How do i find out on a server whether it is dual core or not.in other words is dual core means 2 cpu's?
Thanks

Hi Navin,

If you have OnlineDiag installed try

# "selclass qualifier cpu;info;wait;il"|cstm

Otherwise you can try

# ioscan -fnCprocessor

or
$ 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

run machinfo

if processor family = 31 then your cpu is dual core cpu.

[Hasan Atasoy]

sorry
processor family = 32 then dual core.

i do not have machinfo in my servers
Thanks

2 per socket always means dual core.


HP9000:

machinfo -v
CPU info:
1 PA-RISC 8800 processor (800 MHz, 32 MB)
CPU version 4
2 logical processors (2 per socket)

Integrity:

machinfo

This is 11.31.
On other releases it looks different.

PA-8800 and PA-8900 are always dual-core, for Integrity the CPU family 9000 and 9100 are always (almost always) dual-core.

Hi:

> i do not have machinfo in my servers

Then you don't ave an Itanium server. Rather, you have a PA-RISC one.

See:

# uname -m

Also post the result of

#model

In the rare case you have a very entry level of a rp34x0 you could have a dual core CPU with a disabled second core.

[Robert-Jan Goossens]

Navim,

Post the model of your server;

# model

James,

If i'm not mistaken, both the PA-8800 and the PA-8900 processors are dual core.

$ machinfo
CPU info:
1 PA-RISC 8800 processor (800 MHz, 64 MB)
CPU version 5
2 logical processors (2 per socket)

$ model
9000/800/rp3410

Best regards,
Robert-Jan
