Abstract
In distributed systems, the techniques of migration have been extensively studied by simulation, implementation, and successful results were accepted in most schedulers for grid computing. In effect, migration is capable of improving the load balancing, reliability, and QoS of distributed systems. However, migration can also be accompanied by negative effects. It may not only consume a considerable amount of resource, but also come with migration failure. In this paper, we present some migration decision strategies and experimental results on job migration. Through different policies, it makes decision to select and migrate to the next available node. Here we use some probability and statistic methods, like Markov chain and Poisson process, to improve the performance of the decision-making. The target node is selected such that it may provide a high availability environment and thus may finish the execution with high probability.
