Energy efficiency of finite difference algorithms on multicore CPUs, GPUs, and Intel Xeon Phi processors
Satya P. Jammy, Christian T. Jacobs, David J. Lusher +1
In addition to hardware wall-time restrictions commonly seen in high-performance computing systems, it is likely that future systems will also be constrained by energy budgets. In…
Automated Tiling of Unstructured Mesh Computations with Application to Seismological Modelling
Fabio Luporini, Michael Lange, Christian T. Jacobs +3
Sparse tiling is a technique to fuse loops that access common data, thus increasing data locality. Unlike traditional loop fusion or blocking, the loops may have different iteratio…
Surface-sampled simulations of turbulent flow at high Reynolds number
Neil D. Sandham, Roderick Johnstone, Christian T. Jacobs
A new approach to turbulence simulation, based on a combination of large-eddy simulation (LES) for the whole flow and an array of non-space-filling quasi-direct numerical simulatio…
Performance evaluation of explicit finite difference algorithms with varying amounts of computational and memory intensity
Satya P. Jammy, Christian T. Jacobs, Neil D. Sandham
Future architectures designed to deliver exascale performance motivate the need for novel algorithmic changes in order to fully exploit their capabilities. In this paper, the perfo…
OpenSBLI: A framework for the automated derivation and parallel execution of finite difference solvers on a range of computer architectures
Christian T. Jacobs, Satya P. Jammy, Neil D. Sandham
Exascale computing will feature novel and potentially disruptive hardware architectures. Exploiting these to their full potential is non-trivial. Numerical modelling frameworks inv…
Connecting web-based mapping services with scientific data repositories: collaborative curation and retrieval of simulation data via a geospatial interface
Christian T. Jacobs, Alexandros Avdis
Increasing quantities of scientific data are becoming readily accessible via online repositories such as those provided by Figshare and Zenodo. Geoscientific simulations in particu…
