The estimation of resource needs for data manipulation is fundamental to the operation of the Grid.Situations will arise when it will be necessary to determine which is more expedient, downloading a replica from a remote site or recreating the data from scratch.This paper explores the possibility of predicting the behavior of the ATLAS applications to improve resource usage in a Grid environment by studying the parameters that affect the execution time performance of event generation, detector simulation and event reconstruction.
