1. A method, in a data processing system, for minimizing system power in the data processing system with fast convergence, the method comprising:
determining, by a management control unit in the data processing system, a current aggregate system power value using a current thermal threshold value, wherein the current aggregate system power is determined by the method comprising:
calculating, by the management control unit, a total processor power value;calculating, by the management control unit, a revolutions per minute required for a fan to reach the current thermal threshold value;using, by the management control unit, the revolutions per minute value, identifying a fan power value; andcalculating, the management control unit, the current aggregate system power value by summing the total processor power value with the fan power value; for each potential thermal threshold value in a set of potential thermal threshold values, determining, by the management control unit, whether there is a potential thermal threshold value that results in a potential aggregate system power value that is lower than the current aggregate system power value; and responsive to identifying an optimal potential thermal threshold value from the set of potential thermal threshold values that results in minimum aggregate system power value that is lower than the current aggregate system power value, setting, by the management control unit, the optimal potential thermal threshold value as a new thermal threshold value, wherein by setting the optimal potential thermal threshold value that results in minimum aggregate system power as the new thermal threshold value for a current time period, a fan speed of the fan coupled to the data processing system either increases, decreases, or stays the same. |
