Fill out the account request form on the TACC Account Management Portal and it will be reviewed by our User Services team.

Faculty, professional research staff, and postdoctoral researchers may request Principle Investigator (PI) eligibility for their account. PIs are responsible for requesting system allocations and managing their team.

Graduate and undergraduate students can create an account, but must be added to allocations by PIs to use the systems.

Request an Allocation

To access a system, you must request through an allocation opportunity.

Browse the System List, Allocations, and Software List to help determine what system and allocation fits your research.

If you are a PI, log into your account and request an allocation on the system that fits your research needs.

Frontera Maintenance Tuesday 11 November 2025

Frontera will not be available from 8 a.m.  on Tuesday, November 11 until  8 a.m. on Wednesday, November 12,  2025. System maintenance will be performed during this time.

Ranch Status Saturday November 1 2025

The building housing the old Ranch system experienced a partial power outage that we currently investigating. The new Ranch system in our ROC data center has not been affected, but transfers from the old system (OldRanchData directory) will hang until power to the system is restored, and the transfers should continue automatically once power is restored. The new Ranch login nodes may also be unresponsive at this time. We will post an update when the power is restored.
