From the Foreword: "The authors of the chapters in this book are
the pioneers who will explore the exascale frontier. The path
forward will not be easy... These authors, along with their
colleagues who will produce these powerful computer systems will,
with dedication and determination, overcome the scalability
problem, discover the new algorithms needed to achieve exascale
performance for the broad range of applications that they
represent, and create the new tools needed to support the
development of scalable and portable science and engineering
applications. Although the focus is on exascale computers, the
benefits will permeate all of science and engineering because the
technologies developed for the exascale computers of tomorrow will
also power the petascale servers and terascale workstations of
tomorrow. These affordable computing capabilities will empower
scientists and engineers everywhere." - Thom H. Dunning, Jr.,
Pacific Northwest National Laboratory and University of Washington,
Seattle, Washington, USA "This comprehensive summary of
applications targeting Exascale at the three DoE labs is a must
read." - Rio Yokota, Tokyo Institute of Technology, Tokyo, Japan
"Numerical simulation is now a need in many fields of science,
technology, and industry. The complexity of the simulated systems
coupled with the massive use of data makes HPC essential to move
towards predictive simulations. Advances in computer architecture
have so far permitted scientific advances, but at the cost of
continually adapting algorithms and applications. The next
technological breakthroughs force us to rethink the applications by
taking energy consumption into account. These profound
modifications require not only anticipation and sharing but also a
paradigm shift in application design to ensure the sustainability
of developments by guaranteeing a certain independence of the
applications to the profound modifications of the architectures: it
is the passage from optimal performance to the portability of
performance. It is the challenge of this book to demonstrate by
example the approach that one can adopt for the development of
applications offering performance portability in spite of the
profound changes of the computing architectures." - Christophe
Calvin, CEA, Fundamental Research Division, Saclay, France "Three
editors, one from each of the High Performance Computer Centers at
Lawrence Berkeley, Argonne, and Oak Ridge National Laboratories,
have compiled a very useful set of chapters aimed at describing
software developments for the next generation exa-scale computers.
Such a book is needed for scientists and engineers to see where the
field is going and how they will be able to exploit such
architectures for their own work. The book will also benefit
students as it provides insights into how to develop software for
such computer architectures. Overall, this book fills an important
need in showing how to design and implement algorithms for
exa-scale architectures which are heterogeneous and have unique
memory systems. The book discusses issues with developing user
codes for these architectures and how to address these issues
including actual coding examples.' - Dr. David A. Dixon, Robert
Ramsay Chair, The University of Alabama, Tuscaloosa, Alabama, USA
