High performance computing

IBM Power™ Systems high performance computing solutions lead the Top10 list of supercomputers in not only performance but also energy efficiency. When configured into highly scalable AIX® and Linux® clusters Power Systems offer extreme performance for demanding workloads such as computational chemistry, petroleum reservoir modeling, weather forecasting, climate modeling, and analytics.

IBM Blue Gene

IBM Blue Gene/Q delivers ultrascale performance within a standard programming environment while delivering efficiencies in power, cooling and floor-space consumption. Consistently recognized as the fastest “big data”, data intensive computing system,1 Blue Gene enables business and science to address a wide range of complex problems such as helping map the human genome, investigating medical therapies, flying airplanes, pinpointing tumors, predicting climate trends, and safeguarding nuclear arsenals. Today, with BlueGene/Q Express, a half rack configuration, this leading technology is available to a broader set of users requiring big data management that keeps them ahead of the competition.
