Definition

The IBM Blue Gene Supercomputer is a massively parallel system based on the PowerPC processor. A Blue Gene/L system at Lawrence Livermore National Laboratory held the number 1 position in the TOP500 list of fastest computers in the world from November 2004 to November 2007.

Discussion

Introduction

The IBM Blue Gene Supercomputer is a massively parallel system based on the PowerPC processor. It derives its computing power from scalability and energy efficiency. Each computing node of Blue Gene is optimized to achieve high computational rate per unit of power and to operate with other nodes in parallel. This approach results in a system that can scale to very large sizes and deliver substantial aggregate performance.

Most large parallel systems in the 2000–2010 time frame followed a model of using off-the-shelf processors (typically from Intel, AMD, or IBM) and interconnecting them with either an industry standard network (e.g.,...
