Dispelling Seven Myths about Grid Resource Management

摘要

Grid resource management is often viewed as scheduling for large long running computer intensive parallel applications. This view is narrow, as we will argue in this article. Grids today encompass diverse resources including machines users and applications. Moreover, grid users make different demands from different resources. Therefore grid infrastructures must adopt a greater responsibility than before for managing resources. Grid resource management cannot mean just scheduling jobs on the fastest machines but must also include scheduling special jobs on matched machines preserving site autonomy, determining usage policies, respecting permissions for use, and so on. In this article we will present seven 'myths' or common beliefs about grid resource management and dispel each myth by presenting counter-examples or 'observations.' These observations have been culled from our experience as well as work done by several experts in major grid-related projects.
