Russian scientists use a PC to solve complex problems tens of times faster than a supercomputers
A group of physicists from the Skobeltsyn Institute of Nuclear Physics, the Lomonosov Moscow State University, has learned to use personal computer for calculations of complex equations of quantum mechanics, usually solved with help of supercomputers. This PC does the job much faster. An article about the results of the work has been published in the journal Computer Physics Communications.
Senior researchers Vladimir Pomerantcev and Olga Rubtsova, working under the guidance of Professor Vladimir Kukulin (SINP MSU) were able to use on an ordinary desktop PC with GPU to solve complicated integral equations of quantum mechanics — previously solved only with the powerful, expensive supercomputers. According to Vladimir Kukulin, personal computer does the job much faster: in 15 minutes it is doing the work requiring normally 2-3 days of the supercomputer time.
The equations in question were formulated in the 60s by the Russian mathematician Ludwig Faddeev. The equations describe the scattering of a few quantum particles, i.e., represent a quantum mechanical analog of the Newtonian theory of the three body systems. As the result, the whole field of quantum mechanics called “physics of few-body systems” appeared soon after this. This area poses a great interest to scientists engaged in quantum mechanics, nuclear and atomic physics and the theory of scattering. For several decades after the pioneering work of Faddeev one of their main purposes was to learn to solve these complicated equations. However, due to the incredible complexity of the calculations in the case of fully realistic interactions between a system’s particles stood out of the researchers’ reach for a long time, until the supercomputers appeared.
The situation changed dramatically after the group of SINP decided to use one of the new Nvidia GPs designed for use in game consoles on their personal computer. According to one of the authors Vladimir Kukulin, Head of Laboratory of Nuclear Theory, the processor was not the most expensive, of those that you can buy for $ 300-500. The main problem in solving the scattering equations of multiple quantum particles was the calculation of the integral kernel — a huge two-dimensional table, consisting of tens or hundreds of thousands of rows and columns, with each element of such a huge matrix being the result of extremely complex calculations. But this table appeared to look like a monitor screen with tens of billions of pixels, and with a good GPU it was quite possible to calculate all of these. Using the software developed in Nvidia and having written their own programs, the researchers split their calculations on the many thousands of streams and were able to solve the problem brilliantly.
‘We reached the speed we couldn’t even dream of,’ Vladimir Kukulin said. ‘The program computes 260 million of complex double integrals on a desktop computer within three seconds only. No comparison with supercomputers! My colleague from the University of Bochum in Germany (recently deceased, mournfully), whose lab did the same, carried out the calculations by one of the largest supercomputers in Germany with the famous blue gene architecture that is actually very expensive. And what his group is seeking for two or three days, we do in 15 minutes without spending a dime.’
The most amazing thing is that the desired quality of graphics processors and a huge amount of software to them exist for ten years already, but no one used them for such calculations, preferring supercomputers. Anyway, our physicists surprised their Western counterparts pretty much. ‘This work, in our opinion, opens up completely new ways to analyze nuclear and resonance chemical reactions,’ says Vladimir Kukulin. ‘It can also be very useful for solving a large number of computing tasks in plasma physics, electrodynamics, geophysics, medicine and many other areas of science. We want to organize a kind of training course, where researchers from various scientific areas of peripheral universities that do not have access to supercomputers could learn to do on their PCs the same thing that we do.’

KeelyNet BBS Files w/bonus PDF of 'Keely and his Discoveries'
Finally, I've gotten around to compiling all the files (almost 1,000 - about 20MB and lots of work doing it) from the original KeelyNet BBS into a form you can easily navigate and read using your browser, ideally Firefox but it does work with IE. Most of these files are extremely targeted, interesting and informative, I had forgotten just how much but now you can have the complete organized, categorized set, not just sprinklings from around the web. They will keep you reading for weeks if not longer and give you clues and insights into many subjects and new ideas for investigation and research. IN ADDITION, I am including as a bonus gift, the book (in PDF form) that started it all for me, 'Keely and his Discoveries - Aerial Navigation' which includes the analysis of Keely's discoveries by Dr. Daniel G. Brinton. This 407 page eBook alone is worth the price of the KeelyNet BBS CD but it will give you some degree of understanding about what all Keely accomplished which is just now being rediscovered, but of course, without recognizing Keely as the original discoverer. Chapters include; Vibratory Sympathetic and Polar Flows, Vibratory Physics, Latent Force in Interstitial Spaces and much more. To give some idea of how Keely's discoveries are being slowly rediscovered in modern times, check out this Keely History. These two excellent bodies of information will be sent to you on CD.

'The Evolution of Matter' and 'The Evolution of Forces' on CD
Years ago, I had been told by several people, that the US government frequently removes books they deem dangerous or 'sensitive' from libraries. Some are replaced with sections removed or rewritten so as to 'contain' information that should not be available to the public despite the authors intent. A key example was during the Manhattan Project when the US was trying to finalize research into atomic bombs. They removed any books that dealt with the subject and two of them were by Dr. Gustave Le Bon since they dealt with both energy and matter including radioactivity. I had been looking for these two books for many years and fortunately stumbled across two copies for which I paid about $40.00 each. I couldn't put down the books once I started reading them. Such a wealth of original discoveries, many not known or remembered today. / Page 88 - Without the ether there could be neither gravity, nor light, nor electricity, nor heat, nor anything, in a word, of which we have knowledge. The universe would be silent and dead, or would reveal itself in a form which we cannot even foresee. If one could construct a glass chamber from which the ether were to be entirely eliminated, heat and light could not pass through it. It would be absolutely dark, and probably gravitation would no longer act on the bodies within it. They would then have lost their weight. / Page 96-97 - A material vortex may be formed by any fluid, liquid or gaseous, turning round an axis, and by the fact of its rotation it describes spirals. The study of these vortices has been the object of important researches by different scholars, notably by Bjerkness and Weyher. They have shown that by them can be produced all the attractions and repulsions recognized in electricity, the deviations of the magnetic needle by currents, etc. These vortices are produced by the rapid rotation of a central rod furnished with pallets, or, more simply, of a sphere. Round this sphere gaseous currents are established, dissymetrical with regard to its equatorial plane, and the result is the attraction or repulsion of bodies brought near to it, according to the position given to them. It is even possible, as Weyher has proved, to compel these bodies to turn round the sphere as do the satellites of a planet without touching it. / Page 149 - "The problem of sending a pencil of parallel Hertzian waves to a distance possesses more than a theoretical interest. It is allowable to say that its solution would change the course of our civilization by rendering war impossible. The first physicist who realizes this discovery will be able to avail himself of the presence of an enemy's ironclads gathered together in a harbour to blow them up in a few minutes, from a distance of several kilometres, simply by directing on them a sheaf of electric radiations. On reaching the metal wires with which these vessels are nowadays honeycombed, this will excite an atmosphere of sparks which will at once explode the shells and torpedoes stored in their holds. With the same reflector, giving a pencil of parallel radiations, it would not be much more difficult to cause the explosion of the stores of powder and shells contained in a fortress, or in the artillery sparks of an army corps, and finally the metal cartridges of the soldiers. Science, which at first rendered wars so deadly, would then at length have rendered them impossible, and the relations between nations would have to be established on new bases."
