[Beowulf] Any ideas how Intel compilers detect CPU model?

[Christopher Samuel]

Hey folks,

I'm helping another group bring up a system that involves virtualisation
and whilst they are Haswell CPUs it appears that the version of
qemu/libvirt that is used makes /proc/cpuinfo list cores as Sandybridge
(in the text at least).

Does anyone know how the Intel compilers detect architecture?  Do they
look at the model/stepping info or do they do some other tricks?

All the best!
Chris
