NAME
likwid-setFrequencies - print and manage the clock frequency of CPU cores
SYNOPSIS
likwid-setFrequencies [-hpl] [-c <cpu_list,_socket_list_or_expression>] [-g <governor>] [-f <frequency>]
DESCRIPTION
likwid-setFrequencies is a command line application to set the clock frequency of CPU cores. Since only priviledged users are allowed to change the frequency of CPU cores, the application works in combination with a daemon likwid-setFreq. The daemon needs the suid permission bit to be set in order to manipulate the sysfs entries. With likwid- setFrequencies the clock of all cores inside a the cpu_list or affinity domain can be set to a specific frequency or governor at once.
OPTIONS
-h prints a help message to standard output, then exits. -p prints the current frequencies for all CPU cores -l prints all configurable frequencies -c <cpu_list,_socket_list_or_expression> set the affinity domain where to set the frequencies. Common are N (Node), SX (Socket X), CX (Cache Group X) and MX (Memory Group X). For detailed information about affinity domains see likwid-pin(1) -g <governor> set the governor of all CPU cores inside the affinity domain. Current governors are ondemand, performance, turbo. Default is ondemand -f <frequency> set a fixed frequency at all CPU cores inside the affinity domain. Implicitly sets userspace governor for the cores.
