Parallel GRACE hash join on shared-everything multiprocessor: implementation and performance evaluation on symmetry S81
Masaru Kitsuregawa, S. Tsudaka, M. Nakano · 2003
The authors implemented a parallel hash join algorithm on a Symmetry S81 shared-everything multiprocessor environment and evaluated the performance. They evaluated the input/output (I/O) performance on a multiple-disk environment, and showed linear performance increase of up to eight disks. The performance of the implemented join operation was examined on each phase, and the effect of parallel processing by the multiprocessor and the multiple disks was clarified. It was concluded from the experimental result that on such a shared-everything multiprocessor system parallelism could be easily exploited for the construction of high-performance relational database systems.>
