Hi. I have a function that do some IO (take a file path, read the file, parse, and return some data), and I would like to parallelize it, so that multiple files can be parsed in parallel. I would like to use the simple mapReduce function, from Real Word Haskell: mapReduce :: Strategy b -- evaluation strategy for mapping -> (a -> b) -- map function -> Strategy c -- evaluation strategy for reduction -> ([b] -> c) -- reduce function -> [a] -- list to map over -> c mapReduce mapStrat mapFunc reduceStrat reduceFunc input = mapResult `pseq` reduceResult where mapResult = parMap mapStrat mapFunc input reduceResult = reduceFunc mapResult `using` reduceStrat Is this possible? Thanks Manlio Perillo I
