NAME

       likwid-topology - print thread and cache topology

SYNOPSIS

       likwid-topology [-hvgcC] [-V level] [-o output_file]

DESCRIPTION

       likwid-topology  is  a  command line application to print the thread and cache topology on
       multicore x86 processors. Used with mono spaced fonts it can draw the  processor  topology
       of  a  machine  in  ascii  art.  Beyond topology likwid-topology determines the clock of a
       processor and prints detailed information about the caches hierarchy.

OPTIONS

       -h, --help
              prints a help message to standard output, then exits.

       -v, --version
              prints version information to standard output, then exits.

       -V, --verbose <level>
              sets the verbosity level of LIKWID's topology backend. Possible levels range from 0
              to 3.

       -g     prints topology information in ASCII art. Best viewed with monospaced font.

       -c, --caches
              prints detailed information about cache hierarchy

       -C, --clock
              measures and output the processor clock. This involves a longer run time of likwid-
              topology.

       -o, --output <file>
              write the output  to  file  instead  of  stdout.   Likwid  applies  filter  scripts
              according  to  filename suffix.  Currently available scripts are csv. You can place
              additional filter scripts in /usr/share/likwid/filter.
