调试应用程序的电源有一系列好处，从最大限度地减少热热点到降低CPU故障的可能性。在这项工作中，我们证明了电源调试的必要性，并证明了并行应用程序的性能调试并不能自动保证多个内核之间的功率平衡。我们使用两个案例研究基准进行了实验并展示了我们的结果，来自Splash-2的Volrend和来自Parsec-1.0的BodyTrack。
Debugging an application for power has a wide array of benefits ranging from minimizing the thermal hotspots to reducing the likelihood of CPU malfunction. In this work, we justify the need for power debugging, and show that performance debugging of a parallel application does not automatically guarantee power balance across multiple cores. We perform experiments and show our results using two case study benchmarks, Volrend from Splash-2 and Bodytrack from Parsec-1.0.
