Web version of Pinot Job Limits

There are 186 compute nodes, with 36 cores and 128 GiB of memory on each node.

Jobs are scheduled per node. Pinot has 2 scheduling pools (or partitions):

• pdebug—4 nodes, interactive use only.
• pbatch—182 nodes, batch use only.

Pools               Max nodes/job    Max runtime
------------------------------------------------
pdebug                    4            1 hour
pbatch                  138           12 hours
------------------------------------------------

Please be a good neighbor. During normal work hours, Monday-Friday from 8:00AM-6:00PM (Pacific time), we request users be considerate of other Pinot users and not utilize more than half of the pdebug nodes at a time. Please also do not stack the pdebug queue. The pdebug queue is scheduled using fairshare.

Hardware

Each node has 2 18-core Intel Xeon E5-2695 v4 (Broadwell) processors (2.1 GHz) and 128 GiB of memory. Pinot uses an Intel Omni-Path high speed interconnect.

Scheduling

Pinot jobs are scheduled through SLURM
