Gadget in extremis: Nvidia GPU-powered supercomputer
Well, if you are the Swiss National Supercomputing Center (CSCS) – a major European institution for computational research – you might throw a petaflop of GPU-accelerated processing power at the problem.
It is building a new Cray XC30 supercomputer – dubbed “Piz Daint”, apparently after a mountain in the Swiss Alps – that will be extended with GPU accelerators. The goal is to expand the depth of the center’s research in weather modeling.

With NVIDIA Tesla K20X GPU accelerators (right), Piz Daint will have more than 1 petaflops of performance – that’s 1,000 trillion floating point operations per second – which is expected to make it the fastest GPU accelerator-based scientific supercomputer in Europe when it becomes operational in early 2014.
Based on the NVIDIA Kepler architecture – the world’s fastest and most energy-efficient high performance computing architecture – the Tesla GPUs will dramatically accelerate performance at an affordable cost. This is key as running complex, compute-intensive simulations of large-scale environmental phenomenon accurately takes massive computing resources.
