High performance C++ computing examples developed for resources available from the Texas Advanced Computing Center at the University of Texas

These examples were developed for the Stampede system.

The TACC Stampede system is a 10 PFLOPS (PF) Dell Linux Cluster based on 6,400+ Dell PowerEdge server nodes, each outfitted with 2 Intel Xeon E5 (Sandy Bridge) processors and an Intel Xeon Phi Coprocessor (MIC Architecture).

Simple example of running a shared memory application using OpenMP.

Simple example of running a distributed, single-program multiple-data (SPMD) application using MPI.

Example of combining the above two applications. The application program implements an extremely naive prime counting function and allows the user to run it either as a single threaded, multi-threaded (OpenMP), or hybrid application (OpenMP+MPI).
