Supercomputer Ranking and Density

Top 500 Supercomputer Sites publishes a cool overview of the 500 most powerful (measured in Terra Flops) worldwide.

Here are the top 10 with five computers from the US, two from Germany and one each from China, Japan and Switzerland.

Looking at the whole list (500 super computers) the country distribution is as follows with the US dominating followed by China and Japan.

An a per capita basis, the US is still leading followed by Switzerland and Norway. The relatively low density of Germany and Japan may be surprising.
