Zusammenfassung: | Three pointer based parallel join algorithms are presented and analyzed for environments in which secondary storage is made transparent to the programmer through memory mapping. P.A. Buhr et al. (1992) show that data structures such as B Trees, R Trees and graph data structures can be implemented as efficiently and effectively in this environment as in a traditional environment using explicit I/O. We show how higher order algorithms, in particular parallel join algorithms, behave in a memory mapped environment. A quantitative analytical model has been developed to conduct performance analysis of the parallel join algorithms. The model has been validated by experiments. |
