cpu query

Shah Gaurang B. — Sat, 08 Sep 2007 06:23:20 GMT

Hi Friends,

Is there a way to query from the OS whether the system is using single or dual core cpu's for PA-RISC of Itanium.

Regards

Hi,

Try,

# /usr/contrib/bin/machinfo
CPU info:
2 Intel(R) Itanium 2 9000 series processors (1.59 GHz, 18 MB)
532 MT/s bus, CPU version C2
--> 4 logical processors (2 per socket)
Regards,
Robert-Jan

and the info from a PA-Risc system

# /usr/contrib/bin/machinfo
CPU info:
1 PA-RISC 8800 processor (800 MHz, 64 MB)
CPU version 5
---> 2 logical processors (2 per socket)

The type of the CPUs is

processor family: 32 Intel(R) Itanium 2 9000 series

aka Montecito. This is a dual core CPU.
(according to this it must be dual core too, because of 18MB L3 cache):

Dual-core 1.6 GHz with 18 MB L3 cache
