Dual single core hyperthreading xeons if I read the above correctly.
Certainly given the physical id is 0 on two of them, and 3 on two of
them, and there is 4 cpus listing 2 siblings, and all of them show core
id 0, that is how I would understand it. If any showed core id other
than 0, I would assume dual core.
