Terra:Batch Job Files
While not the only method of submitted a job, job files fulfill the needs of most users.
The general idea behind job files follows:
- Make resource requests
- Add your commands and/or scripting
- Submit the job to the batch system
Several of the most important options are described below. These options are typically all that is needed to run a job on Terra.

Several examples of Slurm job files for Terra are listed below. For translating Ada/LSF job files, the Batch Job Translation Guide provides some reference.
