If you have a compatible nVidia graphics card (anything within the last 3 years), you should look into CUDA (http://www.nvidia.com/object/cuda_get.html). It's got a steep learning curve at first, but it's quite awesome. OpenCL is another option designed to be more cross-platform. Either way, you basically write some code in C (well...C with a few extensions and limitations) and it executes in parallel on the GPU. The current batch of nVidia GPUs support floats with both single precision and double precision, although there is a significant performance penalty with double precision for most applications. With the announcement nVidia made today, though, there will soon be new cards with much less of a performance penalty for double precision.

This type of simulation can be and is being done using CUDA. In fact a talk is being given at the upcoming nVidia technology conference on this very subject. nVidia's website won't let me create a direct link, but if you click here and then Session Catalog > Session ID 1036, you can read the abstract.

The old design, even if we could build it, does not meet current safety standards. I've heard it said that, if they knew just how narrow the flight window was for Saturn V, they would not have flown it. I don't believe that's true; but, the mere fact that someone did make that statement, is indicative of how things have changed.
