    11= Programming for the Xeon Phi Coprocessor on Cypress =
     2The Xeon Phi coprocessor is an accelerator used to provide many cores to parallel applications. While it has fewer threads available than a typical GPU accelerator, the processors are much "smarter" and the programming paradigm is similar to what you experience coding for CPUs.

    34== Xeon Phi Coprocessor Hardware ==
     
    56Each compute node of Cypress is equipped with two (2) Xeon Phi 7120P coprocessors

     10The 7120p is equipped with
     11* 61 Physical cores running at 1.238 GHz
     12* Four (4) Hardware threads on each core
     13* 16GB GDDR5 memory
     14* Uniquely wide SIMD capabilities via 512-bit wide vectors (16 doubles!)
     15
     16All this adds up to about 2GFLOPS of potential computing power.
