EAGER: Design and Implementation of a Renewable Adaptive Cluster

数据中心丰富了地球，为数十亿人提供了电子商务和网络搜索等服务。然而，数据中心不断增长的碳足迹加剧了气候变化，从长远来看，可能会损害社会对整个领域的看法。我们正在进行的工作为可持续的数据中心建立机制，即在保持低碳足迹的同时盈利的数据中心。在智力上，这项工作贡献了新的分析模型，将数据中心的碳足迹与其利用率和能源成本联系起来。这些模型必须考虑复杂的问题，如太阳能和风能中断、繁重的尾部和日间电子商务工作负载以及数据中心内的工作负载和能量平衡(例如，动态关闭服务器和DVFS)。此外，模型必须是整体的，从利润的角度解释这些因素。就广泛的影响而言，这项工作将提高数据中心驱动的计算的经济竞争力和可持续性。

Datacenters have enriched the planet, making services like e-commerce and web search available to billions. However, the growing carbon footprint of datacenters adds to climate change and, in the long term, could harm society's perception of the whole field. Our ongoing work builds mechanisms for sustainable datacenters, i.e., datacenters that profit while maintaining low carbon footprints. Intellectually, the work contributes new analytic models that relate a datacenter's carbon footprint to its utilization and energy costs. These models must consider complicated issues like solar- and wind-energy outages, heavy-tail and diurnal e-commerce workloads, and workload and energy balancing within datacenters (e.g., dynamically powering servers off and DVFS). Further, the models must be holistic, explaining these factors in terms of profit. In terms of broad impacts, this work will improve the economic competitiveness and sustainability of datacenter-driven computing.
