The overall goal of the SRM effort is to develop techniques for coordinated but decentralized control of system resources in distributed systems. These techniques will provide integrated management of 1 multiple system resources, including the processing, communication, and data storage components of the system 2 multiple system objectives i.e., level-of-service preferences, such as timeliness, precision, and correctness 3 multiple activities e.g., applications or tasks competing for resources 4 multiple nodes in a distributed system and 5 multiple techniques and mechanisms for meeting objectives. The resource management system will allocate distributed system resources to multiple competing activities in such a way that objectives as a whole can be satisfied to the highest degree possible. The goals of the research for this effort were to 1 develop abstractions that model common system objectives such as performance, functionality, availability, precision, and security 2 develop abstractions that model system components e.g., processing, communication, and storage subsystems and higher level services that are based on these components e.g., distributed database systems or distributed file systems 3 develop abstractions and mechanisms that provide integrated control across the objectives and components of a distributed system and 4 show the validity of the abstractions by applying them to one or more sample scenarios and implementing a proof-of-concept demonstration application.
