Green Computing which is a concept of using technology to become more practical, efficient and cost-efficient in energy use, becomes a concept which is being developed at this time. One method that can be analyzed and developed is the use of a single processor on each computer, but has a performance that could rival the use of multiple processors in order to get better performance. Besides eco-friendly principles also become an integral part of the development of this technology. So optimizing the performance of computers using a single processor of choice in order to optimize the use of technology in today.
