likwid-perfscope - Frontend for the timeline mode of likwid-perfctr(1) that on-the-fly
generates pictures from the measurements
likwid-perfscope [-h] [-cores <cpu_list>] [-freq <frequency>] [-group <eventset>]
likwid-perfscope is a command line application written in Perl that uses the timeline
daemon mode of likwid-perfctr(1) to create on-the-fly pictures with the current
measurements. It uses the feedGnuplot(1) script to send the current data to gnuplot.
-h prints a help message to standard output, then exits.
measures the given group on given CPUs in <cpu_list>
reads the current performance values every <frequency>. Available suffixes are 's'
and 'ms', e.g. 500ms. Default value is 1s
defines the events and counters that should be read. Possible values can be
gathered from likwid-perfctr(1). Default is group 'FLOPS_DP'
1. Monitor double precision floating-point operations:
likwid-perfscope -group FLOPS_DP -cores 0-3 -freq 500ms
Executes likwid-perfctr on the first four cores. The values are read every 500ms are
forwarded to gnuplot using the feedGnuplot script.
