Regular, shape-polymorphic, parallel arrays now in AUR

Repa, a new library for multi-dimensional automatically-parallel arrays in Haskell, is now available in Arch Linux via AUR.  Such arrays may be converted to and from bytestrings, and written out in various formats. Example algorithms are available, including fft2d, matmult, and laplace, along with an algorithm library. The library may prove useful for scientific and numerical computing, where high level languages, with good parallel performance, should shine.

More information about Repa is available:

• In the release announcement
• In the accompanying ICFP paper.
• And in the haddock documentation.

The full set of packages are available in AUR:

• haskell-repa
• haskell-repa-io
• haskell-repa-bytestring
• haskell-repa-algorithms
• repa-examples
