云计算环境下HPC应用的节能调度

Energy-Efficient Scheduling of HPC Applications in Cloud Computing Environments

Saurabh Kumar Garg, Chee Shin Yeo, Arun Anandasivam, Rajkumar Buyya

摘要:

高性能计算(HPC)在商业和消费者IT应用中的使用正变得越来越普遍。他们需要能够快速、可扩展地访问高端计算功能。云计算承诺使用数据中心提供这样的计算基础设施,以便HPC用户可以根据需要从世界任何地方的云访问应用程序和数据,并根据他们使用的内容付费。然而,不断增长的需求急剧增加了数据中心的能源消耗,这已成为一个关键问题。高能耗不仅意味着高能源成本,这将降低云提供商的利润率,而且还意味着高碳排放,这对环境来说是不可持续的。因此,需要节能的解决方案,不仅从云提供商的角度,而且从环境的角度来解决能源消耗的高增长。为了解决这个问题,我们提出了接近最佳的调度策略,利用跨多个数据中心的云提供商的异构性。我们考虑了许多能源效率因素,如能源成本、碳排放率、工作负载和CPU能效,这些因素在不同的数据中心中会根据位置、架构设计和管理系统而变化。与基于利润的调度政策相比,我们基于碳/能源的调度政策能够实现平均高达30%的能源节约,从而实现更高的利润和更少的碳排放。

英文摘要:

The use of High Performance Computing (HPC) in commercial and consumer IT applications is becoming popular. They need the ability to gain rapid and scalable access to high-end computing capabilities. Cloud computing promises to deliver such a computing infrastructure using data centers so that HPC users can access applications and data from a Cloud anywhere in the world on demand and pay based on what they use. However, the growing demand drastically increases the energy consumption of data centers, which has become a critical issue. High energy consumption not only translates to high energy cost, which will reduce the profit margin of Cloud providers, but also high carbon emissions which is not environmentally sustainable. Hence, energy-efficient solutions are required that can address the high increase in the energy consumption from the perspective of not only Cloud provider but also from the environment. To address this issue we propose near-optimal scheduling policies that exploits heterogeneity across multiple data centers for a Cloud provider. We consider a number of energy efficiency factors such as energy cost, carbon emission rate, workload, and CPU power efficiency which changes across different data center depending on their location, architectural design, and management system. Our carbon/energy based scheduling policies are able to achieve on average up to 30% of energy savings in comparison to profit based scheduling policies leading to higher profit and less carbon emissions.
