The GPU jump

General-purpose graphical processing units (GPGPUs) have been making inroads into HPC applications, but with the release of chips optimised for scientific computations rather than just graphics processing, this branch is poised to make major market inroads. Paul Schreier examines what's behind this upcoming jump in performance, and its implications

Towards exascale

Arthur 'Buddy' Bland, project director for the Oak Ridge Leadership Computing Facility (OLCF) at Oak Ridge National Laboratory, describes the rise from terascale to petascale computing and the road to exascale

Facing the heat

In the design of their servers, computer manufacturers are combating the need for power at every level: from processors, to power supplies, to cooling methods and everything in between. Paul Schreier checked with some major suppliers to investigate what they've been up to
