We present and compare a variety of parallelization approaches for a real-world case study on modern parallel and distributed computer architectures. Our case study is a production-quality, time-intensive algorithm for medical image reconstruction used in computer tomography (PET). We parallelize this algorithm for the main kinds of contemporary parallel(More)
Massively Multi-player Online Games (MMOG) are characterized by intensive interactions between many simultaneous users and real-time demands on Quality of Service (QoS). Other examples of similar, real-time online interactive applications include various virtual environments, as well as multi-pupil e-learning and simulation-based training courses. A highly(More)
We demonstrate that for modern medical imaging applications, parallel implementations on traditional parallel architectures (clusters and multiprocessor servers) can be outperformed, both in terms of speed and cost-effectiveness, by new implementations on next-generation architectures like GPUs (Graphics Processing Units). Although, compared to clusters and(More)
We consider a challenging class of highly interactive virtual environments, also known as Real-Time Online Interactive Applications (ROIA). Popular examples of ROIA include multi-player online computer games, e-learning and training based on real-time simulations, and other challenging applications. ROIA combine high demands on scalability and real-time(More)
This paper focuses on providing an overview of the research challenges that have been identified toward the end of the S-Cube network in the area of service engineering. These challenges concern the need for agility and dynamicity of the development process for service-based applications, the importance of focusing on proper approaches to support migration(More)
We consider a challenging class of highly interactive virtual environments, also known as Real-Time Online Interactive Applications (ROIA). Popular examples of ROIA include multi-player online computer games, e-learning and training applications based on real-time simulations, among others. An emerging enhancement for ROIA is the use of mobile devices for(More)
