Abstract :
To support thread-based real-time computing, we propose a new multithreading architecture which includes virtual threads and scheduling event upcalls. We have implemented this architecture in the ARX real-time operating system. Our experimental results show that our user-level thread schemes outperform kernel threads found in important commercial operating systems without compromising the benefits of user-level threads
