The paper considers a mathematical model of the behavior of an assembly of N stars. The 'Kepler' Microsoft Windows demo application based of this model enables to perform real-time simulation of star clusters dynamics for N~=2500. Such performance rate is possible through the use of the Intel Integrated Performance Primitives (IPP) library. The paper also estimates the efficiency of the IPP application and provides an example of C-code with the IPP functions calls. Computer-simulated images of the spiral galaxy forming process, as well as the real galaxies photos, are presented.

'Real time' means more than 20 frames (or integration steps in our case) per second. So we may see the galaxy evolution as a movie (many times accelerated, of course). I thought it's clear.
