Hello,

I want to find out if my processor is single or dual core processor. Is there a way to find out this?
Thanks,

Try the "prtconf" command.

It gives information like ...

System Model: IBM,7043-260 Machine Serial Number: 10FB42D Processor Type: PowerPC_POWER3 Number Of Processors: 2 Processor Clock Speed: 200 MHz CPU Type: 64-bit Kernel Type: 64-bit LPAR Info: -1 NULL Memory Size: 1024 MB Good Memory Size: 1024 MB Platform Firmware level: Not Available Firmware Version: IBM,SPX01264 Console Login: enable Auto Restart: 

true Full Core: 

false

...

But the OS always treats or sees each core as separate processor right ? In which case you may have to find out from processor name/model number etc.
Also from ODM you can get number of processors, its name, physical location etc ...

odmget -q
"PdDvLn LIKE processor/*" CuDv

Lists all processors

and ...

odmget -q
"PdDvLn LIKE processor/* AND name=proc0" CuDv

Gives a specific processor, but it is more about Physical location etc, nothing about single/dual core etc.

maybe check in "lscfg -vp" output...

I've checked is on LPARs on two servers - p55A and p570 - both servers 8 CPUs and seems that in p55A there are 2 4-core CPUs and in 570 4 2-core CPUs.
$ lsattr -El sys0 -a modelname
modelname IBM,9117-570 Machine name False

This does not seem to be accurate, for me. I have a machine I know is a p550 with 2 quad-core processors (no LPARs):

/ #>lsattr -El sys0 -a modelname
modelname IBM,9133-55A Machine name False

/ #>lparstat -i|grep Active\ Phys
Active Physical CPUs in system : 8

/ #>lscfg -vp | grep WAY
2-WAY PROC CUOD :
2-WAY PROC CUOD :

/ #>lscfg -vp |grep proc
proc0 Processor
proc2 Processor
proc4 Processor
proc6 Processor
proc8 Processor
proc10 Processor
proc12 Processor
proc14 Processor

And the further detailed lscfg -vp output shows:
2-WAY PROC CUOD :
Record Name.................VINI
Flag Field..................XXPF
Hardware Location Code......U787B.001.DNWC2F7-P1-C9
Customer Card ID Number.....8313
Serial Number...............YL10HA68E008
FRU Number..................10N6469
Part Number.................10N6469
As you can see, the part number is 10N6469, which clearly is a quad-core cpu:

Additionally, some servers I've checked don't show any "x-WAY" in the lscfg -vp output (`lscfg -vp |grep WAY' shows nothing, even though I know it's a dual or quad-core CPU.

IINM Power5 came with dual core... I have not come across any p-Series box with a Quad core processor.

I generally use "lscfg | grep proc" to list the processors...

Hi,

Power5 and Power6 processors are both Dual Core - Dual Threads.
The next Power7 should have 8 cores and each core can execute 4 threads (comes 2010) but less frequency (3.2Ghz max instead of 5.0Ghz on the power6).
