tailieunhanh - Grid Computing P35

This book, Grid Computing: Making the Global Infrastructure a Reality, is divided into four parts. This short chapter introduces the last part, Part D, on applications for the Grid. All the chapters in the book contain material relevant for Grid applications, but in this part the focus is the applications themselves. Some of the previous chapters also cover applications as part of an overview or to illustrate a technological issue. | PART D Grid applications 35 Application overview for the book Grid computing - making the global infrastructure a reality Fran Berman 1 2 Geoffrey Fox 3 and Tony Hey4 5 1 San Diego Supercomputer Center and Department of Computer Science and Engineering University of California San Diego California United States 2Indiana University Bloomington Indiana United States 3EPSRC Swindon United Kingdom 4 University of Southampton Southampton United Kingdom INTRODUCTION This book Grid Computing Making the Global Infrastructure a Reality is divided into four parts. This short chapter introduces the last part Part D on applications for the Grid. All the chapters in the book contain material relevant for Grid applications but in this part the focus is the applications themselves. Some of the previous chapters also cover applications as part of an overview or to illustrate a technological issue. Rather than merely reviewing a list of applications in this introduction we abstract some general principles about the features of different types of applications well-suited for the Grid. Note that in addition to Chapters 37 to 43 devoted to applications in Part D Grid Computing - Making the Global Infrastructure a Reality. Edited by F. Berman A. Hey and G.

GRID APPLICATIONS Exactly what types of applications are suitable for Grid computing is still an active research area but some initial discussion is provided in Chapters 1 Section 2 introduction and 23 Section . One can identify three broad problem architectures for which Grids have been successful 1. Megacomputing problems These correspond to problems that can be divided up into large numbers of independent parts and are often termed pleasingly or embarrassingly parallel in the parallel computing
