A Coarse Grained Particle Transport Solver Designed Specifically for Graphics Processing Units

Abstract

This article introduces a novel coarse-grained particle transport solver, designed specifically for streaming processor architectures. The coarse particles are transported using a Monte Carlo algorithm with a locally homogenized collision operator. Local errors introduced by the homogenization procedure and the use of (deterministic) quadratures, are described and analyzed. A brief description of how the simulation is mapped to the streaming processor (Graphics Processing Unit) is also given.
