Abstract :
In this paper, we present a novel solution to the Voltage Selection Problem for large multi-core architectures. Compared to previous algorithms, ours provides similar results, but is more than 10x faster. This run-time improvement is important, especially for large multi-core platforms with hundreds of cores. We evaluate our algorithm in the context of a process, voltage, and temperature (PVT) variation-aware energy optimization framework.
