American science uses 16 simulated black hole tests on LinuxPS3

Article title: U.S. scientists use 16 LinuxPS3 simulated black hole experiments. Linux is a technology channel of the IT lab in China. Some basic categories include desktop applications, Linux system management, kernel research, embedded systems, and open source systems. according to foreign media reports, most people will run home with the newly bought Sony PS3 game machine, they can't wait to kill aliens in "Resistance: the destruction of mankind", or start fighting in "vrwarrior 5. But the American physicist Gaurav Khanna is a heterogeneous one-he built a supercomputer on the PS3 to simulate black hole collisions.

Canner currently has 16 PS3, all of which are connected by him, providing the same computing power as a 400-node supercomputer. The device, called the gravity grid, was used by the Department of Physics at the University of maserjuna to simulate the activity of a large black hole. This project attempts to estimate the characteristics of gravity waves generated during the collision of two black holes. Gravity waves are the "ripple" that is transmitted at the speed of light in time and space ".

Einstein's general theory of relativity had theoretically predicted the existence of gravity waves, but they were not directly observed. Canner installs Linux OS on the PS3 to run his simulation data on this device. The efficiency of this gaming platform is higher than that of high-end computers for complex research and computation, thanks to the cell chips developed by IBM to handle high-end game features.

Kanna wrote: "Linux can turn any system into a multi-functional computer. to make it work for me, I have to run my own code on it for astronomical physics research. The difficulty of this kind of work is to ensure that my own algorithms can be quickly operated on this platform, which means that I must optimize the writing code of the Linux operating system, in this way, it can take advantage of the new features of the supercomputer system."

The appearance of the 16 PS3 has not changed. They are only connected with a inexpensive 10-Gigabit Ethernet switch. Kanna pointed out: "In general, the performance of a PS3 game machine. It is equal to 25 IBM Blue Gene supercomputer nodes that are higher than the most advanced existing desktop ."
