NAME

       likwid-perfscope  -  Frontend  for  the timeline mode of likwid-perfctr(1) that on-the-fly
       generates pictures from the measurements

SYNOPSIS

       likwid-perfscope [-h] [-cores <cpu_list>] [-freq <frequency>] [-group <eventset>]

DESCRIPTION

       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.

OPTIONS

       -h     prints a help message to standard output, then exits.

       -cores  <cpu_list>
              measures the given group on given CPUs in <cpu_list>

       -freq  <frequency>
              reads the current performance values every <frequency>. Available suffixes are  's'
              and 'ms', e.g. 500ms. Default value is 1s

       -group  <eventset>
              defines  the  events  and  counters  that  should  be  read. Possible values can be
              gathered from likwid-perfctr(1).  Default is group 'FLOPS_DP'

EXAMPLE

       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.
