摘要：Grid is a collection of heterogeneous systems that are geographically distributed over a network. Grid systems can be used for solving large-sale computational problems such as video encoding, protein folding, etc. Video encoding is conversion of video from one format into another. The encoding process requires large computational power and takes a lot of time on conventional systems. Video file can be easily partitioned into smaller parts and these parts can be rejoined together to form full video file. This factor makes video encoding feasible on Grid. In this paper, video encoding from AVI to FLV video format is attempted on Grid environment and the performance of Grid is evaluated on basis of job execution time. Grid environment is implemented on virtual desktops connected through LAN. It is observed that AVI to FLV conversion on grid takes less time as compared to on a single system. The performance of grid system is 40% better than the conventional system. Further it is observed that the performance depends on problem at hand and other factors such as local processing load and network bandwidth.
