What is the future Chinese development track regarding HPC?
As far as the US is concerned, it has financed three 100-200 Petaflop machines by 2018, and then start work on Exascale, to be commissioned by 2023.
The only knowledge that I have is that China will upgrade Tianhe 2 to Tianhe 2A, anywhere between 100-200 Petaflops.
Of course there is the plan to reach Exascale by 2020, but I think US would lead in performance count, and may be even in top machine if China doesn't introduce one more machine above 100 Petaflops by 2018.
