PENNANT: an unstructured mesh mini-app for advanced architecture research

摘要

This paper describes PENNANT, a mini-app that operates on general unstructured meshes (meshes withrnarbitrary polygons), and is designed for advanced architecture research. It contains mesh data structures andrnphysics algorithms adapted from the Los Alamos National Laboratory radiation-hydrodynamics code FLAGrnand gives a sample of the typical memory access patterns of FLAG. The basic capabilities and optimizationrnapproaches of PENNANT are presented. Results are shown from sample performance experiments run onrnserial, multicore, and graphics processing unit implementations, giving an indication of how PENNANT canrnbe a useful tool for studies of new architectures and programming models.
