This paper describes a resource broker whose main function is to match available resources to user needs. The resource broker
provides a uniform interface for accessing available and appropriate resources via user credentials. We also focus on providing
approximate measurement models for network-related information using NWS for future scheduling and benchmarking. We first
propose a network measurement model for gathering network-related information (including bandwidth, latency, forecasting,
error rates, etc.) without generating excessive system overhead. Second, we constructed a grid platform using Globus Toolkit
that integrates the resources of five schools in Taichung integrated grid environment resources (TIGER). The resource broker
runs on top of TIGER. Therefore, it provides security and current information about available resources and serves as a link
to the diverse systems available in the Grid.

Grid computing employs heterogeneous resources which may be installed on different platforms, hardware/software, computer architectures, and perhaps using different computer languages to solve large‐scale computational problems. As many more Grids are being developed worldwide, the number of multi‐institutional collaborations is growing rapidly. However, to realize Grid computing's full potential, it is expected that Grid participants must be able to share one another's resources. This paper presents a resource broker that employs the multi‐site resource allocation (MSRA) strategy and the dynamic domain‐based network information model that we propose to allocate Grid resources to submitted jobs, where the Grid resources may be dispersed at different sites, and owned and governed by different organizations or institutes. The jobs and resources may also belong to different clusters/sites. Resource statuses collected by the Ganglia, and network bandwidths gathered by the Network Weather Service, are both considered in the proposed scheduling approach. A dynamic domain‐based model for network information measurement is also proposed to choose the most appropriate resources that meet the jobs' execution requirements. Experimental results show that MSRA outperformed the other tested strategies. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献
