"The Blended Isogeometric Discontinuous Galerkin Method in Exascale Computing"
Abstract: As computationally intensive areas like uncertainty quantification and machine learning become more popular, substantial demand emerges for numerical methods that efficiently solve complex problems. In this talk we introduce one such method called the Blended Isogeometric Discontinuous Galerkin (BIDG) method. The BIDG method offers several key capabilities that address some of these increased demands on computational models. First it offers the promise of direct, lossless, and automated coupling to, for example, computer aided designs (CAD) and geographic information systems (GIS), leading to rapidly prototyped and improved meshing. Next, BIDG preserves "exact," fully parameterized domain (and sub-feature) geometry while allowing for coarsening of meshes and grids, which leads to an efficient high-order accurate method. The BIDG method has been implemented for a number of application problems, and is being implemented with both a traditional MPI+X threading model and an asynchronous run-time system called High Performance parallelX (HPX), with early results on Intel Knights Landing chips.
