Rationale for each partition:

**batch and lowpri These are similar partitions with the exception that the lopri (for lower priority work) actually has a higher Slurm priority and may pend for a shorter amount of time. The caveat is that the job can be suspended at the discretion of the Slurm administrator is a higher priority job needs to run.

**small For jobs running on between 2 and 192 cores.

**inter Interactive jobs.
