Nuclear physics using lattice QCD in the SciDAC era

Lattice QCD currently provides our only means of solving QCD (Quantum Chromo Dynamics) - the theory of the strong nuclear force - in the low-energy regime, and thus of crucial importance for theoretical and experimental research programs in High Energy and Nuclear Physics. Under the SciDAC program, a software infrastructure has been developed for lattice QCD that effectively utilize the capabilities of the INCITE facilities. These developments have enabled a new generation of Nuclear Physics calculations investigating the spectrum and structure of matter, such as the origin of mass and spin. This software infrastructure is described and recent results are reviewed.
