Abstract:

Grid technologies are emerging as the next generation of distributed computing, allowing the

aggregation of heterogeneous resources that are geographically distributed. The heterogeneous

nature of the grid makes it more vulnerable to faults which lead to either the failure of the job or

delay in completing the execution of the job. Checkpointing is one of the many fault tolerance

techniques which are used to make Grid more efficient and reliable. In this paper we have

developed an application checkpointing based fault tolerance technique for Alchemi based Grid

environment. In this technique application threads generate their checkpoints and store them in the

checkpoint table at the manager node.
