Does 16 processors mean 16 CPU's

>How did you decide that it is 8 core dual CPUs?

google pointed to Intel's web page for:
Itanium 9000 series

Hi

If you will look H/W path of ioscan output

FOR DUAL CORE CPU

processor 0 0/120 processor CLAIMED PROCESSOR Processor
processor 1 0/121 processor CLAIMED PROCESSOR Processor
processor 2 0/122 processor CLAIMED PROCESSOR Processor
processor 3 0/123 processor CLAIMED PROCESSOR Processor

H/W path will be 0/120 than 0/121

AND FOR SINGLE CORE it will be diffrent like

processor 0 37 processor CLAIMED PROCESSOR Processor
processor 1 45 processor CLAIMED PROCESSOR Processor

2. 8700 is Single Core and 8800 Is dual Core

SORRY fOR TYPO ITS 8900 NOT 8800

Hi mjos,

Itanium 2 is a dual core CPU.

So you should have 8 Dual Core CPUs

Another best way to double check is to check hardware specs you used to buy servers.

>Deepakitpro: Itanium 2 is a dual core CPU.

Intel has retconned Itanium 2 away. It is all Itanium now.
Note not all Itanium (2) are dual core, only series 9000 and 9100 are.

[Torsten. · Accepted solution]

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

The
Intel(R) Itanium 2 9000 series aka Montecito
Intel(R) Itanium 2 9100 series aka Montevale


Montecito and Montevale are both dual core CPUs - allways!

The "smallest" server like rx2660 can have even a dual core with 1 core disabled, but anyway - it reamins a dual core.



BTW, in SAM you see 400MHz.

This may be OK if this is a HPVM - if not, you need patches to see 1.6GHz!

All, thanks for your answers. But my basic question still remains unanswered.
I know itanium servers are dual core
What I want to know is that whetere there are 8 dual core CPU's or 16 physcial CPU's.
What is the command that will show us the exact no of CPU's & if it is dual core CPU's then how do we find it out.
One another server top is showing as 54 CPU's. Does that mean this server as 27 dual core CPU's?

Hi mjos

I have given you simple method to identify

If you will look H/W path of ioscan output

FOR DUAL CORE CPU

processor 0 0/120 processor CLAIMED PROCESSOR Processor
processor 1 0/121 processor CLAIMED PROCESSOR Processor
processor 2 0/122 processor CLAIMED PROCESSOR Processor
processor 3 0/123 processor CLAIMED PROCESSOR Processor

H/W path will be 0/120 than 0/121

AND FOR SINGLE CORE it will be diffrent like

processor 0 37 processor CLAIMED PROCESSOR Processor
processor 1 45 processor CLAIMED PROCESSOR Processor
