| Abstract | The performance analysis of a server application and the sizing of the hardware required to host it in a data center continue to be pressing issues today. With most server-grade computers now built with "frequency-scaled CPUs" and other such devices, it has become important to answer performance and sizing questions in the presence of such hardware. PowerPerfCenter is an application performance modeling tool that allows specification of devices whose operating speeds can change dynamically. It also estimates power usage by the machines in presence of such devices. Furthermore, it allows specification of a dynamic workload which is required to understand the impact of power management. We validated the performance metrics predicted by PowerPerfCenter against measured ones of an application deployed on a test-bed consisting of frequency-scaled CPUs, and found the match to be good. We also used PowerPerfCenter to show that power savings may not be significant if a device does not have different idle power consumption when configured with different operating speeds. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
