Just like I suspected, building Super computers for ego-massaging. Bravo!!!
it seems you knows nothing about strategic planning. we built more roads before cars stucked in it. we have to plan ahead as supercomputers are not call centers, it requires huge amount of experiment and investment.
as to the utility, for now, it is 10%. but when the 12th 5-years-plan (2010-2015) is completed, it will be much more higher as cloud computing technology will be more matured by then. BTW, the first cloud computing center has been established in China last year, and more will be build in the future.
