distributedapplications are a necessity in most central application sectors of the contemporary information society, including e-commerce, e-banking, e-learning, e-health, telecommunication and transportation. This results from a tremendous growth of the role that the Internet plays in business, administration and our everyday activities. This trend is going to be even further expanded in the context of advances in broadband wireless communication. New Developments in distributedapplications and Interoperable Systems focuses on the techniques available or under development with the goal to ease the burden of constructing reliable and maintainable interoperable information systems providing services in the global communicating environment. The topics covered in this book include: Context-aware applications; Integration and interoperability of distributed systems; Software architectures and services for open distributed systems; Management, security and quality of service issues in distributed systems; Software agents and mobility; Internet and other related problem areas. The book contains the proceedings of the Third international Working conference on distributedapplications and Interoperable Systems (DAIS'2001), which was held in September 2001 in Kraków, Poland, and sponsored by the international Federation on Information processing (IFIP). The conference program presents the state of the art in research concerning distributed and interoperable systems. This is a topical research area where much activity is currently in progress. Interesting new aspects and innovative contributions are still arising regularly. The DAIS series of conferences is one of the main international forums where these important findings are reported.

distributed Stream processing (DSP) focuses on the near real-time processing of large streams of unbounded data. To increase processing capacities, DSP systems are able to dynamically scale across a cluster of commodity nodes, ensuring a good Quality of Service despite variable workloads. However, selecting scaleout configurations which maximize resource utilization remains a challenge. This is especially true in environments where workloads change over time and node failures are all but inevitable. Furthermore, configuration parameters such as memory allocation and check-pointing intervals impact performance and resource usage as well. Sub-optimal configurations easily lead to high operational costs, poor performance, or unacceptable loss of service. In this paper, we present Demeter, a method for dynamically optimizing key DSP system configuration parameters for resource efficiency. Demeter uses Time Series Forecasting to predict future workloads and Multi-Objective Bayesian Optimization to model runtime behaviors in relation to parameter settings and workload rates. Together, these techniques allow us to determine whether or not enough is known about the predicted workload rate to proactively initiate short-lived parallel profiling runs for data gathering. Once trained, the models guide the adjustment of multiple, potentially dependent system configuration parameters ensuring optimized performance and resource usage in response to changing workload rates. Our experiments on a commodity cluster using Apache Flink demonstrate that Demeter significantly improves the operational efficiency of long-running benchmark jobs.

Vector digital signal processors (DSPs) offer a good performance to power consumption ratio. Therefore, they are suitable for mobile devices in software defined radio applications. These vector DSPs require input algorithms with vector operations. The performance of vectorized algorithms to a great extent depends on the distribution of data on vector elements. Traditional algorithms for vectorization focus on the extraction of parallelism from a program;we propose an analysis tool that focuses on the selection of an efficient dynamic data mapping for vector DSPs. We transferred Garcia's communication parallelism graph (Garcia et al., IEEE Trans parallel Distrib Syst 12: 416-431, 2001) for distributed memory multiprocessor systems to vector DSPs. By alternating the representation of two-dimensional data distributions and the cost models, we are able to determine a dynamic mapping of data on vector elements on the Embedded Vector Processor (EVP) (van Berkel et al., Proceedings of the 2004 software-defined radio technical conference SDR'04, 2004). Additionally, we propose a new efficient algorithm for processing the graph representation that operates in two steps. We demonstrate the capabilities of our tool by describing the vectorization of some MIMO OFDM algorithms.
