    Performance evaluation of a distributed integrative architecture for robotics

    The eld of robotics employs a vast amount of coupled sub-systems. These need to interact cooperatively and concurrently in order to yield the desired results. Some hybrid algorithms also require intensive cooperative interactions internally. The architecture proposed lends it- self amenable to problem domains that require rigorous calculations that are usually impeded by the capacity of a single machine, and incompatibility issues between software computing elements. Implementations are abstracted away from the physical hardware for ease of de- velopment and competition in simulation leagues. Monolithic developments are complex, and the desire for decoupled architectures arises. Decoupling also lowers the threshold for using distributed and parallel resources. The ability to re-use and re-combine components on de- mand, therefore is essential, while maintaining the necessary degree of interaction. For this reason we propose to build software components on top of a Service Oriented Architecture (SOA) using Web Services. An additional bene t is platform independence regarding both the operating system and the implementation language. The robot soccer platform as well as the associated simulation leagues are the target domain for the development. Furthermore are machine vision and remote process control related portions of the architecture currently in development and testing for industrial environments. We provide numerical data based on the Python frameworks ZSI and SOAPpy undermining the suitability of this approach for the eld of robotics. Response times of signi cantly less than 50 ms even for fully interpreted, dynamic languages provides hard information showing the feasibility of Web Services based SOAs even in time critical robotic applications

    A look at cloud architecture interoperability through standards

    Enabling cloud infrastructures to evolve into a transparent platform while preserving integrity raises interoperability issues. How components are connected needs to be addressed. Interoperability requires standard data models and communication encoding technologies compatible with the existing Internet infrastructure. To reduce vendor lock-in situations, cloud computing must implement universal strategies regarding standards, interoperability and portability. Open standards are of critical importance and need to be embedded into interoperability solutions. Interoperability is determined at the data level as well as the service level. Corresponding modelling standards and integration solutions shall be analysed

    Domain Objects and Microservices for Systems Development: a roadmap

    Full text link
    This paper discusses a roadmap to investigate Domain Objects being an adequate formalism to capture the peculiarity of microservice architecture, and to support Software development since the early stages. It provides a survey of both Microservices and Domain Objects, and it discusses plans and reflections on how to investigate whether a modeling approach suited to adaptable service-based components can also be applied with success to the microservice scenario

    INTEGRATION VERSUS DEDICATION IN ROMANIAN MANAGEMENT SUPPORT SYSTEMS

    The technologies supporting future business must be intuitive from a user standpoint, flexible from design standpoint and highly productive. As an answer to many requirements, analysts recommend the inclusion of SOA and ESB in the IT management strategies, since these tend to become mainstream, overcoming their abstract vision status in the last decade. In this paper, we provide a study regarding the attitude of companies from north-western Romania with respect to this transition and the SOA&ESB models. Our analysis targets attributes such as: level of understanding, knowledge and concern in adopting such technologies, the management involvement in the company IT strategy, the added value of the new technologies and risk factors for the migration towards an SOA&ESB architecture.integration,enterprise applications,web applications,SOA,ESB,framework

    An investigation of the performance portability of OpenCL

    Get PDF
    This paper reports on the development of an MPI/OpenCL implementation of LU, an application-level benchmark from the NAS Parallel Benchmark Suite. An account of the design decisions addressed during the development of this code is presented, demonstrating the importance of memory arrangement and work-item/work-group distribution strategies when applications are deployed on different device types. The resulting platform-agnostic, single source application is benchmarked on a number of different architectures, and is shown to be 1.3ā€“1.5Ɨ slower than native FORTRAN 77 or CUDA implementations on a single node and 1.3ā€“3.1Ɨ slower on multiple nodes. We also explore the potential performance gains of OpenCLā€™s device fissioning capability, demonstrating up to a 3Ɨ speed-up over our original OpenCL implementation
