Questions tagged [accelerate-haskell]

Accelerate defines an embedded language of array computations for high-performance computing in Haskell. Computations on multi-dimensional, regular arrays are expressed in the form of parameterised collective operations (such as maps, reductions, and permutations). These computations are online-compiled and executed on a range of architectures.

Converting accelerate's A array representation to repa's U array representation

I'd like to convert an accelerate array to a repa array, before then using writeImageToBMP from repa-io to write the array to a BMP file. Ignore the fact that there exists such a function in accelerate-io, I'm just using it as an example of the…
