Using Checkpoint For Implementing Fault- Tolerant On Desktop Grids

Grid computing uses massive power of idle cycles of PC's.Desktop grids is nothing using the idle cycles of desktop PC's for computing large scale applications. There are many fields which requires large scale massive power such as scientific fields to handle complex and demanding problems. Desktop grids uses widely distributed grids the probability of occurring fault is more. Desktop Grids are being increasingly used as the execution platform for a variety of applications that can be structured as Bag-of-Tasks (BoT)[1]. In this paper we proposes a fault tolerant fair scheduler for bag of tasks application on desktop grid, which ensures error free transmission of data and performing tasks by using resources and also fair sharing of resources. Fault tolerant is implemented on desktop grid by using check point
