Abstract

In this paper we discuss new Intel instruction extensions - Intel Advance Vector Extensions 2 (AVX2) and what these bring to high performance computing (HPC). To illustrate this new systems utilizing AVX2 are evaluated to demonstrate how to effectively exploit AVX2 for HPC types of the code and expose the situation when AVX2 might not be the most effective way to increase performance.
