= Programming for the Xeon Phi Coprocessor on Cypress = The 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. == Xeon Phi Coprocessor Hardware == Each compute node of Cypress is equipped with two (2) Xeon Phi 7120P coprocessors [[Image(xeonPhi.jpg, center)]] The 7120p is equipped with * 61 Physical cores running at 1.238 GHz * Four (4) Hardware threads on each core * 16GB GDDR5 memory * Uniquely wide SIMD capabilities via 512-bit wide vectors (16 doubles!) All this adds up to about 2GFLOPS of potential computing power. == Xeon Phi Usage Models ==
