Hi, I tried the first example from "A tutorial on Parallel and Concurrent programming in Haskell" but I cant seem to get sparks to get converted to OS threads.
Below is the program I am using. I did ghc --make -threaded program.hs then ./program +RTS -N2 I don't see any speed gain compared to N1. Am I missing something?
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.
