Some people here seems to have the IQ of a 12 years old (Strange as they all say how high the Chinese IQ were) and do not understand why Tianhe-2 is wasting it bandwidth. Let me explain one more time.
Process to power ration is not "Processor" to power ratio. What does it means? Let assume Tianhe-2 can only have 10 process per year to process. Then the economical level of Tianhe-2 would be depending on the task perform by Tianhe2 which mean if almost all those process occupied Tianhe2 processing power, then and only then said equipment would be considered striking the necessarily power to process. Because the power consumption remain slightly constant, and it would have lost value if Tianhe was used to process information only requiring half of its computation power. However, according to Statistical sampling model. The standard deviation of the task would have the majority of process will only require a fraction of Tianhe-2 processing power.
Process 1 - require 15% of Tianhe-2 Processing power
Process 2 - require 30% of Tianhe-2 Processing power
Process 3 - require 35% of Tianhe-2 Processing power
Process 4 - require 40% of Tianhe-2 Processing power
Process 5 - require 45% of Tianhe-2 Processing power
Process 6 - require 50% of Tianhe-2 Processing power
Process 7 - require 50% of Tianhe-2 Processing power
Process 8 - require 55% of Tianhe-2 Processing power
Process 9 - require 75% of Tianhe-2 Processing power
Process 10 - require 95% of Tianhe-2 Processing power
This 10 process satisfied the standard deviation (SD) model. So, theoretically, tianhe-2 would spend 65% of its time processing something slightly less than half to more slightly more than half its capacity. But still, it have to consume the power require for the computer to function.
9 out of 10 times the Tianhe-2 power is wasted because essentially you pay for full price for using something in half most of the time.
Now, you can still say you need Tianhe-2 to process the one that need majority of its power (Process 10). But in ascent, no. Because process and computer power can be either serial or parallel. A process can either break down into 2 or more and process them separate for the same result, require longer time but less processing power. Or alternatively you can connect 2 or more supercomputers to parallel process the task. Hence in effect, you don't actually need supercomputer like Tianhe-2.
Is this some kind of joke or something?
