Data Parallel Haskell and Repa for GHC 7.2.1
As an add-on to the just released GHC 7.2.1, Ben just uploaded the Data Parallel Haskell packages (version 0.5) to Hackage. This version is still largely a technology preview and not a production-ready system. Nevertheless, it is significantly more robust than previous versions, especially for programs with a statically fixed depth of nesting of parallelism. For further information on how to install and use Data Parallel Haskell (DPH), see the DPH documentation.
Ben simultaneously released the companion library Repa (version 2.1.1.6) for use with GHC 7.2.1. In contrast to the DPH libraries, which enable nested data parallelism, Repa implements parallel, shape-polymorphic, regular multi-dimensional arrays. See this previous post for some more details.
