 Hi,
 I've run dph-spectral-quicksort 3000000 +RTS -N6 of dph-examples-0.7.0.5
 but it doesn't seem to use all the 6 hyperthreads. You can see the system
 monitor attached.
 Same goes for the other quickhull-vector example.

 ghc --version
 The Glorious Glasgow Haskell Compilation System, version 7.6.3

 llvm-config-3.0 --version
 3.0

 What am I possibly doing wrong?
