Abstract: The commodity market model was compared with the auction model from the aspects of resource allocation and task scheduling based on eco nomic models in computational grids. To evaluate these two models, we simulated them respectively in underdemand and excessdemand circumstances. We have examined the overall price stability, market equilibrium, producer efficiency, and consumer efficiency by simulation and drawn a conclusion that the commodity market model is more suitable to computational grids, and makes the whole resource market more fair, stable and efficient.

Key words: computational grid, commodity market model, auction model
