yes but this command give me information about number cores, but I need information about physical cpus modules, I know that my server have 4 physical, but how can i check it form OS?

Thanks

Please check if you have "machinfo" command that would help you to get information of you system and CPU is included in this output.

#machinfo
CPU info:
Number of CPUs = 8
Clock speed = 1598 MHz
Bus speed = 533 MT/s

If system is running 11.31 it looks like this:

# /usr/contrib/bin/machinfo
CPU info:
32 Intel(R) Itanium 2 9000 series processors (1.6 GHz, 18 MB)
533 MT/s bus, CPU version C2
64 logical processors (2 per socket)


(Note: 2 per socket!)

I have from cpuconfig information

Cab/
Cell
Slot/ # of L3 L4 Family/
CPU Logical Cache Cache Model Processor
Cell Module CPUs Speed Size Size (hex.) Rev State
---- ------ ------- -------- ------ ------ ------- --- -------------
1 0/1/0 4 1.6 GHz 9 MB None 20/01 A1 Active
1 0/1/1 4 1.6 GHz 9 MB None 20/01 A1 Active
1 0/1/2 4 1.6 GHz 9 MB None 20/01 A1 Active
1 0/1/3 4 1.6 GHz 9 MB None 20/01 A1 Active



and machinfo give me info

bash-3.2# machinfo
CPU info:
4 Intel(R) Itanium 2 9100 series processors (1.6 GHz, 18 MB)
533 MT/s bus, CPU version A1

I know that I must divide number logical cpu in two core, (two per socket) but it is posible find this information as number , because this information isnot obvious.Thanks for information

My another question why cpuconfig show

4 logical module for all cpu

Cab/
Cell
Slot/ # of L3 L4 Family/
CPU Logical Cache Cache Model Processor
Cell Module CPUs Speed Size Size (hex.) Rev State
---- ------ ------- -------- ------ ------ ------- --- -------------
1 0/1/0 4 1.6 GHz 9 MB None 20/01 A1 Active
1 0/1/1 4 1.6 GHz 9 MB None 20/01 A1 Active
1 0/1/2 4 1.6 GHz 9 MB None 20/01 A1 Active
1 0/1/3 4 1.6 GHz 9 MB None 20/01 A1 Active

>>4<< Intel(R) Itanium 2 9100 series processors (1.6 GHz, 18 MB)
533 MT/s bus, CPU version A1
8 logical processors (2 per socket)

The number is there (4 processors) - first line.

The Itanium 2 9100 series (aka Montevale) is always a dual core.
