    To support distributed parallel computing across asynchronous transfer mode networks, the interplay between communications software and the network architecture is critical. In particular, we can improve communication performance significantly by efficiently designing collective communication operations, such as multicast and reduction.<> View full abstract»

    Parallel processing facilitates the real-time implementation of an end-effector velocity controller for elastic robotic manipulators. The approach has potential application in teleoperation. We have developed an algorithm that controls end-effector velocity of large robotic manipulators whose size-to-weight ratio renders them structurally flexible. The controller takes: desired end-effector veloci... View full abstract»

    This paper concerns the problem of scheduling instability, where reducing the duration of one or more tasks delays the starting time of another task. This can make it difficult or impossible to guarantee real-time deadlines. Unfortunately, simulating schedules with all possible variations in the durations of all tasks is in most cases an intractable problem. Therefore, task dispatching must be pro... View full abstract»

    Until now, little research has been done on methods to combine the seemingly incompatible paradigms of hard and soft real-time systems. To this end, we have developed Dedos, a dependable distributed operating system. The driving forces behind the project are twofold: to meet the demand for dependable distributed control systems, especially in the area of embedded systems and industrial control; an...

    Investigations that analyze the time an operating system takes to schedule, interrupt and "context-switch" to another process or job have helped developers produce highly optimized and tuned operating systems that can provide more than 99% sustained processor use for most uniprocessor applications. However, when these operating systems are installed on CPUs that are interconnected with a low-laten... View full abstract»

    The Development Framework translates application-specific system specifications into parallel, hard real-time implementations, using methods that are both familiar to developers and optimal for the application. The Development Framework approach applies CASE tools-as well as several new tools-to the development of distributed systems, so designers can concentrate on the control-engineering aspects...
