Complex systems modeling and simulation approaches are being
adopted in a growing number of sectors, including finance,
economics, biology, astronomy, and many more. Technologies
ranging from distributed computing to specialized hardware are
explored and developed to address the computational requirements
arising in complex systems simulations.
The aim of this book is to present a representative overview of
contemporary large-scale computing technologies in the context of
complex systems simulations applications. The intention is to
identify new research directions in this field and to provide a
communications platform facilitating an exchange of concepts, ideas
and needs between the scientists and technologist and complex
system modelers. On the application side, the book focuses on
modeling and simulation of natural and man-made complex
systems. On the computing technology side, emphasis is placed
on the distributed computing approaches, but supercomputing and
other novel technologies are also considered.
