Main memory database algorithms for multiprocessors

Technical Report ·
OSTI ID:7249634
Database operations on multiprocessors with very large main memories are investigated. Only closely coupled systems with powerful processors and shared memory are considered. Removed from this environment is the crushing burden of disk access times, prompting the development of new algorithms and methods to make efficient use of the available resources. Improved methods of performing the relational join, an expensive operation, are the first topic of investigation in this dissertation. A number of multiprocessor main memory join algorithms are developed and their costs analyzed. The cost analysis and a graphical comparison of the algorithms provides insight into both the effectiveness of these machines and the methods used to develop algorithms in this environment. 84 refs., 54 figs.
