Farm User's Guide v2

The Jefferson Lab scientific computing environment for experimental physics is comprised of:

• Data analysis facility: 
  • interactive and batch nodes called "farm".
• Mass storage system:
  • multiple files systems accessible from both interactive and batch nodes, and some of these are also accessible from desktops onsite.
• Auger:
  • The compute cluster is managed by JLab's in-house Auger software, which uses the SLURM batch system and scheduler as a job execution engine. Auger interfaces with the online and offline storage subsystems to move files between disk and a robotic tape library.
• SWIF:
  • SWIF allows users to carry out large data analyses efficiently by grouping many jobs into a workflow and by scheduling jobs according to input file locations on one or more tapes. In addition, SWIF provides phased job release to Auger, and ease of job modification, re-submission, recall and cancellation, and delivers detailed job metrics during and after a workflow.
