Virtual batching approach for green computing

Due to tremendous growth of Industrial activities globally, the climate of the earth is gradually changing. There is a need to pay special attention towards the issues, need and methods that affect the environment hazards. This paper focuses on the techniques available to cope with the challenges of green computing. It studies the methodologies employed in various scenarios, and addresses the vulnerability of each of such methods accordingly. Many techniques for dealing with the above issues like DVFS, performance monitoring are available. DVFS ensures energy conservation and CPU utilization for moderate workloads whereas request batching is well suited for light workloads. The paper studies that request batching can be realized on a virtual environment to provide energy utilization in the web servers. It also focuses the other improved techniques by performing the batching at the thread level, so that maximum utilization can be obtained by parallelism-aware request batching.
