Colloquium - Nutt

Dynamically Negotiated Resource Management
Department of Computer Science
9/10/1998
3:45pm-4:45pm

In contemporary computers, and networks of computers, various application domains are making increasing soft real-time demands on the way they would like to use the system's resources. A brute force technique for supporting applications in this type of domain demands excessive system resources, even though the actual resource requirements by different parts of the application vary according to the work it is doing at any particular time. A more sophisticated approach is to provide applications with the ability to dynamically adjust resource requirements according to their current needs as well as the availability of system resources.

This talk describes a set of principles for designing systems to provide support for soft real-time applications using dynamic negotiation. Next, the execution level abstraction is introduced as a specific mechanism for implementing the principles. The utility of the principles and the execution level abstraction is then shown in the design of three resource managers that facilitate dynamic application adaptation: Gryphon, EPA/RT-PCIP, and the DQM architectures.

Refreshments will be served immediately before the talk at 3:30pm.
