In order for a Future Internet architecture to be globally deployed, it must ensure that existing applications will continue to operate efficiently on top of it. As part of the Publish Subscribe Internet Routing Paradigm (PSIRP) project, we have explored various options for making endpoint centric applications based on the Sockets Application Programming Interface (API) compatible with the info...

Simulation is inevitable for dimensioning interconnection networks for parallel computers. In this study, we present the application of a parallel eventdriven simulator for k-ary 2-cube wormhole-routing interconnection networks running on the Intel Paragon and discuss simulator speedup behavior and influence of the operation modes of the simulated network (synchronous, asynchronous, and mixed m...

The paper develops the adaptive dynamic programming toolbox (ADPT), which is a MATLAB-based software package and computationally solves optimal control problems for continuous-time control-affine systems. ADPT produces approximate feedback controls by employing technique solving Hamilton–Jacobi–Bellman equation approximately. A novel implementation method derived to optimize memory consumption ...

Typical processes controlled by hard real-time computer systems undergo several, mutually exclusive modes of operation. By deterministically switching among a number of static schedules, a pre run-time scheduled system is able to adapt to changing environmental situations. This paper presents concepts for speci cation of mode changes, construction of static schedules for modes and transitions, ...

The execution of distributed applications involving mobile terminals and fixed servers connected by wireless links raises the need for handling network disconnections, both involuntary during unexpected connection breakdowns, and voluntary when the user wants to save money and energy. In this paper, we investigate how standard CORBA mechanisms (Objects By Value and Portable Interceptors) can be...

A common assumption for scheduling mixedcriticality systems is the degradation of less critical tasks when the system is in the emergency mode; which is entered when critical tasks overrun their expected WCET. In the meanwhile, common safety standards enforce strict safety requirements on all criticality levels. However, the impact of degrading less critical tasks on the overall system safety i...

Multi-GPUs appear as an attractive platform to speed up data-parallel GPGPU computation. The idea of split-and-merge execution has been introduced to accelerate the parallelism of multiple GPUs even further. However, it has not been explored before how to exploit such an idea for real-time multi-GPU systems properly. This paper presents an open-source real-time multi-GPU scheduling framework, c...

This paper describes the implementation of a featurebased visual tracking algorithm on a SIMD MasPar MP-1 and the mixed-mode PASM prototype. The sequential algorithm is introduced and a parallel version of the algorithm is described. Aspects of the mapping of this algorithm onto both machines are presented. Real image data was used to obtain timing results for all experiments. For the SIMD impl...
