machinfo output interpretation on rx4640

[Modris Bremze]

Hi. I am slightly confused about correct output interpretation from machinfo on a couple of rx4640 servers. Both are ia64 and HP-UX 11.23.

1. On the first server machinfo shows:

Number of CPUs = 4
Clock speed = 1600 MHz
processor family: 32 Intel(R) Itanium 2 9000 series
processor model: 0 Intel(R) Itanium 2 9000 series

According to http://docs.hp.com/en/T2767-90180/ch10s03.html#itaniumtable and http://en.wikipedia.org/wiki/IA-64#Released_processors , these are Itanium 2 Montecito dual-core CPUs. And, considering that (as far as I know) machinfo on 11.23 shows cores, we have 2 physical dual-core CPUs on this server and we have space on the board for two more physical CPUs. Is that correct?

2. Machinfo on the second server shows:

Number of CPUs = 4
Clock speed = 1100 MHz
processor family: 31 Intel(R) Itanium 2 Family Processors
processor model: 1 Intel(R) Itanium 2 processor

According to the same sources as above and rx4640 specs, these are Itanium 2 Hondo dual-processor modules (essentially single core, but having two dies per device). Taking into account the same consideration about machinfo output on 11.23 as before, is it correct to conclude, that this server also has space left for two more processor modules?

Hi,

if you doubt about the physicall number of processors in your system, you can always have a look at the 'DF' output on the command shell of the MP in your system.

Remember there is also the Hyperthreading setting, not sure about the support on UX for it.



- log into the MP via telnet
- go to the command shell using the CM
command
- run the DF command, specify S and see how
many procesors are listed.


The below examples is from a RX4640 with 2 Hondo's and the second is from a RX4640 with 4 Montecito's.

This does not answer your MACHINFO question but you could use the above to find the answer of what is installed in your server.

"machinfo" in 11.23 is counting cores, in 11.31 it is counting modules (with cores per socket), e.g.

11.23:
6 CPUs in a cell (must be cores)
...
processor 0 3/120 processor CLAIMED PROCESSOR Processor
processor 1 3/121 processor CLAIMED PROCESSOR Processor
processor 2 3/122 processor CLAIMED PROCESSOR Processor
processor 3 3/123 processor CLAIMED PROCESSOR Processor
processor 4 3/124 processor CLAIMED PROCESSOR Processor
processor 5 3/125 processor CLAIMED PROCESSOR Processor
...

/usr/contrib/bin/machinfo
CPU info:
Number of CPUs = 6
Clock speed = 1100 MHz
Bus speed = 400 MT/s
CPUID registers
vendor information = "GenuineIntel"
processor serial number = 0x0000000000000000
processor version info = 0x000000001f010504
architecture revision: 0
processor family: 31 Intel(R) Itanium 2 Family Processors
processor model: 1 Intel(R) Itanium 2 processor
processor revision: 5 Stepping B1


...




11.31:

/usr/contrib/bin/machinfo
CPU info:
1 Intel(R) Itanium 2 9000 series processor (1.59 GHz, 18 MB)
532 MT/s bus, CPU version C2
2 logical processors (2 per socket)

[Modris Bremze]

Thanks for the replies. Physical access right now is a bit of an issue, so machinfo seems to be the only way. Torstens answer seems to confirm my findings.

[Torsten. · Accepted solution]

Finally you should have space for 2 more modules in both servers.

[Sameer_Nirmal]

For HP-UX 11.23 there is a patch PHCO_37801 which provides information about number of sockets and cores per socket for multi-core processors.

[Torsten.]

Nice new feature, from the patch database:

The machinfo command is enhanced to provide the following
information:

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

[Modris Bremze]

Right, thanks. I'll check out the pach for future occasions.
