Abstract
A lot of methodologies for a grid dependency study have been proposed like the analytical method has been developed by Roach. However, a method for practical problems has not been established. Generally, comparison from researchers' viewpoint among the computational result and other solutions (exact solutions, experimental results, etc) is the most popular way to check the grid dependency. In this case, it is important to efficiently collect many results about the same problem, and to compare such various results systematically. In this paper, we propose a concept of the comparison space, and a strategy of grid dependency study using comparison on the Grid.
