That's just Gelato, which only works on NVidia GPUs. However, take a look at
http://www.gpgpu.org, a repository for general purpose computing on the GPU.
Quite a bit of general purpose computing can be performed on the GPU alone.

OpenGL can be utilized as a general purpose interface to the current crop of
GPUs.  Perhaps parts of Povray can be coded to take advantage of this. The
only problem I can see is that NVidia GPUs use single-precision floating
point and calculations may not be IEEE 754 compliant. On the other hand,
NVidia is somehow able to get around this with their raytracer.
