Hi all, How do we find the number of physiscal processors in a linux
system. To be very specific I am NOT talking about the logical
processors.

For example dual-xeon with HT enabled:

# egrep '(^processor|^physical id)' /proc/cpuinfo
processor : 0
physical id : 6
processor : 1
physical id : 0
processor : 2
physical id : 0
processor : 3
physical id : 6

you see four processor's but only two physical id's.

regards
