Comment(by parcs):

 As of GHC 6.12.1, you can omit the number of processors and pass in `-N`
 by itself and GHC will automatically determine the number of processors to
 use. And as of GHC 7.6.1, you can also adjust the number of processors at
 runtime via `GHC.Conc.getNumProcessors` and `GHC.Conc.setNumCapabilities`.
