Hi,

I am trying to compile and run my program so that it utilises more than one core on my machine. I have looked at http://haskell.org/haskellwiki/Shootout/Parallel/BinaryTrees and am using parMap at a point in my code.

I compile with

ghc --make -O2 -threaded

and run with the options

+RTS -N5

The runtime complains that it doesn't understand the N option.

I am running 6.10.4 on Windows XP.

Cheers

Mark
