smaller kernel arrays. Should I use Haskell and call some C libraries when 
necessary? Should I just write everything in C? Or should I use e.g. Chapel 
(chapel.cray.com)?

Hi Emil,

The first place I would look would be repa http://repa.ouroborus.net/. IIRC it 
supports discrete convolutions and repa folks seem quite responsive.

Dominic.

PS I am planning to use repa to solve PDEs and address, at least 
partially, "the curse of dimensionality" with it.
