title: Use of vector processing to search the Cambridge Structural Database.
abstract: The Cambridge Structural Database (CSD) is a vast numerical resource of crystallographic data. The January 1989 release contains over 70,000 entries, and the data acquisition rate currently increases about 15% per annum. To be able to provide adequate response times for interactive data retrieval, using the new (1988) CSD file format, a vectorized search procedure has been developed as a modification of the CSD program QUEST. This procedure employs the pipelined vector facilities of the CONVEX C120 system to perform bitscreen logic, resulting in response times for arbitrary queries in the order of seconds, almost independent of the size of the database.
