I have run the benchmark routine on a new Intel Core
Duo on a MAC mini. I noticed that it only utilized
one of the cores. In the past I have noticed that it
will utilize all of the CPU's on a machine.

    Yeah, this is a known issue that should be fixed in one of the upcoming
    releases. The issue stems from the code that detects the number of CPUs
    being tied to a PPC section and that instead neads to be bound to something
    more generic (detection of the posix sysctl() call availability).

    Another related issue is that if you disable a CPU with the CHUD tools, the
    ray-trace library doesn't perform the correct accounting. Apple had
    recommended and provided code for a fix for that issue, but it hasn't yet
    been applied and tested sufficiently yet.
