so it appears cpu0 & cpu2 are the same physical CPU, as are 1 & 3, at least in

Yes it is the same in Windows 2000 and Windows XP as well.

CPU 2 is the virtual processor of 0, and CPU 3 is the virtual processor of 1.

Now I wonder how it works if you have a dual CPU machine with
dual-core processors and hyperthreading?

I'm guessing the CPU 0, 1, 2, 3 would be the physical processors and
4,5,6,7 would be the virtual ones but are the two cores on the same
processor 0 and 1 or is it 0 and 2?

my head spins. me thinks it would be VERY nice if you could just tell prime95 how many instances to run on a multiprocessor, and it defaults to running them on the 'best' virtual processors... having to configure two copies of the program (or two shortcuts with -A1 or whatever), ugh. especially nasty and confusing with system services.
