Steps to getting started using the Physics Farm system at Jefferson Lab:

Slurm for Computing Coordinators

The management of slurm accounts can be delegated to computing coordinators. This is useful for changing which users can run jobs against slurm accounts. It can also be used withn an account to impose or remove user contraints. These commands should be run from an ifarm machine. 

 

Examples using username "alice" and account "hallx"

 

Experimental Physics User's Guide

The scientific computing environment for experimental physics is comprised of a data analysis facility and its accompanying mass storage system. Details on the hardware are in the Scientific Computing Resources book.

The data analysis environment includes the batch "farm" (a compute cluster) plus its associated interactive nodes and disk storage systems.  Multiple files systems are accessible from both the interactive and batch nodes, and some of these are also accessible from desktops onsite.

Volatile Area Data Management Policy

The /volatile area is managed by an automated process that cleans up periodically in multiple steps as listed below. In the rules mentioned below the target threshold is defined as the "aggregate used space by all projects".

Cache manager policy

When a project is over their High Quota limit the following data backup and deletion policies will be enforced.

/cache Backup policy:
