LSCPU(1) User Commands LSCPU(1)
NAME
lscpu - display information about the CPU architecture
SYNOPSIS
lscpu [-a|-b|-c] [-x] [-s directory] [-e [=list]|-p [=list]]
lscpu -h|-V
DESCRIPTION
lscpu gathers CPU architecture information from sysfs and /proc/cpuinfo. The command output can be optimized for parsing or for easy readability by humans.
The information includes, for example, the number of CPUs, threads, cores, sockets, and Non-Uniform Memory Access (NUMA) nodes. There is also information about the CPU caches and cache sharing, family, model, bogoMIPS, byte order, and stepping.
Options that result in an output table have a list argument. Use this argument to customize the command output. Specify a comma-separated list of column labels to limit the output table to only the specified columns, arranged in the specified
order. See COLUMNS for a list of valid column labels. The column labels are not case sensitive.
Not all columns are supported on all architectures. If an unsupported column is specified, lscpu prints the column but does not provide any data for it.
COLUMNS
CPU The logical CPU number of a CPU as used by the Linux kernel.
CORE The logical core number. A core can contain several CPUs.
SOCKET The logical socket number. A socket can contain several cores.
BOOK The logical book number. A book can contain several sockets.
NODE The logical NUMA node number. A node may contain several books.
CACHE Information about how caches are shared between CPUs.
ADDRESS
The physical address of a CPU.
ONLINE Indicator that shows whether the Linux instance currently makes use of the CPU.
CONFIGURED
Indicator that shows if the hypervisor has allocated the CPU to the virtual hardware on which the Linux instance runs. CPUs that are configured can be set online by the Linux instance. This column contains data only if your hardware sys-
tem and hypervisor support dynamic CPU resource allocation.
POLARIZATION
This column contains data for Linux instances that run on virtual hardware with a hypervisor that can switch the CPU dispatching mode (polarization). The polarization can be:
horizontal The workload is spread across all available CPUs.
vertical The workload is concentrated on few CPUs.
For vertical polarization, the column also shows the degree of concentration, high, medium, or low. This column contains data only if your hardware system and hypervisor support CPU polarization.
OPTIONS
-a, --all
Include lines for online and offline CPUs in the output (default for -e). This option may only specified together with option -e or -p.
-b, --online
Limit the output to online CPUs (default for -p). This option may only be specified together with option -e or -p.
-c, --offline
Limit the output to offline CPUs. This option may only be specified together with option -e or -p.
-e, --extended [=list]
Display the CPU information in human readable format.
If the list argument is omitted, all columns for which data is available are included in the command output.
When specifying the list argument, the string of option, equal sign (=), and list must not contain any blanks or other white space. Examples: ’-e=cpu,node’ or ’--extended=cpu,node’.
-h, --help
Display help information and exit.
-p, --parse [=list]
Optimize the command output for easy parsing.
If the list argument is omitted, the command output is compatible with earlier versions of lscpu. In this compatible format, two commas are used to separate CPU cache columns. If no CPU caches are identified the cache column is omitted.
If the list argument is used, cache columns are separated with a colon (:).
When specifying the list argument, the string of option, equal sign (=), and list must not contain any blanks or other white space. Examples: ’-p=cpu,node’ or ’--parse=cpu,node’.
-s, --sysroot directory
Gather CPU data for a Linux instance other than the instance from which the lscpu command is issued. The specified directory is the system root of the Linux instance to be inspected.
-x, --hex
Use hexadecimal masks for CPU sets (for example 0x3). The default is to print the sets in list format (for example 0,1).
-V, --version
Display version information and exit.
BUGS
The basic overview about CPU family, model, etc. is always based on the first CPU only.
Sometimes in Xen Dom0 the kernel reports wrong data.
On virtual hardware the number of cores per socket, etc. can be wrong.
