Performance Modeling of Extreme-scale 
Parallel Architectures and Applications

 

Abstract

We begin this talk by presenting a brief introduction to performance modeling and its applications. We introduce the methodology for modeling, and novel techniques developed at Los Alamos that allow modeling of entire applications and extreme-scale parallel architectures. A number of models for apps from a scientific workload are explained and analyzed. We also show applications of modeling to performance analysis, system architecture design, system integration and application performance improvement. Resources and other relevant work in the area are shown at the end of the talk.

Bio of the Speaker

Adolfy Hoisie is a Staff Scientist, the leader of the Performance and Architecture Lab (PAL), and the Leader of the Modeling, Algorithms and Informatics Group (CCS-3) in the Computer and Computational Sciences Division at LANL. Before joining LANL in 1997 he has been a researcher at Cornell University. His area of research is performance evaluation of high-performance architectures. He published extensively, including a monograph on performance published by SIAM last year, lectured at numerous conferences and workshops, often as an invited speaker, and taught tutorials in this field at important events worldwide. He is the winner of the Gordon Bell Award in 1996.
