That's decent, if it could be achieved. > The paper reports a 22% speed-up from prefetching to avoid write misses. > If I remember rightly, we also got some decent speed-ups from > optimisations aimed at improving the cache behaviour, although this > wasn't using the GHC code generator, so the results aren't directly > comparable. So... was there a reason the GHC work of this research wasn't merged into the GHC distribution? I understood the report to say that the GHC compiler was indeed modified to implement the simple prefetching. -- ### SER ### Deutsch|Esperanto|Francaise|Linux|XML|Java|Ruby|Aikido ### http://www.germane-software.com/~ser jabber.com:ser ICQ:83578737 ### GPG: http://www.germane-software.com/~ser/Security/ser_public.gpg _______________________________________________ Haskell mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell
