World's Top 500 Supercomputers

With 233 supercomputers churning away in the USA, it’s clear that Americans have a definite advantage over say the UK or Austria. Without removing the merits of those latter two nations to also innovate in areas of their core competences, they do face a formidable challenge.

Interestingly, Switzerland, a tiny country of 8 million, has more supercomputers than a massive country like Russia. But of course it should rather be weighed on the basis of computing cores and petaflop per second on the Linpack benchmark.

Ranking 6th on the 500 list is Switzerland with a Piz Daint CRAY XC30 system in Lugano. It features 115,984 cores of Xeon 8-core E5-2670 @ 2.6 GHz processors with a 6,271 TFlop/s Linpack performance and a theoretical peak of 7,788.85 TFlop/s. It uses NVIDIA GPUs to accelerate computation and works with a Linux platform (CLE). It’s a fact, Switzerland’s Piz Daint is the fastest supercomputer in Europe. What’s more, it has now been named the greenest petaflop computer in the world… at SC13 in Denver, Colorado (USA).  See www.top500.org for more.
