MULTIPROCESSOR SOFT REAL TIME CPU RESOURCE MANAGER AND ITS VALIDATION WITH HYPERMEDIA APPLICATIONS

Multi-processor computers are becoming more ubiquitous as a technique for achieving better response times from calculation-heavy applications. Making efficient use of multiple processors to achieve a high degree of quality of service is a difficult problem. Simultaneous, multiple video streams are seen throughout the entertainment and news media services. Most of these services are proprietary and use very specific hardware and software. The Dynamic Soft Real Time server is a program that guarantees client applications soft real time deadlines. Soft deadlines are very useful in streaming media such as video streams. We investigate techniques to expand the Dynamic Soft Real Time server to make the most efficient use of CPU resources on a multi-processor machine. We developed an implementation of a Concurrent MPEG Player and multi-processor Dynamic Soft Real Time server that can enable an end user to navigate through multiple, simultaneous video streams while maintaining quality of service based on a user-selected policy. iii To my loving wife, Kate. iv Acknowledgments
