In recent years, grid computing has emerged as a promising alternative to increase the capacity of processing and storage, through integration and sharing of multi-institutional resources. Fault tolerance is an essential characteristic for grid environments. As the grid acts as a massively parallel system, the loss of computation time must be avoided. In fact, the likelihood of errors occurring may be exacerbated by the fact that many grid applications will perform long tasks that may require several days of computation. In this paper, we describe the fault tolerance mechanism of the MAG grid middleware. We describe the fault tolerance components and how they interact with each other. The components were developed as mobile agents, forming a multi-agent society providing fault tolerance for node and application crashes.
