Re: [Haskell-cafe] Newbie question about tuples

Donald:

Yeah, there's some known low level issues in the code generator regarding heap and stack checks inside loops, and the use of registers on x86.

But note this updated paper, http://www.cse.unsw.edu.au/~chak/papers/CLPKM07.html

Add another core to your machine and it is no longer 4x slower :) Add 15 more cores and its really no longer 4x slower :

Maybe this is yet another newbie stupid question, but do you mean that GHC does automatic multi-threading? (Haskell seems very suitable for that) Otherwise adding an extra core does not really help does it?
