Abstract

Specialization of datacenter resources brings performance and energy improvements in response to the growing scale and diversity of cloud applications. Yet heterogeneous hardware adds complexity and volatility to latency-sensitive applications. A resource allocation mechanism that leverages architectural principles can overcome both of these obstacles. We integrate research in heterogeneous architectures with recent advances in multi-agent systems. Embedding architectural insight into proxies that bid on behalf of applications, a market effectively allocates hardware to applications with diverse preferences and valuations. Exploring a space of heterogeneous datacenter configurations, which mix server-class Xeon and mobile-class Atom processors, we find an optimal heterogeneous balance that improves both welfare and energy-efficiency. We further design and evaluate twelve design points along the Xeon-to-Atom spectrum, and find that a mix of three processor architectures achieves a 12× reduction in response time violations relative to equal-power homogeneous systems.
管理具有异构微架构的数据中心的市场机制
数据中心资源的专业化带来了性能和能源的改进,以响应云应用程序不断增长的规模和多样性。然而,异构硬件增加了对延迟敏感的应用程序的复杂性和波动性。利用体系结构原则的资源分配机制可以克服这两个障碍。我们将异构体系结构的研究与多智能体系统的最新进展相结合。将体系结构洞察力嵌入到代表应用程序竞标的代理中,市场可以有效地将硬件分配给具有不同偏好和估值的应用程序。探索异构数据中心配置的空间,其中混合了服务器级Xeon和移动级Atom处理器,我们发现了一种优化的异构平衡,可以提高福利和能源效率。我们进一步设计和评估了Xeon-to-Atom光谱上的12个设计点,发现三种处理器架构的混合相对于等功率同构系统,在响应时间违反方面减少了12倍。

期刊介绍: ACM Transactions on Computer Systems (TOCS) presents research and development results on the design, implementation, analysis, evaluation, and use of computer systems and systems software. The term "computer systems" is interpreted broadly and includes operating systems, systems architecture and hardware, distributed systems, optimizing compilers, and the interaction between systems and computer networks. Articles appearing in TOCS will tend either to present new techniques and concepts, or to report on experiences and experiments with actual systems. Insights useful to system designers, builders, and users will be emphasized. TOCS publishes research and technical papers, both short and long. It includes technical correspondence to permit commentary on technical topics and on previously published papers.
