NAME
       lscpu - CPU architecture information helper

SYNOPSIS
       lscpu [-hp]

DESCRIPTION
       lscpu  gathers  CPU  architecture information like number of CPUs, threads, cores, sockets, NUMA nodes, information about
       CPU caches, CPU family, model and stepping from sysfs and /proc/cpuinfo, and prints it in human-readable format. Alterna-
       tively,  it  can print out in parsable format including how different caches are shared by different CPUs, which can also
       be fed to other programs.

OPTIONS
       -h, --help
              Print a help message.

       -p, --parse
              Print out in parsable instead of printable format.

BUGS
       The basic overview about CPU family, model, etc. is always based on the first CPU only.

       Sometimes in Xen Dom0 kernel reports wrong data.
