Movement and placement of non-contiguous data in distributed GPU computing
… are examined. The first is a high-level 3D stencil communication library, which can automatically create a static communication plan based on the stencil and system parameters. This library is able to reduce the iteration time of a state-of-the-art stencil code by 1.45x at 3072 GPUs and 512 …

Automatic Performance Optimization of Stencil Codes
A widely used class of codes are stencil codes. Their general structure is very simple: data points in a large grid are repeatedly recomputed from neighboring values. This predefined neighborhood is the so-called stencil. Despite their very simple structure, stencil codes are hard to optimize since …

Evaluating the OpenACC API for Parallelization of CFD Applications
… or pragma statements to annotate source codes written in traditional high-level languages, is designed to permit a unified code base to serve multiple computational platforms and to simplify the transition of legacy codes to new architectures. This work analyzes the popular OpenACC …
