Abstract:

Power budget is an important power constraint provided to guarantee the thermal reliability of an integrated system. In this work, we present DBP, a distributed power budgeting method, for dark silicon many-core systems. In DBP, there are two new techniques proposed to bring accurate and optimized power budgets in a distributed way. First, a distributed active core locating technique is developed to find an active core distribution that leads to a high-power budget. Second, a distributed power budget computing technique is introduced which computes the power budget for each active core accurately. Experiments show DBP outperforms the state-of-the-art power budgeting methods’ thermal safe power (TSP) and greedy dynamic power (GDP) on many-core dark silicon systems by providing a high and accurate power budget with low overhead and good scalability.
