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,
       ARM and POWER 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.  When compiled with NVIDIA_INTERFACE=true in  config.mk  and  the
       CUDA/CUPTI  library reachable at runtime, likwid-topology prints information about the Nvidia GPUs in the
       system.

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.
