Stampede made its way into the No. 7 spot in November 2012, rose to No. 6 in June 2013 and then resumed its former place on the most recent list. Funding for the system came from an award from the National Science Foundation (NSF), and Stampede is housed at the Texas Advanced Computing Center (TACC) at the University of Texas in Austin. This Dell PowerEdge system runs Intel Xeon E5 8-core 2.7GHz processors in conjunction with Intel Xeon Phi coprocessors. Its roughly 462,000 cores allow it to achieve nearly 5.2 petaflops in performance.

Since January 2013, Stampede has been open for use by scientists and other researchers in all fields as part of the NSF's Extreme Science and Engineering Discovery Environment (XSEDE) program, a virtual system for openly sharing the computing power of 16 supercomputers and related resources. Ninety percent of the system is dedicated to XSEDE and the rest is at the discretion of the TACC's director. Qualified researchers at any U.S. institution can submit proposals via the XSEDE Web site.
