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.

Eugenia, you seem to have applied a suboptimal scaling algorithm to the text that results in aliasing -- jaggies -- making it hard to read. Next time, try bicubic interpolation.
Ironic that this is mentioned in an article partly about IPP (http://www.intel.com/software/products/ipp/ipp30/), which among other things contains the implementation of some actual interpolated scaling algorithms (afaik only bilinear interpolation, at least when I last used it).
IPP is an extremely helpful toolkit. It covers anything from alpha blending to MPEG encoding, everything making use of Intel's optimized, specialized instruction sets (MMX, SIMD and what not).
It's unfortunate that Intel has not open-sourced what is arguably a potential sales-booster for Intel processors, but at $199 for a commercial license it's not exactly expensive.
