Identification of number of cores of CPUs

Amir Pakdel — Sun, 02 May 2010 10:15:08 GMT

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.

Current Product Number : A6961A
Original Product Number : N/A

System Serial Number: : DEH4419103

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

/usr/contrib/bin/machinfo

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

This is the Montecito, a dual-core CPU.

Re: Identification of number of cores of CPUs

Torsten. — Sun, 02 May 2010 12:11:52 GMT

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

Re: Identification of number of cores of CPUs

Amir Pakdel — Sun, 02 May 2010 16:30:48 GMT

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.

Re: Identification of number of cores of CPUs

Torsten. — Mon, 03 May 2010 02:47:08 GMT

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?

Re: Identification of number of cores of CPUs

Amir Pakdel — Mon, 03 May 2010 02:59:38 GMT

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 — Mon, 03 May 2010 03:09:50 GMT

>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.

>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.

Re: Identification of number of cores of CPUs

Leonard C. — Mon, 03 May 2010 03:18:25 GMT

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

Hi,

# machinfo
CPU info:
Number of CPUs = 8
Clock speed = 1600 MHz
Bus speed = 400 MT/s

From Machinfo ,i saw number of cpu 8 .In rx4640 server there are 4 cpu socket so 4 dual cpu are installed .

Check below link ,

Re: Identification of number of cores of CPUs

Torsten. — Mon, 03 May 2010 03:56:13 GMT

and again machinfo:

# machinfo
CPU info:
1 Intel(R) Itanium 2 9000 series processor (1.4 GHz, 12 MB)
399 MT/s bus, CPU version C2
2 logical processors (2 per socket)
...

The "2 per socket" is what you want to know?

The output I have got from machinfo does not contain that "2 per socket". Please take look at the output of machinfo above.

This is a single core, the Itanium 2 (codename Madison).

Hi Amir,

The defect description part of the patchnotes of the patch, torsten, points to, not only mentions that single core cpus will not display "core lines" in the machinfo output,

QUOTE http://www13.itrc.hp.com/service/patch/patchDetail.do?admit=109447627+1273084557679+28353475&patchid=PHCO_40685&sel={hpux%3A11.23%2C}&BC=main|search|

Patch Name: PHCO_40685

Patch Description: s700_800 11.23 Cumulative machinfo command patch

[..]
Defect Description:
[..]
# machinfo
CPU info:
Number of CPUs = 4
Number of enabled CPUs = 4
Number of enabled sockets = 2
Cores per socket = 2
...

The additional lines pertaining to processor sockets will
appear only on systems with multi-core processors. Systems
with single core processors will only present the number of
CPUs and the number of enabled CPUs.

UNQUOTE http://www13.itrc.hp.com/service/patch/patchDetail.do?admit=109447627+1273084557679+28353475&patchid=PHCO_40685&sel={hpux%3A11.23%2C}&BC=main|search|

, but also that this patch is part of a set of "socket information patches".

QUOTE [PHCO_40685]
[..]
The following patches will be required for machinfo to
provide socket information:

PHKL_37803
PHKL_37804
PHKL_37805
UNQUOTE [PHCO_40685]

And the above list of patches, is apparantly not "exhaustive", as clicking one of the additionial patches, f.e. PHKL_37803, will point to yet a 5th patch, PHKL_37806, patch to be installed..

Anyway, throwing the patch PHCO_40685 patch through a patch dependency analyzer will show the following dependency patches, that would be advised to also get installed, together with PHCO_40685, if not allready installed..

There is lots of way to examine what you are looking for as stated here. Additionally ,you can use (if you have GSP AND nPartition) remote console to see all hard partitions on same terminal;
