Control.Parallel.Eden.MapReduce
Description
This Haskell module defines map-reduce skeletons for the parallel functional language Eden.
Depends on GHC. Using standard GHC, you will get a threaded simulation of Eden. Use the forked GHC-Eden compiler from http://www.mathematik.uni-marburg.de/~eden for a parallel build.
Eden Group ( http://www.mathematik.uni-marburg.de/~eden ) Depends on the Eden Compiler.

Simple map-reduce skeletons
parMapRedr :: (Trans a, Trans b) => (b -> b -> b) -> b -> (a -> b) -> [a] -> bSource
Basic parMapRedr skeleton - as many processes as noPe. local pre-folding per PE and final folding of PE-results via different fold variants
parMapRedl :: (Trans a, Trans b) => (b -> b -> b) -> b -> (a -> b) -> [a] -> bSource
Basic parMapRedl skeleton - as many processes as noPe. local pre-folding per PE and final folding of PE-results via different fold variants
parMapRedl' :: (Trans a, Trans b) => (b -> b -> b) -> b -> (a -> b) -> [a] -> bSource
Basic parMapRedl' skeleton - as many processes as noPe. local pre-folding per PE and final folding of PE-results via different fold variants
offline map-reduce skeletons
offlineParMapRedr :: (Trans a, Trans b) => (b -> b -> b) -> b -> (a -> b) -> [a] -> bSource
Offline parMapRedr skeleton - as many processes as noPe. local pre-folding per PE and final folding of PE-results via different fold variants, BUT local selection of input sub-list by worker processes
