SYNOPSIS

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.
