Terra Usage Policies

Access to Terra is granted with the condition that you will understand and adhere to all TAMU HPRC and Terra-specific policies.

General policies can be found on the HPRC Policies page.

Terra-specific policies, which are similar to Ada, can be found on the Terra Policies page.

Accessing Terra

Most access to Terra is done via a secure shell session.

Users on Windows computers use either PuTTY or MobaXterm. If MobaXterm works on your computer, it is usually easier to use.

Users on Mac and Linux/Unix should use whatever SSH-capable terminal is available on their system.

Writing a Job

In order to properly run a program on Terra, you will need to submit a job.

The simple example below request 1 core on 1 node with 5GB of RAM for 1 hour. "ExampleModule" should be replaced or omitted based on your software needs.

#SBATCH --export=NONE
#SBATCH --get-user-env=L
#SBATCH -t 01:00:00
#SBATCH -J ExampleJob
#SBATCH -n 1
#SBATCH --mem=5G
#SBATCH -o ExJobOut.%j
module load ExampleModule

This job file should be written on a Linux/Unix environment.

If written on an older Mac or DOS workstation, you will need to use "dos2unix" to remove certain characters that interfere with parsing the script.

dos2unix myExJobFile.slurm

More information on job options can be found in the Building Job Files section of the Terra Batch page.

More information on dos2unix can be found on the dos2unix section of the HPRC Available Software page.

Batch System

Terra uses Slurm instead of LSF as a batch system facilitator. All job files for Terra will need to be written in Slurm in order to run properly.

The Terra Batch System page contains information on writing, submitting, and monitoring Slurm jobs on Terra.

The HPRC Batch Translation page contains information on converting between LSF, PBS, and Slurm.

Example Jobs

A handful of Slurm job examples have been written as templates for use on Terra. These examples can be found in the | Job File Examples section of the Terra Batch page.

Some LSF-Slurm translation examples have also been made available on the ADA-TERRA JOBS TRANSLATION PAGE. Our staff has also written some example jobs for specific software. These software-specific examples can be seen on the INDIVIDUAL SOFTWARE PAGES where available.
