hi, i'm using now 10 yuan = 1 euro, just for ease of calculation:
2 billion RMB = 2 billion yuah (assumption) = 200 million euro
200 mln / 1920 nodes = 104,166.666666667 euro a node
104k euro a node in short. That's soon 200k dollar.
It doesn't matter what gets delivered for that, if it has just 16 cores,
then it is a factor 5-10 too expensive.
Even if there is 4 expensive FPGA cards in each node or so,
that just doesn't matter.
Additional to that, 128 GB DDR2-800 ECC ram is real real cheap.
We all know this typical government problem of overpaying for hardware.
But it sure means there was enough budget for windows.

A while back a customer of PathScale issued a press release about how
they were running Windows on their supercomputer, with InfiniPath

drivers.
So I was curious about the Dawning 5000A... the previous
supercomputers
in this series ran Linux. But the top500 entry trumpets Windows.
Well...

This press release says it runs Linux and Windows. That's a bit more
credible; I wonder if they actually had to buy the Windows software?
