Blog entry: Improving the performance of Nektar++ with SIMD

In modern computer architectures, the gap between processor clock speed and memory bandwidth is constantly increasing, meaning that to attain optimal performance, algorithms with a high degree of arithmetic intensity – i.e the ratio between computations performed and the amount of data transferred from the memory (DRAM) – are required. In this context, high-order finite […]

Blog entry: Automating forward and adjoint coupling in finite element geoscience simulations

In this project we are  enabling ‘coupling’ in the Firedrake stack, for the purpose of simulation, optimisation and uncertainty quantification. We are particularly interested in the type of coupling in which two or more domains of possibly distinct physical natures interact with each other via interfaces. One characteristic example of such coupling is ‘ocean-atmosphere coupling’ […]

Devito on track to run at exascale

The Devito dev team have reason to be more excited than most about DownUnder GeoSolutions (DUG) newly announced 250 petaflop (single-precision) supercomputer, known as “Bubba”. In order to make full use of these FLOPS, DUG have been developing a new seismic imaging software stack using our open source framework, Devito. Devito is an open source Domain-specific Language (DSL) […]
