We present a study concerning the applicability of a distributed computing technique to a million-page free-text document retrieval problem. We propose a high-performance DSIR retrieval algorithm on a Beowulf PC Pentium cluster using PVM message-passing library. DSIR is a vector space based retrieval model in which semantic similarity between documents and queries is characterized by semantic vectors derived from the document collection. Retrieval of relevant answers is then interpreted in terms of computing the geometric proximity between a large number of document vectors and query vectors in a semantic vector space. We test this DSIR parallel algorithm and present the experimental results using a large-scale TREC-7 collection and investigate both computing performance and problem size scalability issue.
