NAME
machinfo - print machine information
SYNOPSIS
machinfo [-v][-m]
DESCRIPTION
machinfo prints useful information about the machine. The output and format can change based on
product updates, os version, hardware platform or system configuration. See the Support section of this
manpage for more information on the recommended usage of
machinfo.
The output includes information about processors, firmware revisions, and amount of memory on the sys-
tem. This output consists of the HP-UX operating system’s view of the system configuration, as opposed to
the entire physical hardware platform. The information about processors and memory reflects the
configuration of the physical or virtual partition.
Options
machinfo recognizes the following options:
-v This option will cause machinfo
to print out extra details, such as the sizes of each indivi-
dual level of processor cache, and which optional features of the ISA (instruction set architec-
ture) are supported natively by the processors.
-m This option will cause machinfo to print out extra details about the memory configuration,
specifically the amount of interleaved memory (ILM) that is configured on the system. The
data printed will be the percentage of total memory that is configured as ILM. This data is cal-
culated using pstat_getlocality()
. Refer to the pstat_getlocality(2) manpage for more
information about ILM.
Support
The
machinfo command is delivered in /usr/contrib/bin
and, as indicated in hier (5),
/usr/contrib commands are unsupported.
The
machinfo command output is not suitable for parsing by scripts since its content and format is sub-
ject to change based on product updates, os version, hardware platform, and/or system configuration. The
Display Description section of this manpage describes how to obtain each set of information using other
supported interfaces or means.
Display Description
Five general sections of information are displayed by
machinfo:
CPU Info The CPU section shows information about CPUs on the system and how many of each type
there are.
Example:
Intel(R) Itanium(R) Processor 9350 (1.73 GHz, 24 MB)
4 cores, 8 logical processors per socket
4.79 GT/s QPI, CPU version E0
Active processor count:
8 sockets
32 cores (4 per socket)
32 logical processors (4 per socket)
LCPU attribute is disabled
The first three lines of the CPU information describe the physical characteristics of the pro-
cessors: CPU model, speed, cache size, cores/logical processors per socket, bus/interconnect
speed, and stepping (version).
The remaining CPU information describes how many processors, cores, and logical proces-
sors are currently active in the partition. If CPU hyperthreading is available, the current
LCPU attribute (enabled, disabled, or partially enabled) will also be displayed. The
number of logical processors will be the same as the number of cores if the LCPU attribute
is disabled or the processors are not LCPU capable. When the LCPU attribute is enabled,
the number of logical processors will be larger. The number of sockets indicates how many
processors have at least one core active in the partition; processors with no active cores are
not counted.
