A Scavenger Grid for Intranet Indexing

摘要

Digital library services, such as searching and browsing, are increasingly needed in more restricted environments than the public Web. This paper proposes a scavenger Grid of idle desktop workstations to support computationally-intensive indexing services. A prototype software system was developed using commodity Grid middleware and information retrieval tools. This system demonstrated that the overhead incurred by Grid middleware is manageable and that performance gains are significant.
