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.
