On my hyper-threaded CPU, your original code works fine. With -N2, I see 100% CPU. With N1, only 50%. I am also using GHC [3]6.8.2. Justin
Hmm, that's curious. I compile with "ghc --make -threaded partest.hs -o par.exe", and then run it with "par.exe +RTS -N2 -RTS". Am I making some silly configuration error? Are you running this on windows?
I think its always worth using -O or -O2 too, for what its worth. -- Don
