In parallel database systems, distribution of the data among the processors has a signiicant impact on the response time and throughput of the system. The beneets of parallelism (using multiple processors to execute a query) must be balanced against its costs (communication, startup, and termination overhead). We formalize the problem of minimizing overhead(More)
The computing time beneets of parallelism in database systems (achieved by using multiple processors to execute a query) must be weighed against communication, startup, and termination overhead costs that increase as a function of the number of processors used. We consider problems of minimizing overhead subject to allocating data among the processors(More)
