Porting a Coarse-Mesh Neutron Diffusion Code on a Cray T3D Massively Parallel Computer

摘要

A coarse-mesh code for time-dependent multigroup neutron diffusion calculations has been implemented on a Cray-T3D massively parallel machine. The algorithm, based on a Alternative Direction Implicit method is well adapted for two different parallelization schemes. The code parallelization and the first results of the simulation for a classical nuclear engineering benchmark problem are here presented.
