Autonomic Management of Clustered Applications Abstract

by Sara Bouchenak, Noël De Palma
"... Distributed software environments are increasingly complex and difficult to manage, as they integrate various legacy software with proprietary management interfaces. Moreover, the fact that management tasks are performed by humans leads to many configuration errors and low reactivity. This paper pre ..."

distributed applications and to autonomously reconfigure them as required. We report our experiments in using Jade for the management of a clustered J2EE application.

An Overview of Workflow Management: From Process Modeling to Workflow Automation Infrastructure

by Diimitrios Georgakopoulos, Mark Hornick, Amit Sheth - DISTRIBUTED AND PARALLEL DATABASES , 1995
"... Today’s business enterprises must deal with global competition, reduce the cost of doing business, and rapidly develop new services and products. To address these requirements enterprises must constantly reconsider and optimize the way they do business and change their information systems and appl ..."

commercial workflow technology and extend the scope and mission of workflow management systems to support increased workflow automation in complex real-world environments involving heterogeneous, autonomous, and distributed information systems. In particular, we discuss how distributed object management

Motivation through the Design of Work: Test of a Theory. Organizational Behavior and Human Performance,

by ] Richard Hackman , Grec R Oldham , 1976
"... A model is proposed that specifies the conditions under which individuals will become internally motivated to perform effectively on their jobs. The model focuses on the interaction among three classes of variables: (a) the psychological states of employees that must be present for internally motiv ..."

in the management literature, in fact little is known about the reasons why "enriched" work sometimes leads to positive outcomes for workers and for their employing organizations. Even less is known about the relative effectiveness of various strategies for carrying out the redesign of work One reason

Power provisioning for a warehousesized computer,”

by Xiaobo Fan , Wolf-Dietrich Weber Luiz , André Barroso - ACM SIGARCH Computer Architecture News, , 2007
"... ABSTRACT Large-scale Internet services require a computing infrastructure that can be appropriately described as a warehouse-sized computing system. The cost of building datacenter facilities capable of delivering a given power capacity to such a computer can rival the recurring energy consumption ..."

in well-tuned applications there is a noticeable gap (7 -16%) between achieved and theoretical aggregate peak power usage at the cluster level (thousands of servers). The gap grows to almost 40% in whole datacenters. This headroom can be used to deploy additional compute equipment within the same power

The Hadoop Distributed File System

by Konstantin Shvachko, Hairong Kuang, Sanjay Radia, Robert Chansler
"... Abstract—The Hadoop Distributed File System (HDFS) is designed to store very large data sets reliably, and to stream those data sets at high bandwidth to user applications. In a large cluster, thousands of servers both host directly attached storage and execute user application tasks. By distributin ..."

High performance messaging on workstations: Illinois Fast Messages (FM) for Myrinet

by Scott Pakin, Mario Lauria, Andrew Chien - In Supercomputing , 1995
"... In most computer systems, software overhead dominates the cost of messaging, reducing delivered performance, especially for short messages. Efficient software messaging layers are needed to deliver the hardware performance to the application level and to support tightly-coupled workstation clusters. ..."

Utility functions in autonomic systems

by William E. Walsh, Gerald Tesauro, Jeffrey O. Kephart, Rajarshi Das - In Proceedings of the International Conference on Autonomic Computing , 2004
"... Utility functions provide a natural and advantageous framework for achieving self-optimization in distributed autonomic computing systems. We present a distributed architecture, implemented in a realistic prototype data center, that demonstrates how utility functions can enable a collection of auton ..."

of autonomic elements to continually optimize the use of computational resources in a dynamic, heterogeneous environment. Broadly, the architecture is a two-level structure of independent autonomic elements that supports flexibility, modularity, and self-management. Individual autonomic elements manage

Ceph: A scalable, highperformance distributed system,” in OSDI,

by Sage A Weil , Scott A Brandt , Ethan L Miller , Darrell D E Long , Carlos Maltzahn , 2006
"... Abstract We have developed Ceph, a distributed file system that provides excellent performance, reliability, and scalability. Ceph maximizes the separation between data and metadata management by replacing allocation tables with a pseudo-random data distribution function (CRUSH) designed for hetero ..."
Abstract - Cited by 275 (32 self) - Add to MetaCart
for heterogeneous and dynamic clusters of unreliable object storage devices (OSDs). We leverage device intelligence by distributing data replication, failure detection and recovery to semi-autonomous OSDs running a specialized local object file system. A dynamic distributed metadata cluster provides extremely

Implementing Global Memory Management in a Workstation Cluster

by Michael J. Feeley, William E. Morgan, Frederic H. Pighin, Anna R. Karlin, Henry M. Levy, Chandramohan A. Thekkath
"... Advances in network and processor technology have greatly changed the communication and computational power of local-area workstation clusters. However, operating systems still treat workstation clusters as a collection of loosely-connected processors, where each workstation acts as an autonomous an ..."
