Towards Application Variability Handling with Component Models: 3D-FFT Use Case Study

摘要

To harness the computing power of supercomputers, HPC application algorithms have to be adapted to the underlying hardware. This is a costly and complex process which requires handling many algorithm variants. This paper studies the ability of the component model L~2C to express and handle the variability of HPC applications. The goal is to ease application adaptation. Analysis and experiments are done on a 3D-FFT use case. Results show that L~2C, and components in general, offer a generic and simple handling of 3D-FFT variants while obtaining performance close to well-known libraries.
