[Chanthu]

Hello,

Anybody having a c/c++ program which will return the above cpu information on HP itanium?

Thanks and regards,
Chanthu

You can get CPU info from pstat_getprocessor(2), example 2:

Hi Dennis,

Thanks..

This will give total cpu count.
Is there any way to find out logical processors(cores) count and thread count on HP itanium 64. On x86 machines cpuid() will give the information. similarly any functionality available for HP itanium ?

CPU == core.
Have you looked at struct pst_processor to see if there are any details about the type of processor?
You should be looking at the 11.31 Release Notes if you want to see about hyperthreading.

You already have your identifier:

processor family: 32 Intel(R) Itanium 2 9000 series
processor model: 0 Intel(R) Itanium 2 9000 series
processor revision: 7 Stepping C2


Itanium 2 9000 series = dual core Montecito

Hi Chantu,

You can check it by entering shell
shell means EFISHELL which comes after reboot the server & enter the EFI shell
shell>info all;


or from run the nickel script

#./nickel

Hello Chanthu

I also have same question.

Do you slove this problem?

if then, plesae let me know it.

Really I want know

1. Number of physical processor
2. Number of logical processor( number of cores)

Thank you

@Henry:
Consider to open your own thread!

"machinfo" in 11.23 reports the number of cores, in 11.31 it reports the number of modules and cores per CPU. HT is only possible in 11.31; check with "setboot".
