Improve Server Application Performance with Intel® Advanced Vector Extensions 2

The Intel® Xeon® processor E7 v3 family now includes an instruction set called Intel® Advanced Vector Extensions 2 (Intel® AVX2), which can potentially improve application performance related to high performance computing, databases, and video processing. To validate this statement, I performed a simple experiment using the Intel® Optimized LINPACK benchmark. The results, as shown in Table 1, show a greater than 2x performance increase using Intel AVX2 vs.
