The parallel programming community has long recognized the need for a simple programming environment offering interprocess communication between heterogeneous systems. As the Parallel Virtual Machine environment, PVM, has emerged to meet this goal, an increasing number of educational institutions are choosing PVM to support their teaching of parallel and distributed computing using networks of workstations. However, it is often the nature of PVM's design and implementation that can severely limit its success in a teaching environment. This paper first motivates and then describes improvements to the PVM environment which increase both robustness and efficiency in an educational setting.
In the presence of side-constraints and optimization criteria, round robin tournament problems are hard combinatorial problems, commonly tackled with tree search and branch-and-bound optimization. Recent results indic...

In this paper we present our experiences from a decade of plug-in development in the jABC framework, that is characterized by rigorous application of simplicity principles in two dimensions. First, the scope of the plug-in development is clearly defined: The jABC readily provides a sophisticated graphical user interface, which has been tailored to working with all kinds of directed graphs. Within this scope, plug-in development can deliberately focus on the actual functionality, like providing semantics to graphs, without having to deal with tedious but semantically irrelevant issues like user interfaces. Second, plug-in functionality can be itself conveniently modeled as a workflow within the jABC. We illustrate our approach by means of two mature plug-ins: Genesys, a plug-in that adds arbitrary code generator functionality to the jABC, and PROPHETS, a plug-in that eases user-level definition of workflows by completing model sketches by means of synthesis capabilities, so that they become complete and executable. We summarize our experience so far and derive general design principles for “lightweight plug-in development”, that we are going to realize in the next generation of the jABC, which will be implemented itself as a collection of Eclipse plug-ins.
Using Genetic programming difficult optimization problems can be solved, even if the candidate solutions are complex objects. In such cases, it is a costly procedure to correct or replace the invalid individuals that ...

The paper deals with the development of the method of activity and the realization of the intelligent agent (IA) for semantic analysis of the natural language software requirements. This IA performs the analysis of the requirements, determines the number and percentage of missing indicators for determining the metrics of complexity and quality of software, displays which indicators are missing for each metric, and also forms the real ontology of the domain "Software Engineering" (part "Quality and complexity of software. Metric analysis"). During an experiment, which is conducted with the help of the realized IA, the semantic analysis of requirements for the Internet of Things (IoT)-system was performed. Such analysis provides an increase of the volume and ensures of the sufficiency of metric information in the software requirements, which, in turn, provides an improvement in the quality of the software of IoT-system.

We present a case study that illustrates the power of active learning for enabling the automated quality assurance of complex and distributed evolving systems. We illustrate how the development of the OCS, Springer Verlag's Online Conference System, is supported by continuous learning-based testing, that by its nature maintains the synchrony of the running application and the learned (test) model. The evolution of the test model clearly indicates which portions of the system remain stable and which are altered. Thus our approach includes classical regression testing and feature interaction detection. We show concretely how model checking, automata learning, and quantitative analysis concur with the holistic quality assurance of this product.
