Parallel architectures for database processing should provide parallel I/O as well as parallel CPU capability. Two issues that arise in such systems are data combination and nonuniform data distribution. The authors' interest has been in studying distributed memory architectures, specifically hypercubes, for parallel database processing. The cube interconnections support efficient data combination for the various database operations and nonuniform data distributions are handled by dynamically redistributing data utilizing these interconnections. Selection and scalar aggregation operations are easily supported. An algorithm for the join operation is discussed in some detail. A comparison of the cube and another multicomputer database machine, viz., SM3, is provided and the performance of the join operation in these systems is described.
