Re: [Haskell-cafe] Large, numerical calculations in Haskell

Emil Hedevang writes:

Hi Haskell Cafe,

I need to perform very large numerical computations requiring tens of GB of

memory. The computations consist essentially of generation of random numbers and discrete convolutions of large arrays of random numbers with somewhat 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.
