Abstract: | In this paper we describe the design and implementation of
ParSets, a means of exploiting parallelism in the SHORE
OODBMS. We used ParSets to parallelize the graph traversal portion of
the OO7 OODBMS benchmark, and present speedup and scaleup results from
parallel SHORE running these traversals on a cluster of commodity
workstations connected by a standard ethernet. For some OO7
traversals, SHORE achieved excellent speedup and scaleup; for
other OO7 traversals, only marginal speedup and scaleup occurred. The
characteristics of these traversals shed light on when the ParSet
approach to parallelism can and cannot be applied to speed
up an application.
