    Abstract:

    Scientists using workflows often have access to both High Performance Computing and High-Throughput Computing sites, but HPC sites’ architecture is less conducive to HTC paradigms. The choices of middleware and site can have drastic performance differences on different workflows. To explore these differences, we created tools to expand Makeflow and Work Queue’s capabilities. We then performed four speed of light tests, testing job dispatch rate, data delivery from the master to worker…

    Abstract:

    Domain-specific languages (DSLs) are frequently used in software engineering. In contrast to general-purpose languages, DSLs are designed for a special purpose in a particular domain. Due to volatile user requirements and new technologies DSLs, similar to the software systems they describe or produce, are subject to continuous evolution. This work explores existing research on DSL evolution to summarize, structure and analyze this area of research, and to identify trends and open issues. We c…

    Abstract:

    The growing adoption of small unmanned aircraft systems (sUAS) for tasks such as eCommerce, aerial surveillance, and environmental monitoring introduces the need for new safety mechanisms in an increasingly cluttered airspace. Safety assurance cases (SAC) provide a state-of-the-art solution for reasoning about system and software safety in numerous safety-critical domains. We propose a novel approach based on the idea of interlocking safety cases. The sUAS infrastructure safety case (iSAC) sp…

    Abstract:

    Remotely Piloted Aircraft Systems (RPAS) are an emerging application area for many industries including surveillance, agriculture monitoring, and vector-borne disease control. With drastically lower costs and increasing performance and autonomy, future application evolution will more than likely include the use of the RPAS swarms. Several largely successful experiments in recent years, using off the shelf small Unmanned Aircraft Systems (sUAS) have been conducted to address the long standing …

    Abstract:

    The full behavior of complex software systems often only emerges during operation. They thus need to be monitored at run time to check that they adhere to their requirements. Diverse runtime monitoring approaches have been developed in various domains and for different purposes. Their sheer number and heterogeneity, however, make it hard to find the right approach for a specific application or purpose. The aim of our research therefore was to develop a comparison framework for runtime monitor…
