I recently read the paper on upcoming generalized stream fusion in vector and DPH libraries. It seems to be very interesting development. I am now starting to experiment with DPH (starting with GHC...

I'm trying to do some simple experiements with Data Parallel Haskell running, but I clearly have some options wrong. even when I try something very simple like sumP [:1.0,2.0:] I get an excepti...

I was trying to implement the nqueens problem using DPH but I ended up with the Can't vectorise GHC.Prim.Int# error. When I googled for the error I found a GHC Bug which talks about vectorizing lit...

I've been doing a lot of research into Data Parallel Haskell, and found two seperate parallel array types. The [::] type seems to show up more in the research papers and seems to be the ideal type,...

To be more specific, I have the following innocuous-looking little Repa 3 program: {-# LANGUAGE QuasiQuotes #-} import Prelude hiding (map, zipWith) import System.Environment (getArgs) import Dat...

I'm using GHC 7.4.1 to try to compile a program that uses Repa. But partway through compilation, I'm running out of memory. With ghc -v, I can see that it's getting stuck in the SpecConstr phase. ...
