Proposal Title: Collaborative Research: Multigrid QCD at the Petascale

Institution: Trustees of Boston University

Abstract Date: 10/10/07







Numerical solutions to Quantum Chromodynamcs on a lattice are critical to high

precision experimental tests of the standard model and an ab-initio understanding of

nuclear matter. The core of these calculations involves inverting a Dirac matrix which

becomes increasingly ill conditioned as the lattice is refined. Consequently while

Terascale computing hardware has exposed this new physics, it is incapable of fully

accommodating it. On the other hand, if lattice QCD algorithms are reformulated to

exploit and reveal the physics at this finer microsale, Petascale hardware does have the

potential for opening up a new era of physics discovery. This award brings together a

close collaboration of leading experts in applied mathematics and theoretical physics to

meet this challenge by the application of new multi-level algorithms for QCD

simulations. The central mission of the proposed Multigrid Quantum

Chromodynamics at the Petascale project (MGQCD) is: to develop new and significantly

more robust multigrid methods for enabling more complex and higher fidelity physics for

lattice QCD calculations; to support their migration into Petascale simulations; and to

engage the broader scientific community through collaborative research and

educational activities that highlight the multigrid methodology.
