You could try reading this code (mind the #ifdefs 8o)...

Believe me, it was hard to say too! I should have put more emphasis on
knowing where to look in the massive code base that is condor is helpful...
so based on the code it looks like there's what i would consider a
"bug" between condor's core detection and linux's core reporting
interaction. It seems logical that adding node_id into /proc/cpuinfo
and having condor pick that up would be a simple fix, but as the
thread claims that patch to the kernel was rejected (i'll have to see
why), so it's not available.
Can anyone comment on whether the /proc/cpuinfo routines might ever
get ported to /sys entries instead of /proc which would also alleviate
this (the kernel thread claims is a better interface)?
I'll direct you to Nick (CC'd) on this. He tends to maintain the CPU
