# DOE Grand Challenge Applications Group in Quantum Chromodynamics

###
We are using the massively parallel computers at Oak Ridge and Los Alamos
national laboratories for numerical simulations of quantum chromodynamics,
the fundamental theory of the strong interactions of high energy physics.
We have developed a portable MIMD code which runs on the Paragon, CM5,
T3D, SP2, workstation clusters and other MIMD machines, and a SIMD code
optimized for the CM5, with key sections written in CDPEAC. These codes
are being used for computations of the properties of QCD at low and
intermediate energies. The main thrust of these computations is matrix
elements of strongly interacting particles, including the decay constant
of B mesons, pion scattering amplitudes, the kaon B parameter and
semi-leptonic form factors.
