I have read the papers about the accelerate package that provides a
high-level interface to nvidia's cuda library and am very intrigued.
However, I have some start-up problems. Is this the right place for such
In particular, I'm having trouble with lifting and unlifting. From what I
understood, I should be able to use unlift to get an Int from an Exp (Plain
Int), but when I try, for example,
(unlift . lift) (1::Int) :: Int
ghci complains with
"No instance for (Unlift Int)".
I have the latest versions of accelerate (accelerate-0.9.0.1) and ghc
I think I'm missing something obvious, so if any of you could point it out
to me I would be glad.
