Information

likwid-setFreq is a command line application that mediates the actual setting of CPU cores' frequency and governor for likwid-setFrequencies. Since only users with root priviledges are allowed to change the frequency of CPU cores, likwid-setFreq needs to be suid-root.

Setup

Setting the suid-root bit:
root: # chown root:root likwid-setFreq root: # chmod u+s likwid-setFreq
