Resource Reservation in Shared Environments Based on the Prediction of Time
It is an important method that resource reservation can guarantee QoS of the grid jobs. Introduces resource reservation into shared environments to lead to the problem that queuing jobs mean waiting time increase heavily, then proposes an policy of resource reservation based on the prediction of waiting time. Queuing jobs include remote jobs and local jobs. Introduces priority policy, and predicts the waiting time of different priorities to calculate the cost to choose resource.Experimetal results show that prediction relative error and scheduling algorithms based on the cost are practically effective and have a real potential.
