HPC: GPU PROCESSING
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
HPC: WEATHER AND CLIMATE
Let's talk about the weather
Stephen Mounsey discovers how high performance computing contributes to atmospheric science and improves the accuracy of weather forecasts
