NAME

       likwid-powermeter - A tool to print power and clocking information on Intel CPUs

SYNOPSIS

       likwid-powermeter [-vhip] [-c <socket_list>] [-s <duration_in_seconds>] [-M <access_mode>]

DESCRIPTION

       likwid-powermeter  is  a  command  line application to get the energy comsumption of Intel
       RAPL capable processors.  It also prints  information  about  TDP  and  Turbo  Mode  steps
       supported.   The  Turbo Mode information works on all Turbo mode enabled Intel processors.
       The tool can be either used in stethoscope mode for a specified duration or as  a  wrapper
       to  your  application  measuring  your  complete run. RAPL works on a per package (socket)
       base.  Please note that the RAPL counters are also  accessible  as  normal  events  within
       likwid-perfctr.

OPTIONS

       -v     prints version information to standard output, then exits.

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

       -c  <socket_list>
              set on which sockets the RAPL interface is accessed. comma-separated list of socket
              IDs

       -p     prints out information about dynamic clocks  and  CPI  information  on  the  socket
              measured. Uses likwid-perfctr internally.

       -i     prints out information TDP and Turbo mode steps

       -M  <access_mode>
              set  the  access method. 0 for direct access to MSR/RAPL registers, 1 for using the
              accessDaemon.

       -s  <duration_in_seconds>
              measure the power for a specific time (default 2s)
