A new list was published on top500.org. It might be noteworthy that the NSA, Google, Amazon, Microsoft etc. are not submitting information to this list. Currently, the top two places are occupied by China, with a comfortable 400% head-start in peak-performance and 370% Rmax performance to the 3rd place (Switzerland). US appears on rank 4, Japan on rank 7, and Germany is not in the top ten at all.
All operating systems in the top-10 are Linux and derivates. It seems obvious that, since it is highly optimized hardware, only operating systems are viable which can be fine-tune (so, either open source or with vendor-support for such customizations). Still I would have thought that, since a lot of effort needs to be invested anyway, maybe other systems (BSD?) could be equally suited to the task.
takyon: TSUBAME3.0 leads the Green500 list with 14.110 gigaflops per Watt. Piz Daint is #3 on the TOP500 and #6 on the Green500 list, at 10.398 gigaflops per Watt.
According to TOP500, this is only the second time in the history of the list that the U.S. has not secured one of the top 3 positions.
The #100 and #500 positions on June 2017's list have an Rmax of 1.193 petaflops and 432.2 teraflops respectively. Compare to 1.0733 petaflops and 349.3 teraflops for the November 2016 list.
[Update: Historical lists can be found on https://www.top500.org/lists/. There was a time when you only needed 0.4 gigaflops to make the original Top500 list — how do today's mobile phones compare? --martyb]

Government's role is NOT supercomputing.
Government's role is snooping on its citizens. For prevention and early discovery of thought crime.
Supercomputers are merely a means to that necessary end. It's for our own good.
Plus, supercomputers can help with weather forecasting.

What do you think #5 on the list is mostly used for? I'll give you a clue: it's not for weather forecasting.

Department of Energy doesn't sound so scary. What could they possibly model, involving enormous amounts of energy, that could be more important than weather? And no need to model on supercomputers. Just do above ground tests in New Jersey.

Quiet you fool!
Our only hope is that Rick Perry never finds out that he's in charge of the nukes!
