IIRC the latest Mac Pro system use Xeon processors that are HT
(hyper-threading, aka SMT) capable, each core is capable of running
two threads concurrently. This gives you 16 "logical" cores even
though you only have 8 physical cores.
Try the following...
[0:512] > sysctl hw.physicalcpu hw.logicalcpu
hw.physicalcpu: 8
hw.logicalcpu: 8
This seems to be it. Interesting. I get:
darwin:~ bhaller $ sysctl hw.physicalcpu hw.logicalcpu
hw.physicalcpu: 8
hw.logicalcpu: 16
New to me. :-> Thanks!
