Processor and core informations on hp ux rx 3600 servers.

Hi Experts,

 

How to determine the total number of physical cpus and number od cores on hp ux. I executed the command ioscan -fnC processor and machinfo. From these outs how we can conclude the total number of physical cpus and number od cores.

 

# ioscan -fnC processor
Class       I  H/W Path  Driver    S/W State H/W Type  Description
===================================================================
processor   0  120       processor CLAIMED   PROCESSOR Processor
processor   1  121       processor CLAIMED   PROCESSOR Processor

 

# machinfo |more
CPU info:
   Number of CPUs = 2
   Number of enabled CPUs = 2
   Number of enabled sockets = 1
   Cores per socket = 2
   Clock speed = 1595 MHz
   Bus speed   = 532 MT/s
   CPUID registers
      vendor information =       "GenuineIntel"
      processor serial number =  0x0000000000000000
      processor version info =   0x0000000020000704
         architecture revision:       0
         processor family:           32   Intel(R) Itanium 2 9000 series
         processor model:             0   Intel(R) Itanium 2 9000 series

Thanks in Advance.

machinfo tells you:

  Number of CPUs = 2    Number of enabled CPUs = 2
  Number of enabled sockets = 1
  Cores per socket = 2

 

You have two cores == two CPUs.  Only one socket.

Thanks for your support.

 

Kindly let me know ioscan ouput stands for, is it for total number of cores or number of processors and for other hardware model's also how we can clonclude.

Same as machinfo:  cores == processors

With the possible exception if hyperthreading is turned on?

 

>for other hardware models also how we can conclude?

 

It should be similar.
