Use which hardware PMU events to calculate FLOPS on Intel(R) Xeon Phi(TM) coprocessor?

FLOPS means total floating point operations per second, which is used in High Performance Computing. In general, Intel(R) VTune(TM) Amplifier XE
only provides metric named Cycles Per Instruction (average CPI), that is to measure performance for general programs.

IIR Gaussian Blur Filter Implementation using Intel® Advanced Vector Extensions

This white paper proposes an implementation for the Infinite Impulse Response (IIR) Gaussian blur filter using Intel® Advanced Vector Extensions (Intel® AVX) instructions. For a 2048x2048 image size, the AVX implementation is ~2X faster than the SSE code.
