| Abstract | Stream programs have to be crafted carefully to maximize the performance gain that can be obtained from stream processing environments. Manual fine tuning of a stream program is a very difficult process which requires considerable amount of programmer time and expertise. In this paper we present Hirundo, which is a mechanism for automatically generating optimized stream programs that are tailored for the environment they run. Hirundo analyzes, identifies the structure of a stream program, and transforms it to many different sample programs with same semantics using the notions of Tri-Operator Transformation, Transformer Blocks, and Operator Blocks Fusion. Then it uses empirical optimization information to identify a small subset of generated sample programs that could deliver high performance. It runs the selected sample programs in the run-time environment for a short period of time to obtain their performance information. Hirundo utilizes these information to output a ranked list of optimized stream programs that are tailored for a particular run-time environment. Hirundo has been developed using Python as a prototype application for optimizing SPADE programs, which run on System S stream processing run-time. Using three example real world stream processing applications we demonstrate effectiveness of our approach, and discuss how well it generalizes for automatic stream program performance optimization. |

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.
