Petascale computers will have an order of magnitude faster than the speediest supercomputer. This book covers topics from scalable algorithm design for massive concurrency to scientific visualization and performance analysis.

Petascale computers, which are expected to come to fruition around 2008 to 2012, will have an order of magnitude faster than today's speediest supercomputer. Along with this magnificent feat of engineering, however, comes anticipation of a greater challenge: scaling up algorithms and applications for these leadership class supercomputing systems. From scalable algorithm design for massive concurrency to scientific visualization and performance analysis, "Petascale Computing" presents a wide range of topics that are important for this exciting new area. The book features a collection of contributions from international researchers who are considered early leaders in designing applications for this field.
