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.
