Earth Simulator vs 30000 PS3

The Stanford University in the United States has been doing to analyze proteins that cause intractable diseases such as cancer, Alzheimer's, Parkinson's disease, etc. Distinguished computing project "Folding @ Home" that forms the world's largest supercomputers worldwide In the number of Windows machines that PS3 participates in, the number of computers is 1/5, which means that it has attained over 3 times the computing speed.

By the way, I do not know how fast it is, so I decided to compare it with "Earth Simulator" as a comparison target.

Details are as follows.

According to this page, the computing speed as of March 25, 2007 17:17:59 is 154 TFLOPS (TeraFLOPS) by Windows machines with 160 thousand 1507 CPUs, whereas PS 3 with 30272 CPUs is 481 TFLOPS It is said that it is becoming.

This is the measurement result.


And 481 TFLOPS is actually more than 13 times the processing speed of "Earth Simulator" installed at Ocean Research and Development Organization, 35.86 TFLOPS. Also,Past news reportsAccording to it, it seems that "Earth Simulator" took 50 billion yen to build, but if it is PS 3, it is 2259 units to realize the same performance and only 20 million yen if it is 20GB model (49,990 yen) To That's unbelievable. If you purchase with Yodobashi camera, it is reduced by 10% and it is profitable.

The CPU "Cell" installed in the PS3 is a multi-core CPU with a total of nine cores in one CPU, and by operating multiple cores in parallel, physical computation, simulation, animation, voice processing, etc. It is likely to demonstrate performance. The following links are detailed about Cell.
