: Describes the state of the art in hardware and software tools that are commonly used for monitoring and measuring performance and managing large quantities of data Discusses modern approaches to computer performance benchmarking and presents results that offer valuable insight into these studies Explains how researchers deduce accurate performance models from raw performance data or from other high-level characteristics of a scientific computation Explores ongoing research into automatic and semi-automatic techniques for optimizing computer programs to achieve superior performance on any computer platform Provides examples that show how the appropriate analysis of performance and some deft changes have resulted in extremely high performance Performance analysis has grown into a full-fledged, sophisticated field of empirical science. Describing useful research in modern performance science and engineering, this book helps real-world users of parallel computer systems to better understand both the performance vagaries arising in scientific applications and the practical means for improving performance.
