Energy Efficient Computer Process

A method for optimizing energy utilization of a computer processing device, the method comprising:

• sampling power measurements and hardware counters for given hardware components at a regular interval;
• storing the power measurements for later analysis;
• computing metrics for a sample window based on a current power consumption, current power limits, and hardware counters for given system hardware components;
• comparing the current sample metrics against a metric threshold;
• classifying the current sample based on the comparison of the current sample metrics against a metric threshold;
• assigning a classification type based on classifying the current sample;
• determining if an actual number of a computational intensity characteristic exceeds a maximum allowed reference number in a sample window for the classification type;
• if the actual number of a computational intensity characteristic exceeds the maximum for the classification type, computing a new maximum allowed for the classification type;
• and
• constraining the hardware components to the new maximum power measurements.
