Hey Michael, how about putting the multi-threaded tests into a suite of their own to show the speed difference with x number of cores?

All of the compilation tests are able to handle multiple jobs concurrently and is done automatically... In regards to making an SMP suite, that may be a good idea. There is also the multi-thread friendly ET:QW and Quake 4 and a few others.Michael Larabel

I'd be interested to see if "true" quad-cores such as the Phenom have an edge over multi-chip processors such as the Core 2 Duos/Quads as far as scalability goes (i.e., how much performance is gained from using one core to using all cores). It'd be nice if the "multicore" tests ran with only one core, then two, etc... Performance gain ratios could then be computed (i.e. 1.97x with two cores, 3.72x with four cores, etc).
Obviously, scalability relies primarily on the app itself, but at least we could compare ratios between CPUs.
