"The LP2 library: an easy way to multi-thread programs dealing with unstructured meshes"

Abstract:

"As of today, programers willing to multi-thread their code are provided with many choices like OpenMP, UPC or various compilers featuring automated parallelization. Unfortunately, they provide no easy way to handle loops that perform indirect  memory accesses, which are common ground when dealing with unstructured meshes. The LP2 allows for parallelization of such loops with the help of dynamic scheduling and space filling curves.If I have enough time, I will also discuss HEXOTIC,  an automated hexahedral mesh generator combining octree,  dual-mesh  and buffer-layers. Even though many methods have been  suggested to meet  the challenge of all-hexahedral meshing, octree-based  methods remain the most efficient from an  engineering point of view. As  of today, its speed and robustness are still  unmatched. This paper  presents advances made in the Hexotic project, especially  in terms of  automation, sharp angles meshing  and adaptation."

Bio:

"I have been working on automated mesh generation for twelve years in the Gamma team at INRIA / FRANCE. My main research subjects are, hexahedral meshing, adaptive meshing and surface meshing. I am also working on multi-threading as a side project"
