We develop a fourth-order accurate massively parallel finite-volume adaptive derivative (ADER) weighted essentially non-oscillatory (WENO) scheme for numerical solution of hyperbolic conservation laws on unstructured quadrilateral meshes. The high-order non-oscillatory discretization methodology combines fourth- and third-order accurate reconstructions through linear weights that are positive and add up to unity. The compact stencil and the one-step ADER time update make the scheme highly parallelizable on modern high-performance systems. Results from a range of test cases are provided to assess the convergence attributes, scalability on thousands of processors and test the shock capturing capability of the proposed scheme. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
