Modeling and Analysis of a Parallel Nested Loop Join on Cluster Architectures
- 539 Downloads
We develop a concise but comprehensive analytical model for the well-known Nested Loop Join algorithm on cost effective cluster architectures. We concentrate on a limited number of characteristic parameters to keep the analytical model clear and focused. We believe that a meaningful model can be built upon only three characteristic parameter sets, describing main memory size, the I/O bandwidth and the disk bandwidth. We justify our approach by a practical implementation and a comparison of the theoretical and real performance values.
