| Abstract: | To improve the utilization ratio of resources and users' satisfaction degree of grid services,grid resource scheduling algorithm based on double Quality of Service(QoS)named Senior was proposed.In the implementation process of scheduling algorithm,the mode of scheduling strategy was derived,according to the attributes of job and resource,and the specified parameter information.Double constraints of gridlets deadline and network bandwidth were defined as double attribute constraints based on the thought of c... |
