Title
Scalable Parallel Octree Meshing for TeraScale Applications
Abstract
We present a new methodology for generating and adapting octreemeshes for terascale applications. Our approach combines existing methods,such as parallel octree decomposition and space-filling curves, with a setof new methods that address the special needs of parallel octree meshing.We have implemented these techniques in a parallel meshing tool called Octor.Performance evaluations on up to 2000 processors show that Octor has goodisogranular scalability, fixed-size scalability, and absolute running time. Octor also provides a novel data access interface to parallel PDE solvers andparallel visualization pipelines, making it possible to develop tightly coupledend-to-end finite element simulations on terascale systems.
