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.

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.

User Updates

GPU Small Queue Now Available

Lonestar6 has a new queue, "gpu-a100-small" designed for users who do not need a node's entire 3 GPUs in the "gpu-a100" queue. The jobs in this queue consume 1/3 of the full resources of a full node. If your job uses only a single GPU and less than 70GB of memory, you should try running in the "gpu-a100-small" queue. The charge rate for the "gpu-a100-small" queue is 1.5 SUs per node hour. Please submit any questions you may have through the TACC Consulting System or feedback form. https://tacc.utexas.edu/portal/ticketshttps://tacc.utexas.edu/about/help/
