Objective

Create the software and hardware infrastructure needed for terascale simulations of Quantum Chromodynamics (QCD).

Scientific Goals

Non-perturbative Study of QCD

• Calculation of Weak Decays of Strongly Interacting Particles

  • Determination of least-well-known parameters of the Standard Model

  • Precision tests of the Standard Mode

• Investigation of Matter under Extreme Conditions

  • Mapping the phase diagram of strongly interacting matter

  • Determining the properties of the Quark-Gluon Plasma

• Understanding the Structure and Interaction of Hadrons

  • Calculation of spectrum of hadrons existing in nature, and exploration of their interactions

  • Determination of quark and gluon structure of nucleon and other hadrons

Project Goals

Create a unified programming environment that will enable the US lattice community to achieve very high efficiency on diverse multi-terascale architecture.

• Portable, scalable software

• High-performance optimization on two target architectures

• Exploitation and optimization of existing application base

• Infrastructure for national community

• Sharing of valuable lattice data, and data management
