IBM Blue Gene/Q

Key technologies and applications of the IBM Blue Gene/Q supercomputer are described in an overview article and 14 technical papers. This highly scalable system can achieve a performance of 20 PFLOPS and yet top the list of the most power-efficient supercomputers. Papers in this issue describe the compute chip, the five-dimensional network that interconnects the compute nodes, the packaging and power technologies that support more than 1,000 nodes in a rack, the hardware and software architectures, the methodologies for high performance and low power, and the initial experiences with applications run by Lawrence Livermore and Argonne National Laboratories as well as Columbia and Edinburgh Universities.
