Performance evaluation of fault tolerance techniques in grid computing system

As fault tolerance is the ability of a system to perform its function correctly even in the presence of faults Therefore different fault tolerance techniques (FITs) are critical for improving the efficient utilization of expensive resources in high performance grid computing systems and an important component of grid workflow management system This paper presents a performance evaluation of most commonly used FTTs in grid computing system In this study we considered different system centric parameters such as throughput turnaround time waiting time and network delay for the evaluation of these FTTs For comprehensive evaluation we setup various conditions in which we vary the average percentage of faults in a system along with different workloads in order to find out the behavior of Firs under these conditions The empirical evaluation shows that the workflow level alternative task techniques have performance priority on task level checkpointing techniques This comparative study will help to grid computing researchers in order to understand the behavior and performance of different FTTs in detail (C) 2010 Elsevier Ltd All rights reserved
