Estimating volcanic ash emissions using retrieved satellite ash columns and inverse ash transport modelling

Autor: Brodtkorb, André R., Benedictow, Anna, Klein, Heiko, Kylling, Arve, Nyiri, Agnes, Valdebenito, Alvaro, Sollum, Espen

This paper describes the inversion procedure being used operationally at the Norwegian Meteorological Institute for estimating ash emission rates from retrieved satellite ash column amounts and a priori knowledge. The overall procedure consists of fi

Real-World Oceanographic Simulations on the GPU using a Two-Dimensional Finite-Volume Scheme

Autor: Brodtkorb, André R., Holm, Håvard Heitlo

In this work, we take a modern high-resolution finite-volume scheme for solving the rotational shallow-water equations and extend it with features required to run real-world ocean simulations. Our contributions include a spatially varying north vecto

GPU Computing with Python: Performance, Energy Efficiency and Usability

Autor: Holm, Håvard H., Brodtkorb, André R., Sætra, Martin L.

In this work, we examine the performance, energy efficiency and usability when using Python for developing HPC codes running on the GPU. We investigate the portability of performance and energy efficiency between CUDA and OpenCL; between GPU generati
