“…The third graph in each figure indicates the additional improvements in end-to-end latencies accrued as a result of leveraging backend optimization frameworks, such as PAM [10]. PAM is a deployment-time technique that fuses a set of components collocated in a container to reduce memory footprint and latency between service invocations.…”

“…We show how the end-to-end latency results after applying our algorithm achieves considerable improvement over the existing state-of-the-art. Moreover, we also demonstrate a beneficial side effect of our solution by discussing how the algorithm can be combined with additional backend optimization frameworks like the Physical Assembly Mapper (PAM) [10].…”

“…First, by realizing the heuristicbased algorithm as an automated model transformation process, it can be seamlessly reapplied and reused during the iterative DRE system development process. Second, the configurations generated by our algorithm can be leveraged by additional backend optimization tools and techniques, such as the Physical Assembly Mapper (PAM) [10] which reduces time and space overheads by merging collocated components at system deployment-time.…”

Abstract. The quality of a software architecture for component 1 -based distributed systems is defined not just by its source code but also by other systemic artifacts, such as the assembly, deployment, and configuration of the application components and their component middleware. In the context of distributed, real-time, and embedded (DRE) component-based systems, bin packing algorithms and schedulability analysis have been used to make deployment and configuration decisions. However, these algorithms make only coarse-grained node assignments but do not indicate how components are allocated to different middleware containers on the node, which are known to impact runtime system performance and resource consumption. This paper presents a model transformation-based algorithm that combines user-specified quality of service (QoS) requirements with the node assignments to provide a finer level of granularity and precision in the deployment and configuration decisions. A beneficial side effect of our work lies in how these decisions can be leveraged by additional backend performance optimization techniques. We evaluate our approach and compare it against the existing state-of-the-art in the context of a representative DRE system.

This paper investigates the application of domainspecific languages in product line engineering (PLE). We start by analyzing the limits of expressivity of feature models. Feature models correspond to context-free grammars without recursion, which prevents the expression of multiple instances and references. We then show how domain-specific languages (DSLs) can serve as a middle ground between feature modeling and programming. They can be used in cases where feature models are too limited, while keeping the separation between problem space and solution space provided by feature models. We then categorize useful combinations between configuration with feature model and construction with DSLs and provide an integration of DSLs into the conceptual framework of PLE. Finally we show how use of a consistent, unified formalism for models, code, and configuration can yield important benefits for managing variability and traceability. We illustrate the concepts with several examples from industrial case studies.

A large proportion of the requirements on embedded real-time systems stems from the extra-functional dimensions of time and space determinism, dependability, safety and security, and it is addressed at the software level. The adoption of a sound software architecture provides crucial aid in conveniently apportioning the relevant development concerns. This paper takes a software-centered interpretation of the ISO 42010 notion of architecture, enhancing it with a component model that attributes separate concerns to distinct design views. The component boundary becomes the border between functional and extra-functional concerns. The latter are treated as decorations placed on the outside of components, satisfied by implementation artifacts separate from and composable with the implementation of the component internals. The approach was evaluated by industrial users from several domains, with remarkably positive results
