并行构件技术作为并行软件工程的主要内容之一,对提高并行计算软件的生产率具有重要意义,也是并行软件工程的重要研究内容。并行构件技术研究现状包含并行构件模型、并行构件体系结构规范、并行构件框架3个方面。并行构件、接口、框架的定义和实现是区分不同并行构件体系结构规范的主要标准。如何在实现并行构件复用性的同时提高并行构件组成的应用系统性能,是这些技术发展的共同思想。单构件多数据、多构件多数据编程模型、多语言互操作技术、并行远程方法调用、MxN问题的解决方法、不同模型构件间的互操作都是并行构件领域的研究成果。并行构件技术的发展方向是开展对多语言互操作、性能预测、自适应构件、构件模型的互操作、多核硬件上的并行构件体系结构技术的研究。 相似文献

Semantic interoperability is a crucial element to make building information models understandable and model data sharable across multiple design disciplines and heterogeneous computer systems. This paper presents a new approach and its software implementation for the development of building design objects with semantics of interoperable information to support semantic interoperability in building designs. The novelty of the approach includes its incorporation of building design domain ontology, object-based CAD information modeling, and interoperability standard to make building information models and model data semantically interoperable. A set of methods are proposed to address the issues of object-based building information representation compliant with the Industrial Foundation Classes (IFC); extension of IFC models with the supplementary information; and semantic annotation of the interoperable and extensible information sets. The prototype implementation of these methods provides a set of Web-enabled software tools for effectively generating, managing, and reusing the semantically interoperable building objects in design applications of architectural CAD, structural analysis, and building code conformance checking. 相似文献

软件组件的互操作性和透明性 总被引:2,自引:0,他引:2
互操作性和透明性独立于系统功能。分布式系统结构实现互操作性和透明性非常复杂,需要深入的软件工程知识、系统软件体系结构和新的系统互操作性观点。尽管使用技术可以获得特定情况下的互操作性,但不能解决一般意义下的透明互操作性问题。对分布式系统的互操作性和透明性问题进行了深入地分析与阐述,并探究了互操作性与软件体系结构的关系,着重讨论了交叉领域的互操作性要求。相信与软件体系结构结合起来的互操作性和透明性的实现将对大规模、复杂的分布式系统产生深远的影响。 相似文献

Interoperability of heterogeneous applications is defined as the ability for multiple software applications written in different programming languages running on different platforms with different operating systems to communicate and interact with one another over different computer networks. The emerging middleware technologies, including CORBA, COM/DCOM, and Enterprise JavaBeans offer an industrial defacto standard communication infrastructure to support the interoperability of heterogeneous applications in components. However, the implementation of a component suffers from high interaction complexities in the component that seriously degrades the application independence. Software components should be built to be independent of the context in which they are used, allowing them to be reused in many different computing environments. In this paper, we are presenting an adapter to isolate, encapsulate, and manage a component's interactions outside the component. The dynamic interface binding was designed to allow an adapter to examine the signature of the requested services at runtime such as operation names, parameters orders, parameters types, and parameters sizes. The interfaces of interconnecting components are bound at runtime. In addition, the interface language mapping allows an interface in a specific programming language to be automatically generated from an IDL interface. The use of adapters increases the reusability of components and also simplifies the integration of the components to an application. 相似文献

One of the main open issues in the development of applications for sensor network management is the definition of interoperability mechanisms among the several monitoring systems and heterogeneous data. Interesting researches related to integration techniques have taken place, they are primary based on the adoption of sharing data mechanisms. In the last years, the Service-Oriented Architecture (SOA) approach has become predominant in many sensor network projects as it enables the cooperation and interoperability of different sensor platforms at an higher level of abstraction. In this paper we propose a novel architecture for the interoperability of sensor networks, which is based on web services technologies and on a common data model enriched with semantic concepts and annotations. The proposed architecture allows the development of complex decision support system applications by integration of heterogeneous data, accessible through services, according to standard data format and standard protocols. 相似文献
