Graphics processing unit
A graphics processing unit or GPU is a specialized circuit designed to rapidly manipulate and alter memory in such a way so as to accelerate the building of images in a frame buffer intended for output to a display...
(GPU) for molecular simulations.
In 2007, NVIDIA introduced video cards that could be used not only to show graphics but also for scientific calculations. These cards include many arithmetic units (currently up to 512) working in parallel. Long before this event, the computational power of video cards was used to accelerate calculations. What was new is that stream processing
Stream processing
Stream processing is a computer programming paradigm, related to SIMD , that allows some applications to more easily exploit a limited form of parallel processing...
made it possible to develop parallel programs in a high-level language. This technology substantially simplified programming by enabling programs to be written in C/C++.

In physics, classical mechanics is one of the two major sub-fields of mechanics, which is concerned with the set of physical laws describing the motion of bodies under the action of a system of forces...
) are among beneficial applications of this technology. The video cards can accelerate the calculations tens of times. Thus, a PC with such a card has the power similar to that of a cluster of workstations based on the common processors.
