Hmm, using parSumFibEuler instead of sumFibEuler, I get > 100% CPU usage (close to 200% if I adjust parameters so both computations take approximately the same time). Works for me, then. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
