Paper Abstract

Complex multimedia applications have diverse resource and timing requirements. A platform for building such programs therefore should supply the developer with mechanisms for managing concurrency, communication, and real-time constraints but should remain flexible with regard to scheduling policies and interaction models. We have developed such a platform consisting of a user-level threads package and operating system extensions. The threads package offers a message-based threading model uniformly integrating synchronous and asynchronous communication, inter-thread synchronization, and signal handling as well as real-time functionality and application-specific scheduling. To support this user-space flexibility an upcall mechanism links the user-level scheduler to the kernel.
