Software Prefetching for Unstructured Mesh Applications

Robust Parallel Adaptive Mesh Refinement Software Library for Unstructured Meshes

Compiler Optimizations for Industrial Unstructured Mesh CFD Applications on GPUs

Graphical Processing Units (GPUs) have shown acceleration factors over multicores for structured mesh-based Computational Fluid Dynamics (CFD). However, the value remains unclear for dynamic and irregular applications. Our motivating example is HYDRA, an unstructured mesh application used in production at Rolls-Royce for the simulation of turbomachinery components of jet engines. We describe th...

Efficient unstructured mesh generation for marine renewable energy applications

Renewable energy is the cornerstone of preventing dangerous climate change whilst maintaining a robust energy supply. Tidal energy will arguably play a critical role in the renewable energy portfolio as it is both predictable and reliable, and can be put in place across the globe. However, installation may impact the local and regional ecology via changes in tidal dynamics, sediment transport p...

Image-based Unstructured 3d Mesh Generation for Medical Applications

We present a dimension-independent algorithm for non-uniform meshing of voxel geometries, e.g. stemming from segmented medical images. The basic algorithms uses spacetrees (generalized octrees for arbitrary dimension) to build a hierarchical representation of the image information. The resolution of the spacetree can depend on several parameters, such as homogeneity of the material, or applicat...

Software Data Prefetching for Software Pipelined Loops

This paper focuses on the interaction between software prefetching (both binding and nonbinding prefetch) and software pipelining for statically-scheduled machines. First, it is shown that evaluating software pipelined schedules without considering memory effects can be rather inaccurate due to stalls caused by dependences with memory instructions (even if a lockup-free cache is considered). It...
