A QoS Guided Scheduling Algorithm - For Grid Computing (Correct)
....network. For non dedicated networks, since they have their own local jobs, they cannot provide exclusive service to remote jobs. So how to predict the job computation time for non dedicated network needs to be addressed. Research has been done on QoS and its related resource management, such as in [FoRS00, DiSe97]. The most current QoS concerns, however, are at the resource management level rather than at the task host scheduling level. In this study, we embed the QoS information into the scheduling algorithm to improve the efficiency and the utilization of a grid system. There are several ways to predict ....

....at every moment using application level feedback and monitoring. They aim at maintaining a sustainable resource usage. This is accomplished by means of changing the nature of the tasks that are carried out by the application. Adaptation presents the following advantages [Gecsei 97] Diot 95] Diot 97a] A lot of networks are best effort and their only way to guarantee a QoS would be through adaptation. Distributed Multimedia Systems, as a result of the evolution in network technology are becoming more heterogeneous, because high speed terminals will coexist with low end and mobile ones. ....

....sub systems for each application, and its inability to deal with dynamic changes in operating environments. To cope with the heterogeneity, the applications in the future will attempt to adapt their behavior to maximize the resources available to them in the different operating environments [9]. In addition, firstly, the users will change their preferences during a session for a number of reasons, such as the use of the application, location and cost. Secondly, the operating environment may also change during a session. For example, the computer may be moved from a wired network segment ....
....is warranted, this is achieved by repeating steps 2 to 4. Figure 1 summarizes the PNUT framework. In this paper, we will only focus on the synthesis of the protocol and its dynamic configuration. Details about the QoS manager and the determination of user preferences are described in [12, 9]. The function selection process and triggering of the reconfiguration can be found in [8] 2.1 Protocol Engine The implementation architecture of PNUT is shown in Figure 2. The application can either communicate directly with the application specific functions within the protocol engine, or ....

Does not scale to group communication environments Shortcomings of this type of QoS management architectures are discussed in [Diot97]. In this paper we will extend this work by examining the implication of adaptive application designs. 2.2 Adaptive Applications The tasks that an application carries out will be specific to it, and will be associated with data that is being handled. Thus an application will be characterized ....

A prototype of such a QoS manager is being currently being carried out [Landfeld97] and details of the scheme are given in [Diot97]. In the rest of this paper we will describe the extension of this work to systematically incorporate adaptive applications. 4.0 A Systematic View of Adaptation Adaptive applications attempt to adjust their operation in response to changes in the operating environment to maximize the user ....
