In Vacuo and In Situ Evaluation of SIMD Codecs

Content Provider ACM Digital Library
Author Trotman, Andrew Lin, Jimmy
Abstract The size of a search engine index and the time to search are inextricably related through the compression codec. This investigation examines this tradeoff using several relatively unexplored SIMD-based codecs including QMX, TurboPackV, and TurboPFor. It uses (the non-SIMD) OPTPFor as a baseline. Four new variants of QMX are introduced and also compared. Those variants include optimizations for space and for time. Experiments were conducted on the TREC .gov2 collection using topics 701-850, in crawl order and in URL order. The results suggest that there is very little difference between these codecs, but that the reference implementation of QMX performs well.

About National Digital Library of India (NDLI)
NDLI logo

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.
