[Openmcl-devel] Speed, compilers and multi-core processors

Here's an interesting thread about the Connection Machine:
I think Paul Krueger's post is on target. Not only do we need a Lisp
that facilitates parallel execution (CM), we need a Lisp that
facilitates a parallel programming paradigm, genetic algorithms,
neural nets, etc.
Since Lisp is the "programmable programing language" and extremely
good for developing embedded languages it is a natural choice.
As Lisp hackers we can go ahead and place orders for those new
BMWs ... :-)
