Oh, I guess this got lost in the discussion, but I don't really care how
parallelism is implemented. Process, level ala parallel make would be
fine for me. I just want to make sure that MLton can use that extra
core for something!
I'll have to say I was a little skeptical about this whole multi-core
thing, but then I started noticing all these Pentium Ds floating around.
A dual core Pentuim D running at 2.6hz per core is around $268. Shipping
systems are below $1500. AMD seems to be aiming their dual cores at the
higher end server market. Intel is playing catchup and I think is
attacking the low end. If you look at the roadmaps for both Intel and
AMD they are in a pissing match to figure out who can deliver the quad
core chip! Remember all the real profits are in the server market. Us
desktop users litteraly get the server chips that can't run fast and
cool enough! BTW you would be quite surprizsed about how all the thermal
and performance concrens of a laptop chip and a server chip are more
alike than different. I expect to see an Apple branded x86 with a dual
core pentium M in a little more than a year. :)
In less than five years, everything, execpt for the very low end, I
suspect will be multicore. Languages that have some sort of seperate
compilation mechanisms can take advantage of the extra cycles. I'm
concerned that the whole program methodology while quite elgeant and
practical today, will look less and less so in the future.
