Blue Gene Volume 49, Number 2/3, 2005 Click to enlarge
RD 49-2/3
In November 2004, the IBM Blue Gene computer became the fastest supercomputer in the world. Unprecedented performance was achieved in a compact low-power design. The 22 papers contained in this issue present the hardware and software designs, as well as some early applications and performance measurements. All key hardware systems from the compute chip to the full supercomputer are covered. The software architecture and systems are described, and initial work with applications, particularly those for molecular dynamics, is presented.
