Create an Account

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.

Create Account

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.

TAP Connection Issues May 6 2026

We are aware of an issue for users of the TAP Portal (https://tap.tacc.utexas.edu/jobs/) regarding connection errors and the unavailability of ports. Our administrators are working to resolve the issue. We will update this post once the issue is resolved. Thank you, The TACC Team

TACC Resource Availibility

Due to security updates, all TACC resources will be affected and will be temporarily unavailable as the patches are applied. Jobs currently running will finish, and jobs currently in the queues will be held until the updates have completed. Login nodes will be intermittently unavailable during this process and this will affect queue wait times. We appreciate your patience as we perform this necessary maintenance. Please refer to this announcement for updates.

Horizon System Now Accepting Early Operation

TACC is pleased to announce that we are now accepting LRAC submissions for the Horizon supercomputer. Horizon’s Leadership Class Computing capacity is funded by the National Science Foundation and supports the “discovery at the frontiers of science and engineering…through large scale simulation, data analysis, and artificial intelligence applications.”Horizon provides an order of magnitude performance increase over the previous Frontera system and will enable researchers to advance the state of science in every field.Currently, we are only accepting large scale LRAC requests, but smaller research allocations and startup requests will be available in the future.Please review the submission guide for detailed instructions on how to proceed:https://lccf.tacc.utexas.edu/allocations We look forward to working with you!Thank you, The TACC Team
