Grid-JQA: A New Method for Matching in Grid Environment

The Grid is an emerging technology for enabling resource sharing and coordinated problem solving in dynamic multi-institutional virtual organizations. This paper presents algorithms, methods, and software for a Grid resource manager, responsible for resource broke ring and schednling in Grids. The broker selects computing resources based on actual joh requirements and a number of criteria identifying the available resources, with the aim to minimize rbe turnaround rime for the individual application. In pervious work, we proposed Grid-1QA [H] [9]. In this work we propose an aggregation formula for the QoS parameters. The fonnula is a unit less combination of the parameters together with weighting factors. It is shown that the formula needs 10put into a threshold consideration. A discussion on the threshold and its level is also provided. The paper is finalized by the results obtained from simulation and a comparison study,
