Need CPU information on superdome

[kiran b jadhav]

Need CPU information on superdome like cpu speed, core information...

How to get this information

model: ia64 hp superdome server SD32B

[kiran b jadhav]

I know with machinfo command we can get Clock speed but what about core information. How to know whether it is single core or dual core etc...

[Matti_Kurkela]

The machinfo output will identify the CPU model. Then use this table of Itanium 2 CPU models to see the number of cores.

http://en.wikipedia.org/wiki/Itanium_2#Released_processors

Alternatively, run "parstatus" and look at how many CPUs each cell has. Each cell has 4 physical CPU sockets, so if "parstatus" says the cell has 8 CPUs, then those must be 4 dual-core CPUs.

Here is parstatus output:

This is dual core (Montvale) CPU.


The Intel series 9000 and 9100 are dual core, the 9300 series is quad-core (only for superdome 2).

[Torsten.]

BTW, if you see this line from your previous output:


cab0,cell1 Active Base 8/0/8 40.0/0.0 - no yes 0


you see 8 cores per cell, but the cell has 4 slots - must be a dual core CPU.

Hi,

FYI in case you need this too;

Here's the Superdome Quickspec that gives a nice overview:
