Identify Dual Core CPU

Premgy Varghese — Fri, 30 May 2008 09:15:28 GMT

I have different types of HP-UX PA-RISC systems except Superdome.
Can some please help me with commands to identify if my systems got dual core cpu or not?
Basically I need to know the number of detachable physcal CPU units.

Thanks
Premgy

I forgot to mention that my OS is HP-UX 11.11, hence machinfo won't work for me.

ioscan and top displays the number of cores. Nowhere is counts physical units.

is there any options with cstm ?

Thanks

Is this your thread?

AFAIK each system can have either single core or dual CPUs, or better a particular system model only supports single or dual cores.

I'm not aware of a certain model that can have either single or dual cores.

Hmm, difficult to say ...

The PA8800 and PA8900 CPUs are always dual cores (sometimes with one core deactivated), so if you have a system with these CPUs - you have always dual cores.

But a system that supports these CPUs can *never* have an older single core CPU and vice versa.

To keep it simple, if you know the exact system model, you already know if it has dual cores (this applies to PA-RISC only).

I'll give you an example:

The rp7400 (n-class) can have either pa8500, pa8600 or pa8700 cpus - always single core (same for L-class)

the rp7420 can have either pa8800 or pa8900 - always dual cores.

That's perfect answer for me. Thank you very much
