pls find the output and advise us $ ioscan -k -C processor H/W Path Class Description =================================== 0/120 processor Processor 0/121 processor Processor 0/122 processor Processor 0/123 processor Processor 0/124 processor Processor 0/125 processor Processor 0/126 processor Processor 0/127 processor Processor 2/120 processor Processor 2/121 processor Processor 2/122 processor Processor 2/123 processor Processor 2/124 processor Processor 2/125 processor Processor 2/126 processor Processor 2/127 processor Processor

pls help me , how to find the cpu core.

The command you ran above shows you exactly the number of CPU cores active on your system.  If that is not the information you want, what exactly do you want?

If this is an Itanium system you can also try running the 'machinfo' command.

# /usr/contrib/bin/machinfo -v -m

[Torsten.]

"machinfo" is the command:

#

# machinfo
CPU info:
  8 s (1.6 GHz, 20 MB)
          4794 MT/s bus, CPU version 4
          32 logical processors (4 per socket)

here you see 8 quad core CPU modules = 32 cores.

It would help if you could format this exactly how it appears on HP-UX.  It's kind of hard to count the lines, which is the number of processors == cores.

You can use the post's Options > Edit Reply to fix your post.

please find the below machinfo command output ,

CPU info:
  2 Intel(R)  Itanium(R)  Processor 9340s (1.6 GHz, 20 MB)
          4.79 GT/s QPI, CPU version E0
          16 logical processors (8 per socket)

From the above output we conclude,

2 physical processor

core - how to view the core

total processor count -16

>     16 logical processors (8 per socket)

Hmm, the only way to get 8 is with hyperthreading?

 >2 physical processor

No, just two sockets.

>core - how to view the core

If you have 2 sockets, you have 8 cores.

[rajesh73]

pls find the below output

 1 Intel(R)  Itanium(R)  Processor 9340 (1.6 GHz, 15 MB)
          4.79 GT/s QPI, CPU version E0
          6 logical processors (6 per socket)

from the above output , please clarify my understanding right or wrong

1 socker

core - core (6 per scoket means how put the core)

total processor is 6
