Creating the BlueGene/L supercomputer from low-power SoC ASICs

An overview of the design aspects of the BlueGene/L chip, the heart of the BlueGene/L supercomputer, is presented. Following an SoC approach, processors, memory and communication subsystems are integrated into one low-power chip. The high-density system packaging of the BlueGene/L system provides better power and cost performance.
