    2525 * External core (output only) now works again

    27  * Data Parallel Haskell (DPH), which supercedes NDP) is now an extralib
     27 * '''Data Parallel Haskell''' (DPH) comes as part of GHC.  In 6.10, for the first time, DPH includes a full vectoriser, so the system is much more usable than before.  It's still really an alpha release though; we very much welcome friendly guinea pigs, but it's not ready for your 3 gigabyte genome search program.  We have a lot of performance tuning to do.  We've written a new paper [http://research.microsoft.com/%7Esimonpj/papers/ndp/index.htm Harnessing the multicores: nested data parallelism in Haskell] (FSTTCS'08), which gives a tutorial overview of the system, focusing especially on vectorisation.
