Sorry, not at the moment. We implemented a hacky version of it for our Haskell Workshop '05 paper: http://haskell.org/~simonmar/bib/multiproc05_abstract.html but later concluded that GHC really needed some more substantial re-engineering to make it reliable. There's a ticket for it: http://hackage.haskell.org/trac/ghc/ticket/910 Cheers, Simon

We're also going to try and solve this in Cabal by having Cabal do the module dependency analysis and then call ghc (and pre-processors) in single shot mode and in parallel. Duncan
