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.

Quick Facts

-Terra is an x86 general compute cluster, like Ada

-Terra is smaller than Ada and has some different hardware (link hardware page)

-Software on Terra will be similar to Ada, but may not match exactly

--Link software page for general listing

--Use module spider or module avail for the most up-to-date list

-The environment on Terra is different than Ada. Your Ada scripts may need to be adjusted.

-Terra uses **SLURM** instead of LSF. Your Ada/LSF batch jobs will need to be converted. Resource requests may need to be adjusted.


The hardware on Terra differs than that on Ada. There are fewer nodes and cores overall, but more cores per node.

There are also more GPU nodes are available on Terra than Ada, but each GPU node only has a single GPU.

The software available on Terra is similar to that on Ada.


The Terra environment is much different than Ada. While much of the software is still implemented with modules, the filepaths for HOME, SCRATCH, ... have been changed. User-created scripts may need to be adjusted when transitioning between Ada and Terra.

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 JOBFILE TRANSLATION PAGE contains information on converting between LSF, PBS, and Slurm.

Example Jobs

A handful of job examples have been translated between Ada and Terra. These general examples can be seen 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.
