The Stampede supercomputer at the Texas Advanced Computing Center went into production in January 2013 and was the first system to deploy at scale the Intel Xeon Phi CoProcessor. Stampede provides nearly 10 petaflops (PF) of peak performance and is the flagship system of the National Science Foundation’s XSEDE program. Stampede provides more than 100,000 cores and 2PF of Intel Xeon E5 “Sandy Bridge” processors and an additional 7+ PF of Intel Xeon Phi coprocessors.

In this tutorial, we will introduce the Stampede architecture, describe the user environment, and discuss optimization techniques for both conventional processors as well as the Xeon Phi coprocessors.

Topics will include:

• Stampede architecture overview.
• Stampede user environment, including the batch system, compiler environment, application modules, etc.
• MPI and OpenMP parallel programming
• Hands-on exercises on Stampede.
• Basic optimization and vector tuning on Stampede for Sandy Bridge and Xeon Phi Coprocessors (MICs)
• Hybrid computing
• Intel Xeon Phi Coprocessor (MIC) overview
• Programming models for Sandy Bridge – MIC computing: native, symmetric and offload.
