Title:
Node-Level optimization of a 3D Block-Based Multiresolution Compressible Flow Solver with Emphasis on Performance Portability 
Abstract:
Despite the enormous increase in computational power in the last decades, the numerical study of complex flows remains challenging. State-of-the-art techniques to simulate hyperbolic flows with discontinuities rely on computationally demanding nonlinear schemes, such as Riemann solvers with weighted essentially non-oscillatory (WENO) stencils and characteristic decompositioning. To handle this complexity the numerical load can be reduced via a multiresolution (MR) algorithm with local time stepp...    »
