A team of physicists from the Moscow State University R&D Institute of Nuclear Physics has managed to utilise personal computers to conduct complex quantum mechanics calculations, usually only manageable by supercomputers.
The research, which shows the experimental PC has proven to be faster than its more expensive counterpart, is available in the latest edition of the Computer Physics Communications journal.
An ordinary desktop PC with GPU was used for calculations in few-body quantum scattering. The researchers stated that it took their PC fifteen minutes to perform the same calculations that a supercomputer would require two to three days to complete.
“We reached the speed we couldn't even dream of. The program computes 260 million of complex double integrals on a desktop computer within three seconds only,” said Vladimir Kukulin, Head of Laboratory of Nuclear Theory of MSU.
“This work, in our opinion, opens up completely new ways to analyse nuclear and resonance chemical reactions. 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,” he added.
