title = "Approaches to load balancing massively parallel transport sweeps on unstructured grids",
abstract = "PDT, Texas A&M{\textquoteright}s massively parallel deterministic transport sweep code, has the capability to sweep on unstructured grids. In order to combat the inherent imbalance (inequivalent amount of work per processor) of unstructured meshes for transport sweeps, we implemented two automated load balancing algorithms: the original load balancing algorithm and the load balancing by dimension algorithm. In a parametric study, the original load balancing algorithm improved balance by a maximum of 89% with a mean improvement of 16.9%, while the load balancing by dimension algorithm improved balance by a maximum of 93.8% with a mean improvement of 32.3%.",
