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.
Most access to Terra is done via a secure shell session.
Users on Mac and Linux/Unix should use whatever SSH-capable terminal is available on their system.
The command to connect to Terra is as follows. Be sure to replace [NetID] with your TAMU NetID.
Your login password is the same that used on Howdy. You will not see your password as your type it into the login prompt.
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.
#!/bin/bash #SBATCH --export=NONE #SBATCH --get-user-env=L #SBATCH -t 01:00:00 #SBATCH -J ExampleJob #SBATCH -N 1 #SBATCH -n 1 #SBATCH --mem=5G #SBATCH -o ExJobOut.%j module load ExampleModule ./myprogram
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.

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.
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.
