I am currently experimenting with parallelizing C-programs. I have therefore written a matrix vector multiplication example that needs 13 seconds to run (5 seconds with OpenMP). Because I like Haskell I did the same in this language, but it takes about 134 seconds. Why is it so slow? Does someone have an idea?
reading "An approach to fast arrays in Haskell" http://www.cse.unsw.edu.au/~chak/papers/afp-arrays.ps.gz might be a good idea for everyone wondering about ghc performance -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
