Parallelization of Python on GPU?

I can't help you with that, but I would like to point out that GPUs 
typically don't support IEE-754 maths, which means that while they are 
likely significantly faster, they're also likely significantly less 
accurate. Any any two different brands/models of GPU are likely to give 
different results. (Possibly not *very* different, but considering the mess 
that floating point maths was prior to IEEE-754, possibly *very* different.)

Personally, I wouldn't trust GPU floating point for serious work. Maybe for 
quick and dirty exploration of the data, but I'd then want to repeat any 
calculations using the main CPU before using the numbers anywhere :-)
