I read somewhere that GHC's SMP support has been "tested up to 40 cores".
Pray tell me, what the heck kind of machine has 40 cores? (And where can I buy mine from?? :-D LOL!)
40 cpus.
It's a midrange Sun Fire server, something like this one

You'll need more than spare change to get started though.
o_O *dies* ...which gets the question "where did *you* get one?!"
*However* 8 core amd64 machines are practically commodity boxes now. Go get one.
I'm currently sitting here typing on a 2-core AMD64 box. ;-) However, it seems socket-939 is history now, so... Besides, all the benchmarks seem to say Intel's Core 2 Duo is the faster product. Currently. But then, if I could figure out how to use my GPU... Not fantastically relevant, but... the makers of the Persistence of Vision Ray Tracer are currently working on a new multi-threaded beta. It's taken them *months*. AFAIK, it's written in C, and they had to spend forever removing global variables and whatnot. Huge internal restructuring to make it work properly. I almost want to sit down and code something in Haskell and see how many times slower it is... ;-) [The issue with that being 1. I can't figure out a really good set of abstractions, and 2. the type system hates me. Oh, and 3. it would have to save files in PPM format, because I can't figure out how to do bitmapped graphics or PNG writing in Haskell...]
