It's also nice to check out CUDA if you have a Nvidia card. You can run parts of your code very easy on the GPU gaining a lot of speed.

If I'm a "normal" web programmer, how much of a step up is Cuda programming going to be? I've got some geospatial functions (like point-in-polygon) that might benefit from being run on the GPU.

http://sysweb.cs.toronto.edu/publication_files/0000/0247/icc... is a good example of the kinds of things I'm looking at but I only barely grasp the concepts in the paper itself.

As far as I know Cuda is only available as a C bin.

CUDA can be programmed in C, C++, Fortran, Haskell, .NET, Java and any other language with backends than can spit out PTX, hence why researchers always favoured it over OpenCL.

OpenCL now has SPIR

I know, it was a response to those developeers wanting to stay away from OpenCL C code or using translators that would generate OpenCL C from their languages of choice.

Lets see if they are still on time to change the wave.

I think there's a decent MOOC on udacity; or at least there was at some point. Linear algebra helps a bit, but you can probably pick up most of what you need to get started.
