Overview

Although the highly anticipated petascale computers of the near future will perform at an order of magnitude faster than today s quickest supercomputer, the scaling up of algorithms and applications for this class of computers remains a tough challenge. From scalable algorithm design for massive concurrency toperformance analyses and scientific visualization, Petascale Computing: Algorithms and Applications captures the state of the art in high-performance computing algorithms and applications. Featuring contributions from the world s leading experts in computational science, this edited collection explores the use of petascale computers for solving the most difficult scientific and engineering problems of the current century. Covering a wide range of important topics, the book illustrates how petascale computing can be applied to space and Earth science missions, biological systems, weather prediction, climate science, disasters, black holes, and gamma ray bursts. It details the simulation of multiphysics, cosmological evolution, molecular dynamics, and biomolecules. The book also discusses computational aspects that include the Uintah framework, Enzo code, multithreaded algorithms, petaflops, performance analysis tools, multilevel finite element solvers, finite element code development, Charm++, and the Cactus framework. Supplying petascale tools, programming methodologies, and an eight-page color insert, this volume addresses the challenging problems of developing application codes that can take advantage of the architectural features of the new petascale systems in advance of their first deployment.

Bader has done an excellent job of creating a collection that holds together and covers a broad topic very well. At the same time, Petascale Computing remains accessible to anyone with HPC or scientific application experience. The end result educates and informs our journey through petascale and into exascale, while serving to motivate us to travel as fast as we can toward the goal. John West, HPCwire This is an exciting period for HPC and a period which promises unprecedented discoveries at scale, which can provide tangible benefits for both science and society. This book provides a glimpse into the challenging work of petascale s first wave of application and algorithm pioneers, and as such, provides an important context for both the present and the future. Francine Berman, Director, San Diego Supercomputer Center, La Jolla, California, USA This book provides a quick introduction on how the next generation of supercomputers will be used and a look into the future of large-scale scientific computing. The authors present many of the issues and challenges that face computational scientists in the effective use of the fastest computers. Jack Dongarra, University of Tennessee, Knoxville, USA The collection of articles in this book provides an excellent introduction to the state of the art in high-performance computing. Written by some of the best practitioners in the field and focused on real applications, it clearly illustrates the complex interplay between application characteristics, programming languages and libraries, and machine characteristics. Any person involved in the development of high-performance computing software will benefit from reading this timely book. Marc Snir, University of Illinois, Urbana-Champaign, USA A milestone book on petascale computing. Guojie Li, Chinese Academy of Sciences, Beijing There is a need for this book. Petascale systems are arriving in 2008 or so, and theret
