This paper discussed the key technologies for building a Geospatial Information Grid service workflow and describes the design and implementation of a Grid GIS service integration and hybrid invocation prototype framework: the MapGIS Grid Workflow Framework (MGWF). First, we discussed the WSRF based GIS function encapsulation details for legacy GIS system. Then we researched on the Grid GIS services...
Improved resource utilization and fault tolerance of large-scale HPC systems can be achieved through fine-grained, intelligent, and dynamic resource (re)allocation. We explore components and enabling technologies applicable to creating a system to provide this capability: specifically 1) Scalable fine-grained monitoring and analysis to inform resource allocation decisions, 2) Virtualization to enable...
For complicated Software-Intensive System, it is always hard to guarantee the reliability and safety of software. Effective methods for detecting faults and isolating software fault from hardware fault are desiderated especially. In order to detect and isolate fault in SIS, a method called runtime software monitoring is studied, and a new kind of runtime software monitoring system(RSMS) is constructed...
Policies have been identified as one possible way to specify to management systems the operational constraints of a system or systems being managed. Such policies, often characterized as event-triggered condition actions rules, are frequently defined via policy languages and or user interface tools in order to simplify their expression and understanding by system administrators. The underlying assumption...
We present an automated framework for the inference of behavioral models from the execution traces of a Web-based business application (WBA). The model inference framework consists of a formal approach to infer automata models from traces of WBA's and an advanced prototype tool set implemented around the data mining engine Weka, the model checker SPIN, the formal language manipulation framework ANTLR...
Web applications have become very popular today in a variety of domains. Given the varied nature of client-side environments and browser configurations, it is difficult to completely test or debug the client-side code of Web applications in-house. There are tools that facilitate functional testing on various browsers, but they cannot mimic all of the possible client-side environments. In modern Web...
This paper introduced a monitoring architecture that is highly scalable and suitable for practical use in distributed environments. We also introduced two applications as illustrative embodiments of our concept and monitoring system. For better scalability and practicality, we are planning further developments on both monitoring system itself and applications.
In the present work we describe the development of a condition based maintenance platform especially shaped for a network of maintenance companies operating on the same assets. The expert system developed in this study, holds the skills of a team of experts who thoroughly know both the monitored system and its maintenance. The company and the network of expertise available were also considered. Indeed,...
A key benefit of utility data centers and cloud computing infrastructure is the level of consolidation they can offer to arbitrary guest applications, and the substantial saving in operational costs and resources that can be derived in the process. However, significant challenges remain before it becomes possible to effectively and at low cost manage virtualized systems, particularly in the face of...
This paper describes a benchmarking workload model for business process execution language (BPEL) engines for Web services. The proposed model is based on simulation of real world traffic conditions by defining a set of requirements which best characterize the end-users. The performance characteristics are evaluated on top of collected measurements such as success/fail rate, response times or round-trip...
