CPU Core count - one, two, three, four... wait is it dual core or hyperthreading...

[Raakin]

So... has anyone come up with a good way (simpler the better) to determine the CPU core count of their organization?

I do not know if you are like me but my AIX/Linux/Windows Admins may have access to the CPU core count but it usually takes them awhile to get that information back to me. Though I do have access to a good chunk of the servers I am less familiar with the AIX and Linux side of things.

I have been trying to device some scripts that calculate the CPU core count easily.

For AIX/Linux I was thinking of scripting and greping the output of /proc/cpuinfo.

Any sound/proven ways?

Sorry I do not see a script on that page to help a TSM Admin find the CPU Cores on a given server.

I am painfully aware of the conversion core to PVU conversion. Thanks for posting though.

ohhh, you were looking for a script, sorry - I must have skipped over that part.

In all fairness, I debated between this License forum and Scripting.

ok cwilloug needs more coffee today ;-)

does not a "query systeminfo" or "show config" shows you more informations about your system? I do not have to possibility to look for, but as far as I remember it will show you more details about your cpu? Or I'm wrong?

Never done this.. but this can help you... Since i'm doing all the BA installation for my windows server, i'v add it in my ba client intallation script.

- for windows create a vbscript that query the WMI CPU class. microsoft technet script center can give have the complet vbs for querying de CPU WMI classe. redirect this to a txt file.

- add it in the pre or post command on the backups schedule.

- grab the file and leave!

WMI will give you some information not all of it

This is a WMI query code of the Win32_Processor WMI class in vbscript.

you just have to play with it!

"query systeminfo" does show a lot more info about the system, but oddly enough, not the cpu core count.

As far as "show config" I do not see where to use that command; is it a OS command or Tivoli?

AIX:

lsattr -El sys0 |grep ent_cap |awk {'print $2'}

(upper e lower L, some people think it is an upper i or the number 1)

This will show the number of CPU cores that are allocated to the server. If it is a full LPAR, it will show how many are in the server and if it is a partial LPAR, it will show how many are allocated to it in the HMC.

I think working with /proc/cpuinfo makes the most sense on Linux. I don't have a window open to a Linux box right now or I'd give you the syntax for it as well.
