Introducing the Intel Xeon Phi Coprocesser

The Intel Xeon Phi coprocessor helps to enable dramatic performance gains for the most demanding applications. It takes advantage of familiar and standard programming models to preserve investments while extending hardware support to higher degrees of parallelism with power savings.

Programming the Xeon Phi

Programming the Xeon Phi Intel's tools provide standards-driven parallel programming models that can scale across cores and the techniques used benefit both processors and coprocessors. Programs that utilise multicore processors and many-core coprocessors have a wide variety of options to meet varying needs. These options fully utilise existing widely adopted solutions, such as C, C++, Fortran, OpenMP, MPI and Intel Threading Building Blocks (Intel TBB), and are rapidly driving the development of additional emerging standards such as OpenCL as well as new open entrants such as Intel Cilk Plus.

The graph to the right shows the performance advantage when using a Xeon Phi.
