How can verify if my processor is mono-processor or bi-processor?

[alessandro_37]

Dear all

I have understood that information about Processor type is extracted by
(Thanks Sundar):

# model
9000/800/XXX
# grep XXX /usr/sam/lib/mo/sched.models

In my system HP-UX 11.0:
#model
9000/800/L1000-44 (what does means L1000-44? Is the Porcessor model?)
#grep L1000-44 /usr/sam/lib/mo/sched.models
L1000-44 2.0 PA8500 (this means that i have an PA-RRISK 8500 version 2.0.
Is my consideration correct ?)

and most important, how can I verify if the processor is mono or bi-processor??

Thanks in advance
Alex





How can verify if it is mono or bi-processor?

Hello Alex,

If I understand you correctly, then just run something like this:

top -s 1

At the top you will see a line for each processor, depending on how many you have.

Hope this helps!

... or run

ioscan

you will see an entry for each processor.

Alex,

If, by "mono or bi-processor", you're referring to the number of processors, simply do "ioscan -k |grep processor |wc -l".

Hi, thanks for your quickly reply,
but i need to know if my processor (i have only one processor installed on my system) is mono or bi-processor.

Hope this is clear.

Another way is if you have Online Diags on you can use xstm (x motif) cstm (command version) mstm (asci type gui).

I usually use cstm. I know you can pass what your looking through a pipe on the command line. But to interactively look just do
type cstm
map
which will show you how many cpus you have. And if you want more details on it you can do
sel dev xx (The number of the processor)
info
infolog

This is an L Class system ( or rp5400 ), and has 440MHz processor(s) - all the commands mentioned would see a dual core cpu as two seperate cpus - so you have only a single, single-core cpu. (dual core cpus were introduced only at the start of this year, whilst I would hazard that the system you have is about 4-5 years old)

Well, then, I can only guess now that you're referring to the recently announced dual core processors? Yours is not a dual core, I can assure you.

Thanks Pete,

wich is the command to verify it?
Thanks in advance

Alex,

The model command that you mention in your question is your clue. It's telling you that you've got 440MHz PA8500 processors. The new dual-core processors are PA8800 processors.

All,
thanks a lot for your help.

Now is clear.

I have an PA-RISK PA8500 440 MHh and it is
mono-processor
(or as you prefer: an single-core cpu)

Greetings to all

Alessandro,

Your question would have be immediatly understood if you use "core" rather the processor, i.e. dual core processor

Nicolas,
thanks for your suggestion :-)
