I&#39;m using the Control.Parallel package on ghc version 6.10.4 and I don&#39;t seem to be getting any parallel threads or sparks created at all with the &quot;-threaded&quot; compilation option using runtime flags &quot;+RTS -N2&quot;.  I&#39;m using simple examples from the paper &quot;A Tutorial on Parallel and Concurrent Programming in Haskell&quot; by Jones and Singh.  <div>
<br></div><div>I&#39;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 &quot;supported&quot; runtime pkg for OS X from the ghc website.</div>
