Parallel Computing and Programming

This book takes the reader on a tour of the fast-growing area of high performance computing and the optimization of hybrid programs, focuses on optimization for clusters consisting of the Intel Xeon processor.

Parallel machines provide a wonderful opportunity for applications with large computational requirements. Effeective use of these machines, though, requires a keen understanding of how they work. In only a few years, many standard software products will be based on concepts of parallel programming implemented on such hardware, and the range of applications will be much broader than that of scientific computing, up to now the main application area for parallel computing.

This book is intended for anyone who has heard about the many benefits of using HPC (such as streamlining processes or saving money). This book explains what HPC is and shows how it can help you or others within your company.

This book is devoted to the investigation of a special topic in theoretical computer science - Parallel Computing and Programming as an abstract measure of the complexity of parallel computing problems.

XcalableMP is a directive-based parallel programming language based on Fortran and C, supporting a Partitioned Global Address Space (PGAS) model for distributed memory parallel systems. This open access book presents XcalableMP language from its programming model and basic concept to the experience and performance of applications described in XcalableMP.
