Abstract
Fully-consistent, full-core, 3D, deterministic simulations using the orthogonal mesh code Denovo
were run on the massively parallel computing architecture Jaguar XT5. Using energy and spatial
parallelization schemes, Denovo was able to efficiently scale to over 160k processors.
Cell-homogenized cross-sections were used with Step-Characteristics, Linear-Discontinuous Finite
Element, and Tri-Linear-Discontinuous Finite Element spatial methods. It was determined that
using the finite element methods gave considerably more accurate eigenvalue solutions for large
aspect ratios meshes than those using Step-Characteristics.
