Chapter 26

Quantum chromodynamics

Abstract

Explores Lattice QCD (Quantum Chromodynamics), which models the nuclear strong force that binds matter together, on Knights Landing. Optimization and performance results are discussed.

Keywords

LQCD; Quantum chromodynamics; Prefetching; MCDRAM

What is new with Knights Landing in this chapter?

Knights Landing proves easier to get performance than on Knight Corner. MCDRAM boosts performance in both cache and flat memory modes, and software prefetching is no longer required.

Lattice quantum chromodynamics (LQCD) is an important application for calculations in Nuclear and High Energy particle physics, and LQCD codes are frequently among the first to be ported to new generations of supercomputers. In ...
