Someone asked about whether anyone was working on 
parallel implementations of Haskell.

Good news: we are; we have a parallel implementation running on the
GRIP multiprocessor, with absolute wall-clock speedup over the same
programs running on a comparable uniprocessor (never to be taken 
for granted!).  This has only recently sprung to life, so it will be
a while before we can report proper results.

Bad news: it only runs on GRIP at present, so that rather limits its
distribution.  We have access to a Meiko transputer machine, but it
is quite a lot harder to deal with a distributed memory architecture.  The
compiler would port rather easily to a shared-memory multiprocessor,
but we don't have access to one at present.
