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.
