The current approaches for regression test selection of embedded programs are usually based on data- and control-dependency analyses, often augmented with human reasoning. Existing techniques do not take into account additional execution dependencies ...

A prototype Taskspaces framework for grid computing of scientific computing problems that require intertask communication is presented. The Taskspaces framework is characterized by three major design choices: decentralization provided by an underlying ...

We present an optimal solution to the problem of allocating communicating periodic tasks to heterogeneous processing nodes (PNs) in a distributed real-time system. The solution is optimal in the sense of minimizing the maximum normalized task response ...

CARTS is a set of system services targeted to real time distributed systems and spanning a variety of architectures. CARTS was designed to support rapid application code generation through generic user interfaces, to facilitate incremental system ...

Clusters, or networks, of workstations (NOW) have proven their value for certain classes of applications, those that can be efficiently parallelized with coarse granularity requiring relatively little intertask communication. However clusters of ...

The multiprocessor scheduling problem is the problem of scheduling the tasks of aprecedence constrained task graph (representing a parallel program) onto the processorsof a multiprocessor in a way that minimizes the completion time. Since this problem ...

Three main factors influence the response time of real-time systems: (1) the scheduling of computing resources, (2) inter-task communication and queueing, (3) service times experienced by tasks once the resource is available. This dissertation addresses ...

Stochastic rendezvous networks (SRVN) are performance models for multitasking parallel software with intertask communication via rendezvous (RV). The paper describes an approximation for the arrival instant probabilities for a class of simple client/...

A demonstration-quality graphics-assisted debugger is developed for intertask communication in Ada. Based on the static task-specification diagrams of G. Booch, the debugger animates the activity of a collection of communicating tasks, and it runs on a ...

Distributed data acquisition and control systems are envisioned as the solution to objectives sought for a long time: reliable online systems which degrade gracefully. Critical applications however require a great deal of communication of both commands ...
