Stampede

Cutting-edge HPC, Visualization, Data Analysis, and Data-Intensive Computing


After a remarkably successful run, the Stampede supercomputer at TACC at UT Austin completed its full four-year period on January 7, 2017. During its four years of operations, Stampede ran more than eight million successful jobs, delivered over three billion core hours of computation, and ran jobs for more than 11,000 users on over 3,000 projects in the open science community. In January, TACC will begin the deployment of the new Stampede-2 system, which will be deployed in phases during 2017.

We are very pleased to announce that TACC will continue to offer access to a portion of Stampede while Stampede2 is being deployed in an ‘extended operations' phase. We appreciate your patience during this transition, and look forward to working with all of you to continue to deliver groundbreaking science on the Stampede systems.


Stampede is one of the most powerful and significant current supercomputers in the U.S. for open science research. Able to perform nearly 10 quadrillion operations per second, Stampede offers infinite opportunities for computational science and technology— ranging from highly parallel algorithms, high-throughput computing, scalable visualization, and next generation programming languages. This Dell PowerEdge cluster equipped with Intel Xeon Phi coprocessors pushes the envelope of computational capabilities, enabling breakthroughs never before imagined. Stampede is funded by the National Science Foundation (NSF) through award ACI-1134872. XSEDE is funded by the National Science Foundation (NSF) through award ACI-1053575.

Thank you to everyone who has helped make Stampede possible: National Science Foundation, The University of Texas at Austin, Dell Inc., Intel Corporation, Mellanox Technologies, Clemson University, Cornell University, The Ohio State University, The University of Texas at El Paso, Indiana University, The University of Colorado at Boulder, and the Institute for Computational Engineering and Sciences (also at The University of Texas at Austin).

2016 Stampede Upgrade

Stampede has been upgraded by adding additional compute nodes built around the second generation of the Intel Xeon Phi many-core, x86 architecture, known as Knights Landing. The new Xeon Phi's function as the primary processors in the new system.

The upgrade ranked #116 on the June 2016 Top 500, and was the only #KNL system on the list.
