Ardra: Scalable Parallel Code System to Perform Neutron and Radiation Transport Calculations. Ardra offers robust scalable solution methods for neutron and radiation transport problems in complex 3-D geometries. High resolution in space, energy, and direction are supported. Ardra has demonstrated its capability to solve systems with billions of unknowns on terascale computers with thousands of processors. The ability to model the transport of neutral particles (such as neutrons and photons) through matter is of importance to many scientific and engineering activities. Among these are reactor and shielding design, development of medical radiation treatment, and nuclear well logging applications, among others. In this work, we present a scalable, parallel code system to perform neutral particle transport calculations in three dimensions.
