Batch Nodes/Queues

In 2021 LCLS switch to the SLURM batch system.

...

Note 1: Jobs for the current experiment can be submitted to fast feedback (FFB) queues, which allocate resources for the most recent experiments. The FFB queues in the tables below are for LCLS-II experiments (TMO, RIX and UED). The FEH experiments (LCLS-I, including XPP) can submit FFB jobs to the new Fast Feedback System.

Warning

As of February 2023, the offline compute resources have been consolidated into the psanaq. The priority queues have been removed.
