I'm using the Control.Parallel package on ghc version 6.10.4 and I don't seem to be getting any parallel threads or sparks created at all with the "-threaded" compilation option using runtime flags "+RTS -N2". I'm using simple examples from the paper "A Tutorial on Parallel and Concurrent Programming in Haskell" by Jones and Singh. I'm running on an Intel Mac core 2 duo. Does anyone know how I can check if the parallel functionality in ghc is working on my 6.10.4 ghc package installed on this platform ? I installed it from the "supported" runtime pkg for OS X from the ghc website.
thanks
