Early performance evaluation of AVX for HPC
Paweł Gepner, Victor Gamayunov, David L. Fraser · Procedia Computer Science · 2011
In this paper we take a look at what the new Intel instruction extensions - Intel Advance Vector Extensions (AVX) brings to high performance computing. We compare two configurations of Intel CPU based systems (one enabled with AVX and a second without AVX enabled) and present a performance evolution of these two platforms. We compare the same generation of CPU utilizing a single socket platform across a number of HPC benchmarks and macrocodes focused on different performance criteria, compare the results and discuss the implications for HPC.
