We study the performance behaviour of a seismic simulation using the ExaHyPE engine with a specific focus on memory characteristics and energy needs.  ...  In cases where memory-intense and computationally expensive tasks overlap, ExaHyPE's cache-oblivious implementation can exploit deep, non-inclusive, heterogeneous memory effectively, as main memory misses  ...  Acknowledgements The authors appreciate support received from the European Union Horizon 2020 research and innovation programme under Rannabauer for the support on running the seismic benchmarks.  ...

We study the performance behaviour of a seismic simulation using the ExaHyPE engine with a specific focus on memory characteristics and energy needs.  ...  The expensive tasks and thus the whole code benefit from AVX vectorization, although we suffer from memory access bursts. A frequency reduction of the chip improves the code's energy-to-solution.  ...  Thanks are due to all members of the ExaHyPE consortium who made this research possible; notably J.-M. Gallard for integrating aggressively optimized compute kernels into ExaHyPE and K. Duru, A.-A.  ...

Automated optimization of numerical methods for partial differential equations

The focus is on numerical methods based on unstructured meshes, such as the finite element method.  ...  A single simulation may last hours, days, or even weeks to reach a certain level of accuracy, despite running on large-scale parallel architectures.  ...  Applying Loop Fusion and Loop Tiling is More Difficult than Commonly Assumed We show in Listing 6 the "skeleton" of a typical PDE solver based on unstructured meshes.  ...

Finally, we add to previous studies a comprehensive network analytic evaluation of the generative model based on hyperbolic geometry.  ...  simulators such as ODE based and SSA based solvers.  ...  Given a formal model of a system and a property specification, the task is to explore the state space and verify whether or not the property is satisfied by the model.  ...
