Robust fault tolerant job scheduling approach in Grid environment

Grid computing is becoming a new face of distributed computing, allowing the aggregation of geographically dispersed resources. The Dynamic and heterogeneous nature of Grid makes it more vulnerable to various faults which enforces the failure of job, delay in completion of job or even execution of job from the starting point. In this paper, the empirical analysis for different faults is carried out and also discussed nine fault tolerant job scheduling approaches to deal with these faults, for each approach comparative quantitative analysis is carried out. Though there is need of providing better resource sharing, improved resource utilization and computational speed for computationally intensive applications. Although the technique based on the combination of RFOH and application checkpointing approach may provide robust fault tolerant job scheduling.
