So now as per tradition this year was "crowned" the one that, given its characteristics, has managed to earn the title of number one supercomputer in the TOP500 of the most powerful machines in the world and this time was to lead a U.S., branded as IBM.
The fastest, most powerful supercomputer in the world, in fact, called Sequoia, was constructed by Big Blue near the Lawrence Livermore National Laboratory and runs Linux.
This is basically the revenge of IBM Whereas previous ranking in the well-known company did not figure even among the top ten while the new list of computer Big Blue there are even four.
To have had the better of everyone, including competition, however, was Sequoia, which, however, talk about it for some time, and its features leave little doubt about that.
Sequoia is based on several BQC 16 core Power processors clocked at 1.6 GHz and 45-nanometer manufacturing process, for a total of 1.5 million cores computation, occupies an entire room and has an overall weight is equal to about 30 elephants.
The performance achieved by Sequoia are of 16.3 petaflops, or more than 150% of those obtained by predecessor Japanese "K" which, in fact, had reached 10.5 petaflops.
The weblog IBM supercomputer will be used, primarily, by U.S. experts to simulate nuclear explosions and detonations with a level of detail magi reached up to now.
As regards instead the rest of the new TOP500 seems appropriate to emphasize the fact that most of the computers, well 462, are equipped with operating system based on Linux kernel, the computer using Windows are only two and the rest, instead, uses Unix or a combination of the OS listed.
