“…In this context, the AM-PERE project [1] designed an ecosystem targeting the correctby-construction engineering of cyber-physical applications on parallel heterogeneous platforms. The ecosystem generates task-based parallel OpenMP applications from AMALTHEA [2] models, including mechanisms to offload computation to accelerators. This trait allows for defining function specializations based on conditions like the type of processor, e.g., CPU or GPU, hence fostering the deployment of multiple versions of the same application.…”

High-performance cyber-physical applications impose several requirements with respect to performance, functional correctness and non-functional aspects. Nowadays, the design of these systems usually follows a model-driven approach, where models generate executable applications, usually with an automated approach. As these applications might execute in different parallel environments, their behavior becomes very hard to predict, and making the verification of non-functional requirements complicated. In this regard, it is crucial to analyse and understand the impact that the mapping and scheduling of computation have on the real-time response of the applications. In fact, different strategies in these steps of the parallel orchestration may produce significantly different interference, leading to different timing behaviour.Tuning the application parameters and the system configuration proves to be one of the most fitting solutions. The design space can however be very cumbersome for a developer to test manually all combinations of application and system configurations. This paper presents a methodology and a toolset to profile, analyse, and configure the timing behaviour of highperformance cyber-physical applications and the target platforms. The methodology leverages on the possibility of generating a task dependency graph representing the parallel computation to evaluate, through measurements, different mapping configurations and select the one that minimizes response time.

Despite the high relevance of traceability in software processes, the activities of traceability creation and management are not always adequately supported in practice. The lack of integration between the tools adopted in the development processes is one of the main causes of such an ineffective management, where traceability relationships are still manually generated and maintained. In this paper we present an industrial experience we performed for improving the traceability management in a testing process performed in the Fiat Chrysler Automobiles company. In this context, we carried out a process for analyzing and identifying the main issues due to the ineffective traceability management and proposed a solution for addressing them.We designed and implemented a software architecture for integrating the existing application lifecycle management platform with the tools used in the process with the aim of automating the process execution and the traceability links management. The new architecture was validated by a case study that showed how the integration solution produced beneficial effects on quality attributes of the testing process. KEYWORDS automotive, industrial case study, software process improvement, tool integration, traceability management 1 INTRODUCTION Requirement traceability was defined by Gotel et al, 1 as the ability to describe and follow the life of a requirement, in both forward and backward directions.It is realized in practice by establishing relationships, usually defined trace links, between the requirements and one or more artifacts of the system. 2 Since then, this definition was extended, and nowadays, we talk more in general about software traceability for indicating the creation and the use of links (or connections) between different kinds of software artifacts such as requirements, models, source code, test cases, or test results. These connections are called trace links and connect in a bidirectional way a source artifact to a target artifact. The research community is devoting great efforts for addressing the topic of the traceability management that is the planning, the organization, and the coordination of all the activities related to traceability, including the creation, maintenance, and use of trace links. 3 Moreover, both software development standards and process assessment frameworks, such as ISO/IEC 15504, automotive SPICE, capability maturity model integration (CMMI), ISO 26262, and IEC 61508, suggest the companies to adopt traceability management solutions to guarantee Abbreviations: ALM, application lifecycle management; API, application programming interface; DSML, domain-specific modeling language; ECU, electronic control unit; FCA, Fiat Chrysler Automobiles; GUI, graphical user interface; ITL, incorrect traceability links; ITLRP, incorrect traceability links reduction percentage; MIL, model in the loop; MTL, missing traceability links; MTLRP, missing traceability links reduction percentage; RQ, research question; SP, speedup percentage; SPEM, software and system pr...
