1. A computer system, comprising: a processor including: a first processing core; and a second processing core; a power control unit to provide a first clock signal to the first processing core and a second clock signal to the second processing core; and a computer readable storage medium to store scalability algorithm instructions, executable by the processor, to cause the processor to: initialize a performance indicator counter; operate at an initial frequency of the first clock signal for a first duration; determine, based on the performance indicator counter, a first performance value of the first processing core; operate at a second frequency of the first clock signal for a second duration; determine, based on the performance indicator counter, a second performance value of the first processing core; determine a performance scalability of the first processing core based on the initial performance value and the second performance value; modify at least one of the first clock signal and the second clock signal based on the performance scalability determined.
