56280 多租户公有云是云计算的一种重要组成形式. Multi-tenant public cloud is an important sector of cloud computing.
56281 近年来,多租户公有云数据中心在如火如荼发展的同时,其过低资源使用率所导致的巨大能耗浪费也引起了社会的高度关注. While it has witnessed anunprecedented proliferation in the past years, its low resource utilization that incurs enormous energy waste hasreceived great attention.
56282 然而,由于多租户公有云的资源通常以"包年包月"的租赁形式预留给租户,云服务提供商无法通过关闭空闲服务器等常用能耗管理方法来降低数据中心能耗. Since the resource of multi-tenant datacenters is typically rented to the tenants in areserved manner, the cloud provider is unable to reduce the energy consumption or improve resource utilizationvia turning down idle servers.
56283 针对这一难题,本文提出了面向多租户数据中心资源回收利用的激励机制来提升多租户数据中心能效. To address this challenge, this paper proposes an efficient incentive mechanismto stimulate the recycling of reserved idle resources.
56284 该机制以经济激励的形式来回收利用租户空闲预留型资源,即云服务提供商向租户支付合适的经济补偿,从而回收租户空闲预留型资源,并充分利用其运行其他云计算服务(如电商和搜索服务). Specifically, by economically compensating the tenants,the reserved resources that are idle can be recycled by the cloud providers to host other cloud applications,such as e-commerce and search engine.
56285 基于Lyapunov方法,本文设计并分析了一种面向租户预留资源回收利用的动态定价算法,该算法无需预测系统未来信息便可作出在线定价决策,并且在保障系统稳定性的同时使得云服务提供商长期成本无限接近于理论最低值. Taking advantage of the Lyapunov optimization method, this paperrigorously designs and analyzes a dynamic pricing scheme for the recycled reserved resources. Without requiringthe future information as a priori, the proposed pricing scheme can make online decisions to optimize the long?term operational cost of the cloud provider, while still maintaining the stability of the system.
56286 通过严格的数学证明以及由真实数据驱动的仿真实验,本文验证了所提出的激励机制在回收利用租户空闲资源方面的有效性. Both rigoroustheoretical analysis and extensive trace-driven simulations verify the efficacy of the proposed incentive mechanism.
56287 除法运算是基本四则运算之一,如何进行快速除法一直是电子计算机、嵌入式系统和其他新型计算系统广受关注的问题. Division is one of the four basic operations. It is a very important operation in the field of numericalcalculation, such as numerical calculation, large integer decomposition and so on. How to divide quickly hasbeen a hot issue in electronic computers, embedded systems and other new computing systems.
