Abstract

This paper presents an analytical method to allocate processors in high performance parallel execution of recursive queries. The proposed method consists in computing (i) the number of tuples deduced by the transitive closure in account eventually of the selection clauses propagation and (ii) the number of economical processors. The main contribution of this paper is the presentation of an efficient method to compute the economical number of processors and the performance analysis which reveals the influence of DT on the allocation of processors number, response time and the generation of an execution plan.
