To take full advantage of the GPU I strongly suggest getting familiar 
with OpenGL ES.  The gpgpu.org website has some useful links, try:

There's a heckuvvalotta DSP processing available on the Raspi if you can 
describe your data and algorithm in graphics terms.  I think it'd be 
very good at realtime synthesis and/or effects.

As to OpenCL, not available.

Cheers,
Neil
