Analysis of Power-Saving Techniques over a Large Multi-use Cluster

Reduction of power consumption for any computer system is now an important issue, although this should be done in a manner that is not detrimental to the user base. We present a number of policies that can be applied to multi-use clusters where computers are shared between interactive users and high-throughput computing. We evaluate policies by trace-driven simulations in order to determine the effects on power consumed and impact on high-throughput users. We demonstrate that these policies could save ~60% more energy for the high-throughput jobs over our current cluster policies.
