likwid-topology - print thread and cache topology
likwid-topology [-hvgcC] [-V level]
[-o output_file]
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.
- -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.
