Parallel GHC on Altix?

[Chad Scherrer]

Hi,

I'd like to get more involved in parallel programming in Haskell, and I have
access to an SGI Altix machine (a shared-memory multiprocessor). Can someone
tell me, if I download a 64-bit GHC 6.5 snapshot, to what extent will
parallelism "just work"? Specifically, I'm interested in
* parallel evaluation strategies
* nested data parallelism
* forkIO, MVar's, and STM

My understanding is that for the 32-bit version, this all works in parallel,
but GC is sequential. Is that still the case? Is the 64-bit version in the
same state?

Finally, is there an estimated date for when 6.6 will be available? I'm
happy to experiment with snapshots, but most admins around here are much
more comfortable installing an official release of some sort.

Thanks!
