how to get cpu speed and cpu L2 cache size via API

[alert0919]

i would like to get PA-RISC and Itanium CPU Speed and L2 cache
I would like to use API to solve it via pstat
could some one give me a C program to do that
My OS include 11v1 11v2 11v3

or tell me how to use pstat to do that
because I use command:machinfo only support Itanium 11.23 Above,but it display type are different 11.23 and 11.31,so I would like to use pstat API to do that

could someone help me?
thanks

Hi,

Try using the system call sysconf();

do a man on sysconf. You should be able find all the properties w.r.t the CPU.

_SC_CLOCKS_PER_SEC
_SC_CLK_TCK


or try using pstat_getproc().

there is a structure which has all the properties
pst_processor.

also don't forget to check the man for pstat_getproc

Hi,

Check below link regarding pstat as follows,
http://docs.hp.com/en/B9106-90009/pstat.2.html
http://docs.hp.com/en/B9073-90040/apbs01.html

You can check by taking nickel output

#cd /opt/contrib/bin
#./nickel

if you wanted a command through which you can extract use:

/opt/sfm/bin/CIMUtil -e root/cimv2 HP_Processor

this will list in the form :

or you can as well use

confstr

Hi,

For HPUX 11iv1 11.11, you should have the latest OE which was released in December 2006.

You can try looking into pstat_ calls.

Thanks

Sorry, that's wrong. The latest _Support Plus_ (standard patch bundle) is June 2009, but the last/latest Operating Environment (OE) Update Release for 11.11 is in fact December 2006. Shivaprasad was correct.

Regards!
