Managing Energy and Server Resources in Hosting Centers

by Jeffrey S. Chase, Darrell C. Anderson, Prachi N. Thakar, Amin M. Vahdat - In Proceedings of the 18th ACM Symposium on Operating System Principles (SOSP , 2001
"... Interact hosting centers serve multiple service sites from a common hardware base. This paper presents the design and implementation of an architecture for resource management in a hosting center op-erating system, with an emphasis on energy as a driving resource management issue for large server cl ..."

Tinydb: An acquisitional query processing system for sensor networks

by Samuel R. Madden, Michael J. Franklin, Joseph M. Hellerstein, Wei Hong - ACM Trans. Database Syst , 2005
"... We discuss the design of an acquisitional query processor for data collection in sensor networks. Acquisitional issues are those that pertain to where, when, and how often data is physically acquired (sampled) and delivered to query processing operators. By focusing on the locations and costs of acq ..."
Abstract - Cited by 626 (8 self) - Add to MetaCart
of acquiring data, we are able to significantly reduce power consumption over traditional passive systems that assume the a priori existence of data. We discuss simple extensions to SQL for controlling data acquisition, and show how acquisitional issues influence query optimization, dissemination

Live Migration of Virtual Machines

by Christopher Clark, Keir Fraser, Steven H, Jakob Gorm Hansen, Eric Jul, Christian Limpach, Ian Pratt, Andrew Warfield - In Proceedings of the 2nd ACM/USENIX Symposium on Networked Systems Design and Implementation (NSDI , 2005
"... Migrating operating system instances across distinct physical hosts is a useful tool for administrators of data centers and clusters: It allows a clean separation between hardware and software, and facilitates fault management, load balancing, and low-level system maintenance. By carrying out the ma ..."

The Case for Energy-Proportional Computing

by Luiz André Barroso, Urs Hölzle
"... Energy-proportional designs would enable large energy savings in servers, potentially doubling their efficiency in real-life use. Achieving energy proportionality will require significant improvements in the energy usage profile of every system component, particularly the memory and disk subsystems. ..."

performance improvements. Energy management has now become a key issue for servers and data center operations, focusing on the reduction of all energy-related costs, including capital, operating expenses, and environmental impacts. Many

Matchmaking: Distributed Resource Management for High Throughput Computing

by Rajesh Raman, Miron Livny, Marvin Solomon - In Proceedings of the Seventh IEEE International Symposium on High Performance Distributed Computing , 1998
"... Conventional resource management systems use a system model to describe resources and a centralized scheduler to control their allocation. We argue that this paradigm does not adapt well to distributed systems, particularly those built to support high-throughput computing. Obstacles include heteroge ..."

approach to resource management in distributed environment with decentralized ownership of resources. Novel aspects of the framework include a semi-structured data model that combines schema, data, and query in a simple but powerful specification language, and a clean separation of the matching

Efficient power control via pricing in wireless data networks

by Cem U. Saraydar, Narayan B. M, Senior Member, David J. Goodman - IEEE Trans. on Commun , 2002
"... Abstract—A major challenge in the operation of wireless communications systems is the efficient use of radio resources. One important component of radio resource management is power control, which has been studied extensively in the context of voice communications. With the increasing demand for wir ..."

Cassandra- A Decentralized Structured Storage System

by Avinash Lakshman, Prashant Malik
"... Cassandra is a distributed storage system for managing very large amounts of structured data spread out across many commodity servers, while providing highly available service with no single point of failure. Cassandra aims to run on top of an infrastructure of hundreds of nodes (possibly spread acr ..."

across different data centers). At this scale, small and large components fail continuously. The way Cassandra manages the persistent state in the face of these failures drives the reliability and scalability of the software systems relying on this service. While in many ways Cassandra resembles a

No power struggles: Coordinated multi-level power management for the data center

by Ramya Raghavendra, Parthasarathy Ranganathan, Vanish Talwar, Zhikui Wang, Xiaoyun Zhu - in ASPLOS , 2008
"... Power delivery, electricity consumption, and heat management are becoming key challenges in data center environments. Several past solutions have individually evaluated different techniques to address separate aspects of this problem, in hardware and software, and at local and global levels. Unfortu ..."

An Integrated Congestion Management Architecture for Internet Hosts

by Hari Balakrishnan, Hariharan S. Rahul, Srinivasan Seshan - In Proc. ACM SIGCOMM , 1999
"... This paper presents a novel framework for managing network congestion from an end-to-end perspective. Our work is motivated by several trends in traffic patterns that threaten the long-term stability of the Internet. These trends include the use of multiple independent concurrent flows by Web app ..."

applications and the increasing use of transport protocols and applications that do not adapt to congestion. We present an end-system architecture centered around a Congestion Manager (CM) that ensures proper congestion behavior and allows applications to easily adapt to network congestion. Our framework

Fjording the Stream: An Architecture for Queries over Streaming Sensor Data

by Samuel Madden , Michael J. Franklin , 2002
"... If industry visionaries are correct, our lives will soon be full of sensors, connected together in loose conglomerations via wireless networks, each monitoring and collecting data about the environment at large. These sensors behave very differently from traditional database sources: they have inter ..."

These limitations make traditional database systems inappropriate for queries over sensors. We present the Fjords architecture for managing
