Studies on the energy and deep memory behaviour of a cache-oblivious, task-based hyperbolic PDE solver
Dominic E. Charrier, Benjamin Hazelwood, Ekaterina Tutlyaeva +5
We study the performance behaviour of a seismic simulation using the ExaHyPE engine with a specific focus on memory characteristics and energy needs. ExaHyPE combines dynamically a…
