Multi-cpu Erlang is a very attractive proposition.

I bought a Dell Dimension 8400 sold as a single-CPU machine and replaced
the M$ OS with Linux.  SuSE Linux automatically installed a
multi-processor kernel, and I see the two CPUs running concurrently in
xosview.  However the total load is never greater than 1.  I am probably
blocked by a single-CPU ATI proprietary graphics driver, and maybe other
single-CPU stuff.  However these road blocks will no doubt be removed and
multi-CPU Erlang will then become very attractive.
