As far as I remember some companies ;-) are counting MCMs twice, so actually counting the nodes?A large number of software licensing beancounters in the industry are going to be busy on this one ;-) As long as there is no such notion as 'sockets per node' (which isn't on Linux), everything is fine. It will just report 8 nodes with 6 cores each (in case of a 4 socket M-C). Each core has a associated physical package id, which is just the same for 12 cores or 2 nodes. I have a machine here up and running, so just tell me what sysfs path you are interested in and I can send you the output.Christophe, can you comment on how Linux and/or other bare metal operating systems will be reporting the Magny Cours hierarchy? Until c/s 21118 Xen was just fine, reporting 8 nodes, 4 sockets and 48 cores. It is just this socket per node (which got removed some years ago), which is doing harm. (BTW: I already complained about that last year, when Nitin's patch first appeared on the ML).I'd hope that Xen could follow their lead on this rather than forge new ground, which may result in an incompatible implementation.
