Stampede2

Phase 1 System Now Available

Stampede2 is the flagship supercomputer at The University of Texas at Austin's Texas Advanced Computing Center (TACC). A strategic national resource, Stampede2 will provide high-performance computing capabilities to thousands of researchers across the U.S. It will enter full production in fall 2017 as an 18 petaflop system that builds on the successes of the original Stampede cluster it replaces. Phase 1 of the Stampede2 rollout, now complete, features 4,200 Knights Landing (KNL) nodes, the second generation of processors based on Intel's Many Integrated Core (MIC) architecture. Later this summer Phase 2 will add 1,736 Intel Xeon Skylake nodes.

Stampede2 will be deployed by TACC in conjunction with vendor partners Dell Inc., Intel Corporation, and Seagate Technology, and operated by a team of cyberinfrastructure experts at TACC, UT Austin, Clemson University, Cornell University, the University of Colorado at Boulder, Indiana University, and Ohio State University.

Stampede2 is generously funded by the National Science Foundation (NSF) through award ACI-1540931.
