IBM System Blue Gene Solution: Blue Gene/P Application Development

This IBM® Redbooks® publication is one in a series of IBM books written specifically for the IBM System Blue Gene/P Solution. The Blue Gene/P system is the second generation of a massively parallel supercomputer from IBM in the IBM System Blue Gene® Solution series. This book provides an overview of the application development environment for the Blue Gene/P system. It is intended to help programmers understand the requirements to develop applications on this high-performance massively parallel supercomputer.

In this book, we explain instances where the Blue Gene/P system is unique in its programming environment. We also attempt to look at the differences between the IBM System Blue Gene/L™ Solution and the Blue Gene/P Solution. This book does not delve into great depth about the technologies that are commonly used in the supercomputing industry, such as Message Passing Interface (MPI) and Open Multi-Processing (OpenMP) nor tries to teach parallel programming. References are provided in those instances for you to find more information if desired.

Prior to reading this book, you must have a strong background in high-performance computing (HPC) programming. The high-level programming languages that are used throughout this book are C/C++ and Fortran95. Previous experience using the Blue Gene/L system can help you understand better some concepts in this book that we do not extensively discuss. However, several IBM Redbooks publications about the Blue Gene/L system are available for you to obtain general information about the Blue Gene/L system. We recommend that you refer to "IBM Redbooks" on page 291, for a list of those publications.
