The following example shows sample output from the date command.

$ date
Fri Jun  1 16:07:44 MDT 2012
$

How to Display a System's Host ID Number

To display the host ID number in a numeric (hexadecimal) format, use the hostid command.

Example 1-2 Displaying a System's Host ID Number

The following example shows sample output from the hostid command.

$ hostid
80a5d34c

Displaying a System's Architecture and Processor Type

The following examples show the output of the isainfo and isalist commands when run on x86 and SPARC based systems.

Example 1-3 Displaying a System's Architecture Type

The following examples show how to display the architecture type and names of the native instruction sets for applications that are supported by the current operating system.

The following output is from an x86 based system:

$ isainfo
amd64 i386

The following output is from a SPARC based system:

$ isainfo
sparcv9 sparc

The isainfo -v command displays 32-bit and 64-bit application support. For example, the following output if from a SPARC based system:

$ isainfo -v
64-bit sparcv9 applications
        asi_blk_init
32-bit sparc applications
        asi_blk_init v8plus div32 mul32

How to Display a System's Product Name

The -b option to the prtconf command enables you to display the product name of a system. For more information, see the prtconf(1M) man page.

To display the product name for your system, use the prtconf command with the -b option, as follows:
```
$ prtconf -b
```

Example 1-5 SPARC: Displaying a System's Product Name

This example shows sample output from the prtconf -b command on a SPARC based system.

$ prtconf -b
name:  ORCL,SPARC-T4-2
banner-name:  SPARC T4-2

idprom: 01840014.4fa02d28.00000000.a02d28de.00000000.00000000.00000000.00000000
openprom model:  SUNW,4.33.0.b
openprom version: 'OBP 4.33.0.b 2011/05/16 16:26'

How to Display a System's Installed Memory

To display the amount of memory that is installed on your system, use the prtconf command.

Example 1-6 Displaying a System's Installed Memory

The following example shows sample output from the prtconf command. The grep Memory command selects output from the prtconf command to display memory information only.

$ prtconf | grep Memory
Memory size: 523776 Megabytes

How to Display Default and Customized Property Values for a Device

To display both the default and customized property values for devices, use the prtconf command with the -u option. For more information about this option, see the prtconf(1M) man page.

Display the default and customized properties of a driver.conf file.
```
$ prtconf -u
```
The output of the prtconf -u command displays the default and customized properties for all of the drivers that are on the system.

Example 1-7 SPARC: Displaying Default and Custom Device Properties

This example shows the default and custom properties for the bge.conf file. Note that vendor-provided configuration files are located in the /kernel and /platform directories, while the corresponding modified driver configuration files are located in the /etc/driver/drv directory.

Identifying Information About Chip Multithreading Features

The psrinfo command has been modified to provide information about physical processors, in addition to information about virtual processors. This enhanced functionality has been added to identify chip multithreading (CMT) features. The new -p option reports the total number of physical processors that are in a system. Using the psrinfo -pv command will list all the physical processors that are in the system, as well as the virtual processors that are associated with each physical processor. The default output of the psrinfo command continues to display the virtual processor information for a system.

For more information, see the psrinfo(1M) man page.

For information about the procedures that are associated with this feature, see How to Display a System's Physical Processor Type.

How to Display a System's Physical Processor Type

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 that is associated with each physical processor. For example:

$ psrinfo -pv
The physical processor has 8 cores and 32 virtual processors (0-31)
  The core has 4 virtual processors (0-3)
  The core has 4 virtual processors (4-7)
  The core has 4 virtual processors (8-11)
  The core has 4 virtual processors (12-15)
  The core has 4 virtual processors (16-19)
  The core has 4 virtual processors (20-23)
  The core has 4 virtual processors (24-27)
  The core has 4 virtual processors (28-31)
    UltraSPARC-T1 (chipid 0, clock 1000 MHz)

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

$ psrinfo -pv
The physical processor has 2 virtual processors (0 1)
  x86 (AuthenticAMD 40F13 family 15 model 65 step 3 clock 2793 MHz)
        Dual-Core AMD Opteron(tm) Processor 2220        [ Socket: F(1207) ]
The physical processor has 2 virtual processors (2 3)
  x86 (AuthenticAMD 40F13 family 15 model 65 step 3 clock 2793 MHz)
        Dual-Core AMD Opteron(tm) Processor 2220        [ Socket: F(1207) ]

How to Display a System's Virtual Processor Type

Use the psrinfo -v command to display information about a system's virtual processor type.
```
$ psrinfo -v
```
On an x86 based system, use the isalist command to display the virtual processor type. For example:
```
$ isalist
amd64 pentium_pro+mmx pentium_pro pentium+mmx pentium i486 i386 i86
```

Example 1-12 SPARC: Displaying a System's Virtual Processor Type

This example shows how to display information about a SPARC based system's virtual processor type.

$ psrinfo -v
Status of virtual processor 28 as of: 09/13/2010 14:07:47
  on-line since 04/08/2010 21:27:56.
  The sparcv9 processor operates at 1400 MHz,
        and has a sparcv9 floating point processor.
Status of virtual processor 29 as of: 09/13/2010 14:07:47
  on-line since 04/08/2010 21:27:56.
  The sparcv9 processor operates at 1400 MHz,
        and has a sparcv9 floating point processor.

Example 1-13 SPARC: Displaying the Virtual Processor That Is Associated With Each Physical Processor on a System

The following example shows the output of the psrinfo command, when run with the -pv options on an Oracle SPARC T4-4 server. The output displays both the chip (physical processor) and the core information about the thread location. This information can be helpful in determining which physical CPU a thread is on, and how it is mapped at the core level.

$ psrinfo -pv
The physical processor has 8 cores and 64 virtual processors (0-63)
  The core has 8 virtual processors (0-7)
  The core has 8 virtual processors (8-15)
  The core has 8 virtual processors (16-23)
  The core has 8 virtual processors (24-31)
  The core has 8 virtual processors (32-39)
  The core has 8 virtual processors (40-47)
  The core has 8 virtual processors (48-55)
  The core has 8 virtual processors (56-63)
    SPARC-T4 (chipid 0, clock 2998 MHz)
The physical processor has 8 cores and 64 virtual processors (64-127)
  The core has 8 virtual processors (64-71)
  The core has 8 virtual processors (72-79)
  The core has 8 virtual processors (80-87)
  The core has 8 virtual processors (88-95)
  The core has 8 virtual processors (96-103)
  The core has 8 virtual processors (104-111)
  The core has 8 virtual processors (112-119)
  The core has 8 virtual processors (120-127)
