What is GRAM

Resource Management System (RMS), which manages the Grid resources and matches the applications’ requests to the proper resources, is one of the most important and complex parts in Grid systems. In fact, because of the complexity of Gird environment, one resource management approach alone cannot satisfy different applications’ requirement. Therefore, a novel Adaptive Resource Management (ARM) mechanism is provided here. This mechanism is based on multidimensional Grid QoS, which dynamically organizes Grid resources into Task Resources for feasible distribution. Moreover, this management mechanism can select appropriate management approach according to different applications’ requirements, which is well adapted to dynamic Grid environment.
