The complexity of high-end computing has been increasing rapidly following the exponential increase in processing speed of the novel electronic digital technologies. Subsequently, the software development productivity has been attracting higher attention by the professional community because of its increasing importance for the development of complex software systems and applications. At the same time, component-based technologies have emerged as a modern and promising alternative with a clear potential to improve significantly the productivity of software development, particularly for extreme-scale computing. However, the lack of longer-term experience and the increasing complexity of the target systems demand much more research results in the field. In particular, the search for the most appropriate component model and corresponding programming environments is of high interest and importance. The higher level of complexity involves a wider range of requirements and resources which demand dedicated support for dynamic properties and flexibility that could be provided in an elegant way by adopting the component-based methodology for software development.
