Super Core
Super Core
The Core i7 running at 50 GFLOPS, the worlds most powerful sumpercomputer is 1000 GFLOPS, why.?
I mean if $ 999 20 core i7 could overcome several supercomputer dollar millionaires, then why do people even invest on multiple computers millinare dollar.
There is more to performance supercomputers' Gflop more than numbers. One problem is that the data paths – while the Core i7 can do for periods of very short time you will have a real problem maintaining that figure. There is simply no good way to move 50 million sets of floating point numbers to be operated, and the results of those operations, and the CPU. No second to second for long periods of time. The data paths are simply not fast enough. (Assume each operand and the result is 64 bits -. Eight bytes of 50 million sets of two operands and a result number of 8 x 50 million x 3 = 1.2 billion bytes, or put another way. all the RAM in a PC 4 GB to take place around 8 million units, enough to keep the i7 occupied by just over one ten-thousandth of a second.) There is also the problem trivial partition a very large computational problem, so they can work efficiently for a number of processors slow everyone working in parts of the problem. Seymour Cray once said: This question is a bit like asking if 1,000 chickens could not do the work of a pair of oxen. "The chickens are fine, but do not really know how to make them work together yet. "
