New User Information
The information on this page is designed to enable you to quickly:
- Learn about TACC resources available to eligible user communities;
- Select the TACC resource most appropriate to solve your problem;
- Request a project and allocation on one or more TACC resources;
- Gain an awareness of TACC training activities; and
- Know where to go for more detailed information on the resources and how to most efficiently use them.
TACC provides the computational user community access to petascale computing systems, remote and collaborative visualization resources, high-performance, local disk file systems, a data applications facility and a petascale data archive.
The Dell PowerEdge C8220 Cluster with Intel Xeon Phi coprocessors, Stampede, is now operational and available to the national open science community (as of January 7, 2013). Stampede is intended primarily for parallel applications scalable to tens of thousands of cores. Normal batch queues will enable users to run simulations up to 24 hours. Jobs requiring run times and more cores than allowed by the normal queues may be run in a special queue after approval by TACC staff. Serial and development queues will also be configured. In addition, users will be able to run jobs using thousands of the Intel Xeon Phi coprocessors via the same queues to support massively parallel workflows. Configuration details and information on how to efficiently use the system can be found in the Stampede User Guide.
The Dell Linux Xeon cluster, Lonestar, should be the computational resource of choice for users with parallel, MPI codes that take advantage of a large, distributed-memory architecture. Development and serial queues enable users to port and develop models that can scale from tens, to hundreds, or even thousands of processors. See the Lonestar User Guide for system configuration and instructions on how to efficiently use the system.
The TACC DELL/NVIDIA Visualization and Data Analysis cluster, Longhorn, is a hybrid CPU/GPU system designed for remote, interactive visualization and data analysis. In addition, Longhorn supports production, compute-intensive calculations on both the CPUs and GPUs via off-hour queues. The large, per-node memory is intended to support serial and parallel visualization and analysis applications that take advantage of large memories, multiple computing cores, and multiple graphics processors.
The TACC Visualization Laboratories contain a number of high-resolution resources dedicated to providing interactive and collaborative visualization environments, including Stallion, currently the world's highest-resolution tiled display.
Researchers at UT Austin, UT System and Texas higher education institutions may apply for access to TACC resources and services by requesting a TACC project and allocation via the TACC User Portal. Members of the research community at other institutions must apply for a National Science Foundation XSEDE project to access TACC. Additional information on the types of XSEDE allocations and how to apply can be found at the XSEDE web site. UT Austin, UT System and Texas higher education researchers may also apply for XSEDE allocations but must do so through the XSEDE web site. Detailed information on the eligibility requirements for using TACC resources is available via the TACC web site.
Before requesting a project and allocation, UT Austin and UT System users must request a new TACC account.

New TACC users are encouraged to attend TACC short courses. A variety of courses are offered, covering topics in high-performance computing, scientific visualization, and distributed and collaborative computing. Students are provided with all presentation materials for future reference. TACC staff members also make available and maintain a set of user guides to assist users continue to improve their knowledge of the resources. During normal business hours, personal assistance from the TACC consulting staff can be requested via the TACC Consulting System available through the TACC User Portal. XSEDE users must request assistance by sending email to firstname.lastname@example.org.
