Re: CPU cores
Few ways to do it.
top shows a CPU per core.
ioscan can be used to grep for CPU's
Best way to go is to actually look at the specifications for your particular system on http://docs.hp.com

Re: CPU cores
# model
and
# machinfo
With Itanium it could be a bit difficult sometimes, because there are single cores, dual cores or 2 single cores in a single slot.
Hope this helps!
Regards
Torsten.

Re: CPU cores
Again,
You want cores, go with ioscan.
You can safely use ioscan -fnk to get a core counts.
You can use awk and/or grep to get a count by then piping to wc -l

You have Montecito processors. Which are dual core. So you have 6 cores, 3 sockets.
