My wife worked on this a bit with Adam (https://twitter.com/#!/acfoltzer https://twitter.com/#!/acfoltzer) and Ryan. There is a pending submission to ICFP. The reason they went with CUDA was to plug into Accelerate's existing framework without redeveloping the entire wheel. As meric mentioned, Accelerate is a pain to do anything with and you can bet dollars to do syntax that this package will generate the hard parts for you. IIRC, ParFunk also has some nice framework in place for distributed computation (though I'm not certain it's completely in working order yet).
