Abstract:
With the deployment of extreme-scale HPC systems, generating finite element meshes in parallel is now necessary to achieve scalability of the overall simulation pipeline. The parallelization of the mesh generation algorithms requires that we not only preserve the quality of the meshes generated by the sequential algorithms, but also address the requirements of robustness and scalability. Robustness of a mesh generation algorithm is its ability to correctly process any geometric domain from the class of domains it is designed for. Scalability is the ability of an algorithm to achieve performance proportional to the number of hardware cores. In this talk I will focus on tetrahedral meshing algorithms due to their ability to adapt to complex geometric domains, and, furthermore, on algorithms that are accompanied by theoretical proofs of their correctness. I will review both the theoretical foundations and the practical aspects related to the implementation of parallel meshing methods on current and emerging architectures. I will organize the methods in terms of two basic attributes: the underlying sequential techniques and the degree of coupling between the subproblems.

Speaker Bio:
Dr. Andrey Chernikov is Assistant Professor of Computer Science at Old Dominion University. He obtained his Ph.D. from the College of William and Mary in 2007. His interests include parallel computational geometry with a focus on guaranteed quality mesh generation, and image analysis in medical and bio-material modeling and simulation.
