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.

Specification Option Example Example-Purpose
Node Count -N [min[-max]] -N 4 Spread all cores across 4 nodes
Operating System: Linux (CentOS 7)
Total Compute Cores/Nodes: 8,512 cores
304 nodes
Compute Nodes: 256 compute nodes, each with 64GB RAM
48 GPU nodes, each with a single Tesla K80 GPU and 128GB of RAM
Interconnect: Intel OmniPath100 Series switches.
Peak Performance: ~X TFLOPs (TBD)
Global Disk: 1.5PB (raw) via IBM's GSS26 appliance for general use
1.5PB (raw) via IBM's GSS256 purchased by a dedicated for GeoPhysics
File System: General Parallel File System (GPFS)
Batch Facility: Slurm by SchedMD
Location: Teague Data Center
Production Date: Fall 2016 (tentative)

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.

Documentation for advanced options can be found under Advanced Documentation.
