Cray XC50 NS-05 "ATERUI II" to fully model the galaxy

Japan's newest supercomputer - the Cray XC50, aka ATERUI II - has gone online, and will use its 40,000 cores and 3 petaflops of processing power to simulate everything from the birth of the universe to the interior of stars:

Oh, and:

With its superior computational capability, ATERUI II will tackle problems too difficult for previous computers. For example, ATERUI II is able to calculate the mutual gravitational forces among the 200 billion stars in the Milky Way Galaxy, rather than bunching them into groups of stars the way other simulations do. In this way ATERUI II will generate a full-scale high-resolution model of the Milky Way Galaxy.
I'm looking forward to seeing that. :)

There's also a short video about it on YouTube here:
