In this paper, we study the influence of performance prediction inaccuracy on task scheduling in grid environment from the context of task selection and processor selection, which are two critical phases in task scheduling. Formulas are established for the degree of misprediction, the probability that the predicted values for the performance of tasks and processors reveal different ordering characteristics from their real values. The impacts of different parameters on the degree of misprediction are also investigated extensively. Evaluation results show that an underestimate of performance can result in greater influence on task scheduling compared with an overestimate, while higher heterogeneity results in smaller influence.
