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. .SH OPTIONS .TP .B \-h, \-\-\^help prints a help message to standard output, then exits. .TP .B \-v, \-\-\^version prints version information to standard output, then exits. .TP .B \-V, \-\-\^verbose sets the verbosity level of LIKWID's topology backend. Possible levels range from 0 to 3. .TP .B \-g prints topology information in ASCII art. Best viewed with monospaced font. .TP .B \-c, \-\-\^caches prints detailed information about cache hierarchy .TP .B \-C, \-\-\^clock measures and output the processor clock. This involves a longer run time of likwid-topology. .TP .B \-o, \-\-\^output 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. .SH AUTHOR Written by Thomas Roehl . .SH BUGS Report Bugs on . .SH "SEE ALSO" likwid-perfctr(1), likwid-features(1), likwid-pin(1),
