Thanks. There is indeed no package information (hw.packages), that's why
hwloc does not include any socket object.

Can you send your lstopo output?
preferably with latest trunk tarball

One way to solve this problem (which may also occur on old Linux
distribs) would be to store the CPU model in the machine object. But
we'll have to
Hello,
Robin Scher indicated how to get the info on a Mac.
At least on mine (OSX 10.4) with darwin 8.11.1
where
$ sysctl -a machdep.cpu.brand_string
machdep.cpu.brand_string: Intel(R) Core(TM)2 CPU T7400 @
2.16GHz
I unfortunately have no socket:

Oh, this is indeed *exactly* the model name string. I only knew about
the vendor_id string.
