The Research of Host Load Predictions in Grid

According to the statistical characteristics of host load in the grid environment, we adopt fractal interpolation method to predict the future host load by the self-similarity and long-range dependence of host load. We simulate the prediction algorithm about the host load and evaluate the prediction performance by calculating the prediction evaluation indexes. And we analyze and compare prediction precision of our algorithm with AR(16) and "Patterns method". And finally find that fractal interpolation method is better than the other two algorithms on the performance of the grid environment.
