ProcedureHow to Display a System's Physical Processor Type

  1. Use the psrinfo -p command to display the total number of physical processors on a system.


    $ psrinfo -p
1

    Use the psrinfo -pv command to display information about each physical processor on a system, and the virtual processor associated with each physical processor.


    $ psrinfo -pv
The UltraSPARC-IV physical processor has 2 virtual processors (8, 520)
The UltraSPARC-IV physical processor has 2 virtual processors (9, 521)
The UltraSPARC-IV physical processor has 2 virtual processors (10, 522)
The UltraSPARC-IV physical processor has 2 virtual processors (11, 523)
The UltraSPARC-III+ physical processor has 1 virtual processor (16)
The UltraSPARC-III+ physical processor has 1 virtual processor (17)
The UltraSPARC-III+ physical processor has 1 virtual processor (18)
The UltraSPARC-III+ physical processor has 1 virtual processor (19)

    When you use the psrinfo -pv command on an x86 based system, the following output is displayed:


    $ psrinfo -pv
The i386 physical processor has 2 virtual processors (0, 2)
The i386 physical processor has 2 virtual processors (1, 3)
