Alumni Project

National Infrastructure for Lattice Gauge Computing

The project will focus on simulations of quantum chromodynamics (QCD), the sector of the Standard Model of elementary particle physics that describes the strong forces between particles. The entire US community of theorists, both nuclear physicists and high-energy physicists, who work on Lattice Gauge theory, have joined together in this proposal. There is no doubt that in order to achieve the sort of scientific breakthroughs they are aiming at, highly cost-effective terascale computing resources will be needed. This project aims to fully understand the performance and costs for both a special-purpose Lattice Gauge Theory super-computer and for clusters of commodity computers, with special-purpose interconnects. It will also lay the foundations necessary to build community-wide codes that can take maximum advantage of future computing hardware.

These calculations, when carried out on terascale machines, will provide important theoretical insights and support for the large experimental efforts in high energy and nuclear physics.
