The following topics are dealt with : computer architecture; data intensive and I/O computing; algorithm and application; P2P computing; service-oriented architecture; cluster computing; grid computing; cloud computing; performance evaluation; compilers and language; information retrieval; knowledge discovery; OS/resource management; wireless networks; and pervasive computing.
Based on analysis of various P2P architectures, the authors in this paper integrate semantic grid with super-peer P2P architecture. First of all, the authors introduce resources searching algorithm based on semantic cluster, and analyze the educational resources sharing mechanism & service system based on super-peer P2P, especially on the model of super-peer P2P. Then the authors focus on the...
In view of the lack of high-quality system development, this paper starts with the reuse and specification aspects respectively, puts forward the "intelligent platform For MIS" concept, helps system developers to use "natural" coding technology to develop platform-based program in a real sense, not only decreasing the developing difficulty, but also improving the maintainability.
Grid has evolved dramatically into the era of service-oriented grid, which facilitates building of large-scale systems in standard fashions, reusability of essential functions, and interoperability among components. However, grid resource allocation is still a challenging problem for which a grid scheduler has to be operating in a dynamic and uncertain environment. Conventional scheduling algorithms...
In order to realize the purpose of precise profit management, resolve data isolated phenomena, utilize all kinds of university resources efficiently, and improve the quality and efficiency of university management, a new and feasible URP (university resource planning) project based on digital university is proposed in this paper, which is established based on the ideology of digital, apply the ideas...
Service orientation is a promising paradigm for business architectures. Implementing a service-oriented architecture (SOA) promises increasing flexibility as well as agility and decreasing development and maintenance costs of IT landscapes. Simultaneously with these advantages, the implementation of an SOA entails some inherent challenges. The flexible orchestration of services increases the complexity...
Service concept is evolving as a broad idea recurrently discussed in recent years as it originates from many disciplines such as marketing, operations and computer science. Despite this interdisciplinary nature of service concept, existing methodologies for building service-oriented systems provide limited support to include a complete coverage of various engineering phases for a unified development...
Nowadays, grid computing is moving from sharing computing power and storage resources to sharing business resources, including any abstract business entities and resources. The new trend brings a big challenge, since these universal business resources typically do not belong to the same level. Describing them is already difficult; describing them in a unified way is even more difficult. Business process...
The traditional Web model can't meet the requirement of file resource management under Internet environment for reasons of Web server bottleneck, resource replication management, resource discovery and network bandwidth problems. Grid technology provides an efficient method for distributed resources management. This paper introduces architecture of educational resources grid (ERG) and analyzes the...
The allocation of tasks can be seen as a success-critical management activity in distributed development projects. However, such task allocation is still one of the major challenges in global software development due to an insufficient understanding of the criteria that influence task allocation decisions. This article presents a qualitative study aimed at identifying and understanding such criteria...
The success of all kinds of commercial applications or scientific computing running on heterogeneous computing environments is absolutely dependent on the availability and reliability of resources composing the environment. In order to support the major Monitor/Analyze/Plan/Execute management activities for resources, Web service based WS-Management rather than SNMP is drawing more and more attention...
This paper describes the distributed resource management for QoS driven for CAD-Grid integrated system. In this work, system actualization mode, architecture and function module are discussed in building a distributed QoS driven for CAD-Grid system. An emphasis has been placed on making the tools interactive, in an effort to create a user friendly environment. The goal is to provide an efficient and...
With the converging of grid computing and Web service, grid has extended its territory from traditional computing grid to service-oriented grid, which is aiming to realize coordinated resource sharing and problem solving through service selection and composition. Therefore, selecting credible services for applications becomes a key issue in grid environment. Current research on trust inherits the...
As the key character of grid is the good service quality, the study of QoS (quality of services) becomes more and more important. And SLA (service level agreement) can really guarantee the QoS. Although SLA has been a topic in the field of telecom for many years, the researches of it in the grid are still not perfect, especially in the emerging grid economy field. In this paper, we propose a SLA control...
In this paper, we propose a technique called LACT for automatically categorizing software systems in open-source repositories. LACT is based on latent Dirichlet Allocation, an information retrieval method which is used to index and analyze source code documents as mixtures of probabilistic topics. For an initial evaluation, we performed two studies. In the first study, LACT was compared against an...
Recent work on component-based software design has proved the need of resource-accurate development of embedded software. In the more specific cases of mobile systems, the developer also needs tools to facilitate the adaptation of functionalities to resources (lack of memory or bandwidth, etc.), and also to evaluate the performance w.r.t. the resource issues. As we want to design and develop at the...
Tiny devices, smart objects, home gateways, sensor networks, have become an integral part of our everyday life and of our socio-economic ecosystem. However their large number, their distribution and their volatility and heterogeneity make their management fiendishly complex. Traditional management systems, that are mainly ad-hoc or centralized, reach their limits in such complex management contexts...
To expand the use of distributed computer infrastructures as well as facilitate grid interoperability, OGSA has developed standards and specifications that address a range of scenarios, including high-throughput computing, federated data management, and service mobility.
This study's objective is to solve mining knowledge issue from different sources of distributed, formatted or unformatted data with diverse data semantics. The issue is formulated as data mining in knowledge grid. In particular, this paper presented a DM-GRID (data mining in grid) model based on software architecture of a novel infrastructure for distributed and high-performance data mining in knowledge...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
