There seems to be some similarity with what we want to do to accelerate 
our neural simulations (briansimulator.org), as described here:
(by the way BEP is "Brian Enhancement Proposal")
The speed-up factor we got in our experimental code with GPU is very 
substantial when there are many neurons (= large vectors, e.g. 10 000 
elements), even when operations are simple.
