Is my server multicore?

[Tom Kunkel]

Without pulling the box out and peering inside, is there a way of telling if the server has single core or multicore processors?

[A. Clay Stephenson]

Of course, use "The Force". Otherwise, know enough about your equipment model to be able to look the information up or to run diagnostics and information utilities to ask the box itself. When you ask a question like this and provide no details, it becomes very difficult to answer.

haha.

Details then: I have a rp4440 that reports 4 CPUS (cstm, glance, sar, etc). There is a rp3440, a rp5470, etc

What I need to know is, without physically opening the box, if it is 2 physical CPUs or 4.

Any ideas?

Oh yes, HPUX 11i

Hi,

with 'top' you should see it.
But it can be dual-core, so maybe one cpu with two cores shows two cpu stats.

Hello,

ioscan -k | grep -n processor | wc -l

should do the trick.

[Tom Kunkel]

Nope. Top, ioscan, glance, sar, cstm all show the same number of 4 processors. I have jsut had it confirmed that it is a 2-way dual core job. But how can I tell the difference from the operating system?

Hi Tom,

I don't think there is direct command to display the number of dual cores inside a server. The only two dual core PA-RISC processors are the PA-8800 and the PA-8900.

# echo "selclass qualifier cpu;infolog" | /usr/sbin/cstm | grep "CPU Module"

If above command displays one of the two cpu mentioned above, you know you have a dual core.

Best regards,
Robert-Jan

Brilliant! That's it. One server has 8700's and true enough, is isn't multicore.

Thanks. This was really helpful.
