A large number of storage resources and computational power are combined to form a data grid network to deal with massive data of scientific experiments. Data replication generates huge data which are distributed in wide-area for researches around the globe. The files of grid environments can be modified by grid users might bring a critical problem of maintaining data consistency among the several replicas distributed in different machines. For that reason how to maintain the consistency of those files is a great challenge. In this paper, we propose a Oneway Replica Consistency model in data grid environments, which is used for consistency maintenance issue. Furthermore, we anticipate striking a balance between improving data access performance and replica consistency in data grids. This work can find out the more efficient ways of utilizing storage space is an important point.","PeriodicalId":370753,"journal":{"name":"The 2nd IEEE Asia-Pacific Service Computing Conference (APSCC 2007)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125331799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By deeply analyzing the characteristics of traditional packet forwarding in end host, this paper proposes a high performance multicast scheme, in which a NIC-based multicast mechanism is used to send multiple replicas of a ALM packet to different destinations with less CPU intermediation compared to the traditional host- based multicast scheme. By adopting the NIC-based multicast scheme, the CPU overhead and the number of times data packets are copied from host memory to NIC buffer are reduced. Theoretical analysis indicates that the new scheme can notably decrease the multicast delay and enhance the service capability of ALM proxies. We have modified the NIC driver and added some corresponding APIs to network protocol stack in order to implement the proposed scheme. Experimental results illustrate that the NIC-based multicast scheme can greatly improve forwarding rate for ALM.","PeriodicalId":370753,"journal":{"name":"The 2nd IEEE Asia-Pacific Service Computing Conference (APSCC 2007)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124894348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The computing power and storage space of grids is collected from heterogeneous or homogeneous resources in order to support complicated computing problems. Job scheduling in computing grid is a very important problem. Current scientific applications become more complex and need huge computing power and storage space. It may take a very long time to complete a complicated job. However, to utilize grids, we need an efficient job scheduling algorithm to assign jobs to resources in grids. In this paper, we propose a Balanced Ant Colony Optimization (BACO) algorithm for job scheduling in the Grid environment. There are two schemes introduced in this paper regarding local and global pheromone update. The main contributions of our work are to balance the entire system load and minimize the makespan of a given set of jobs. Compared with the other proposed algorithms, BACO can outperform them according to the experimental results.","PeriodicalId":370753,"journal":{"name":"The 2nd IEEE Asia-Pacific Service Computing Conference (APSCC 2007)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126615585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present a layered elimination optimization (LEO) which is an algorithm independent technique aims to detect maximum amount of redundant readers could be safely removed or turned off with preserving original RFID network coverage. A significant improvement of the LEO scheme is that number of \"write-to-tag\" operations could be largely reduced during the redundant reader identification phase. Moreover, LEO is a distributed scheme which does not need to collect global information for centralizing control, leading no communications and synchronizations among RFID readers. To evaluate the performance of the proposed techniques, we have implemented the LEO technique along with another redundant reader identification algorithm and other hybrid schemes. In experimental results, the LEO is shown to be effective and provides superior performance in terms of larger number of redundant reader could be detected and with lower algorithm overheads.","PeriodicalId":370753,"journal":{"name":"The 2nd IEEE Asia-Pacific Service Computing Conference (APSCC 2007)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128755616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is, however, a paucity of critical research assessing the strategic impact of SOA on the competitiveness of organizations. Some research literature in strategic management indicates that firms may gain a competitive advantage in rapidly changing market environments by concentrating on their dynamic capabilities - i.e., product flexibility and agility in organizational transformation in response to rapidly changing market conditions and customer requirements. The intent of this paper is to analyze the conduits through which service-oriented architectures (SOAs) may exert influence on dynamic capabilities within firms. The results could potentially assist in evaluating if and how the adoption of service-oriented architecture may help achieve key dynamic capabilities, giving the enterprise a competitive edge.","PeriodicalId":370753,"journal":{"name":"The 2nd IEEE Asia-Pacific Service Computing Conference (APSCC 2007)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129839920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methodology employs game-theoretic approach to determine whether it is advantageous to share information in situations of 1) competition-cooperation and 2) co-opetition. The decision allows partial sharing of information which we quantify on a scale from 0 to 100%. The focus of this research is developing a methodology to determine the optimal strategy to assist decision makers so we limit the choices to three specific shapes for the payoff functions: linear, concave nonlinear, and convex nonlinear. These three types of function; however, capture human behavior. Linear, concave, and convex utility functions are employed for players who prefer risk-neutral, risk averse, and risk loving, respectively. Finally, examples are provided to illustrate how the methodology can be used in practice.","PeriodicalId":370753,"journal":{"name":"The 2nd IEEE Asia-Pacific Service Computing Conference (APSCC 2007)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132214793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current clusters are designed to meet peak load with all the computing resources keeping running. However, this static reservation with full computing resources can not adapt to the time-varying computing requirement, and may incur low resource utilization and needless power consumption when the cluster system is underloaded. In this paper, we present an extensible architecture of cluster management system. This architecture promises a good extensibility by integrating job scheduler and resource manager in loose couple. Concentrating on the power saving of large-scale clusters, we describe the power model of servers, and based on the presented management system architecture, we propose a novel resource management way, adaptive pool based resource management (APRM) method, for adaptive provision of computing resources in accordance with the time- varying workload demand. APRM enables a cost- effective operating by providing dynamic computing capacity with automatic resource control. We validated APRM on the energy efficiency and quality of service (QoS) by simulation measurement, and the results showed that APRM yields significant power saving with little impact on QoS.","PeriodicalId":370753,"journal":{"name":"The 2nd IEEE Asia-Pacific Service Computing Conference (APSCC 2007)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132655180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
