Identification of number of cores of CPUs

[Amir Pakdel]

I have different types of HP-UX systems. Can someone please help me with identification of number of cores of CPUs?
So far, I have tested the following, and all of them merely listed all of the cores!


# echo "map
> selall
> info
> wait
> infolog" | cstm

Hardware path: system


Sensor Information has to be gathered from the hardware. Please wait. Acquiring
this information should take no longer than five minutes.

Product ID : ia64 hp server rx4640
Current Product Number : A6961A
Original Product Number : N/A
System Firmware Revision : 04.29
BMC Revision : v04.06
System Serial Number: : DEH4419103

System Software ID : 2052534650



For additional information about the system and the CPUs, please run the
following command:

/usr/contrib/bin/machinfo

Additionally, execution of the script found in http://mirrors.develooper.com/hpux/faq.html gives nothing more useful:
# ./ux

Basically I need to know the number of detachable physcal CPU units.

Thanks

This is the Montecito, a dual-core CPU.

[Torsten.]

The rx4640 has 4 slots, you have 8 CPUs, so there are 4 dual core modules.

[Amir Pakdel]

Posted output of commands are just a sample. I would like to have a script or a method to be able to investigate all of our servers.
Even if there is list of number of cores of different models of CPUs, that would be useful.

>I would like to have a script or a method to be able to investigate all of our servers.

For Integrity servers, I would stick with machinfo. Otherwise ioscan would work for both PA and Integrity.

[Torsten.]

If you see these CPU types:

PA8800, PA8900

processor family: 32 Intel(R) Itanium 2 9000 series
processor family: 32 Intel(R) Itanium 2 9100 series

or maybe

processor family: 32 Intel(R) Itanium 2 9300 series


you can be sure it is dual or (last line) even quad core.

With other Itanium CPU it could be a bit more complicated.

Any examples?

[Amir Pakdel]

Therefore, there is no simple way of determining number of detachable physical CPU units. I mean, for example, there is no single script to run that gives us "You have 4 detachable physical CPU units".
Does anyone know where can I find a list of Itanium CPU specifications? I may be able to map processor model to number of cores and produce the output I need from that.

[Dennis Handly]

>detachable physical CPU units".

What do you mean by this? Sockets or cores?

>I may be able to map processor model to number of cores and produce the output I need.

Why? machinfo(1) does that for you.

[Amir Pakdel]

>detachable physical CPU units".

>What do you mean by this? Sockets or cores?
Sockets; I mean the physical thing that I can buy, I can remove from the server.

[Leonard C. · Accepted solution]

You can develop a script such as below method:

- find the ID number of processor family :

Example of possible cases:
processor family: 31 Intel(R) Itanium 2 Family Processors
processor family: 32 Intel(R) Itanium 2 9000 series

Extract the number of core per physical processor as below:
31 => Single core
32 => Dual core
