Hello Joel,

my sentence should be read as "is it true...?" - i had lost a track whether it was incorporated in GHC or not. the idea is that GHC should be extended to be able to write out dependencies list built in the --make mode. Then rather simple scripts may be used to distribute the work among many cores/boxes
who can enlighten me about presence/absence of multi-core GHC support?
GHC itself doesn't support multithreaded --make compilation. I have some old patches to do this, which I used for the measurements in the Haskell Workshop 2005 paper, but it was never completely robust. This is one reason I wrote the 'setup makefile' patch for Cabal[1] recently. With that patch you can get parallel compilation on a multiprocessor using 'make -j' when using Cabal. (I know that not everyone has make, it isn't intended to be a portable solution - the ultimate goal is to use Cabal in GHC's build system, where you need make anyway).
