About High-Performance Computing

The Texas Christian University Advance Computing Center (TCUACC) provides an environment for high-performance computing ideal for small jobs that require a bit more power than your department may have readily available.  The TCU primary cluster can be used for batch or MPI workloads.

Requesting Additional Software

If there is a software package that you need for a research project please contact us with a specific package and version.  If it can be added nondestructively then once it is approved it will be rolled out on the next maintenance cycle.  If it has conflicts with existing packages then a decision will be made by the HPC committee.

Upgrades and Software Change Schedule

Cluster access is typically restricted during the final two weeks of July in order for system-wide maintenance to be performed including OS version updates and new networking infrastructure.  Most other routing maintenance and software changes are done throughout the year as needed.  Hardware is upgraded in a three-on-three off-schedule.

How do I put in a request for the following type of issues?
