They threw a bunch of money and electricity at their flagships, but so far they’re only good for Top500 bragging rights. They didn’t really invest in the architectural framework required to get to useful exascale.

If Tianhe 2A does better with HPCG and Graph500, then maybe they’re making progress, but Taihu Light was a big step backwards from Tianhe 2 in both of those areas given its HPL FLOPS.
