Numerical simulations of interacting quarks and glu ons may be the best way to calculate the structure of protons and neutrons, as well as the nature of the very early universe or the interiors of neutron stars. Such simulations are limited by the availability of computer power. We are carrying out a program of simulations on multiple instruction, multiple data (MIMD) parallel computers. We describe here the goals of this project, discuss the way in which the computations are adapted to parallel computers and the performance they achieve, and present a few preliminary results.
