An Embedded Language for Accelerated Array Computations
For more details, please have a look at our recent paper Accelerating Haskell Array Codes with Multicore GPUs. There are some slightly outdated slides and a video of a talk that I gave at the Haskell Implementors Workshop 2009 (in Edinburgh): Haskell Arrays, Accelerated (Using GPUs).
A simple example
As a simple example, consider the computation of a dot product of two vectors of single-precision floating-point numbers:
dotp :: Acc (Vector Float) -> Acc (Vector Float) -> Acc (Scalar Float) dotp xs ys = fold (+) 0 (zipWith (*) xs ys)
Except for the type, this code is almost the same as the corresponding Haskell code on lists of floats. The types indicate that the computation is off-loaded to a GPU.
Haddock documentation is included in the package and linked from the
Hackage page. Furthermore, the source package contains a few simple
examples in the
The idea behind the HOAS (higher-order abstract syntax) to de-Bruijn conversion used in the library is described separately.
