Fabian Güra: The ExaHyPE story + Profiling for ExaHyPE (part I)

The ExaHyPE project prepares exascale performance for the solution of hyperbolic partial differential equations. The current demonstrator combines adaptive mesh refinement for space-trees indexed with the Peano space-filling curve. This ensures a low memory-footprint and high efficiency. The numerical scheme is the Arbitrary High Order Derivative Discontinuous Galerkin method (ADER-DG) with finite-volume based a posteriori subcell limiting. The numerical kernels of the demonstrator are reformulated in a matrix product fashion and highly optimized towards computational performance. The objective of this thesis is the design and implementation of a profiling scheme for the computational kernels and a careful analysis concerning the relevant quantities such as energy consumption or FLOPS/s.
