VMS has done this for years. I believe that OS/MP did that as well, but don't have a MP machine running it to try that out. The logic behind it, as it was explained to me, was that the units is in "% of A CPU in use" so when you have 2 CPUs busy all the time, it reports that you are using 200% of A cpu, or 2.00 CPUs. In a uniprocessor system, you'd be using 100% of A cpu, or 1.00 CPUs.
