The Impact of the KSR1 Allcache Architecture on the Behavior of the DBS3 Parallel DBMS

New parallel architectures which aim at combining advantages of both Shared Memory (SM) and Distributed Memory (DM) architectures are emerging. The KSR1 machine is one of them. Although the parallel DBMS DBS3 runs on a shared memory machine, it uses a distributed computational model during query compilation. This feature makes it particularly well suited for studying the KSR1 approach for database applications. The objective of this paper is therefore to study the impact of the KSR1 architecture on the performance of DBS3, using some of the queries of the Wisconsin benchmark.
