"NVIDIA CUDA
Revolutionary GPU Computing
NVIDIAR CUDA™ technology is a fundamentally new computing architecture for
the GPU to solve complex computational problems across consumer, business,
and technical industries.  CUDA (compute unified device architecture)
technology gives data-intensive applications access to the tremendous
processing power of NVIDIA graphics processing units (GPUs) through a
revolutionary computing architecture unleashing entirely new capabilities. 
Providing orders of magnitude more performance and simplifying software
development through the standard C language, CUDA technology enables
developers to create solutions for data-intensive processing to produce
accurate answers, in less time.


If you are interested in developing with CUDA please join our registered
developer program to get started.


What is CUDA technology?

GPU computing with CUDA technology is an innovative combination of
computing features in next generation NVIDIA GPUs that are accessed through
a standard ‘C’ language.  Where previous generation GPUs were based on
“streaming shader programs”, CUDA programmers use ‘C’ to create programs
called threads that are similar to multi-threading programs on traditional
CPUs.  In contrast to multi-core CPUs, where only a few threads execute at
the same time, NVIDIA GPUs featuring CUDA technology process thousands of
threads simultaneously enabling a higher capacity of information flow.

One of the most important innovations offered by CUDA technology is the
ability for threads on NVIDIA GPUs to cooperate when solving a problem.
  By enabling threads to communicate, CUDA technology allows
applications to operate more efficiently.  NVIDIA GPUs featuring CUDA
technology have a Parallel Data Cache that saves frequently used
information directly on the GPU.  Storing information on the GPU allows
computing threads to instantly share information rather than wait for data
from much slower, off-chip DRAMs.  This advance in technology enables users
to find the answers to complex computational problems in real-time."

Maybe someone could write a driver for Vista
