| Abstract: | Task scheduling plays a critical role for achieving high performance, which has been an active area of research for several decades. In this paper, models for task scheduling in grid computing are surveyed. First with the application model, the divisible load model is recommend; followed by the platforms model, including processor model and network model, which is the main difference between traditionally platforms and the grid computing; next is the objective model. Several objectives are discussed and none of a single objective is satisfying, the paper proposes an integrated model to compete the problem. Finally some conclusions are drawn. |
