| Abstract | Cloud computing benefits extensively from economies of scale to provide cost effective computing. Recently, reliability has been introduced as a potential tradeoff point for delivering compute resources while decreasing further the price of cloud resources. The usage of fair market conditions create an environment where sellers and buyers of compute resources can benefit from trading their resources. The resource use efficiency can potentially be achieved as a result. While there are many advantages to the usage of auction-based infrastructure there are currently no practical computing platforms that can harness such volatile environments effectively. This research work reports a methodology and a toolkit designed to address the challenges of using volatile cloud-based auctioned resources for MPI applications. Specifically we emphasize the use of dynamically adjusted optimal checkpoint-restart (CPR) intervals. We discuss an initial analytical model for dealing with price histories and selecting optimal checkpoint intervals. Also we describe the SpotMPI toolkit that can be used to achieve practical execution of MPI application on volatile auction-based cloud platforms. The result of this exploration is the synthesis of intrinsic dependencies that exist in MPI-based parallel applications with the publicly available price histories of HPC cloud resources on the Amazon cloud. We study algorithms with different computing v.s. communication complexities. Our results show counter-intuitive insights into the optimal bidding and application scaling strategies. |

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.
