Abstract

Many parallel algorithms can be modelled as directed acyclic task graphs. Recently, Degree of Simultaneousness (DS) and Degree of Connection (DC) have been defined as the two measures of parallelism in algorithms represented by task graphs. However, those definitions are not appropriate measures of parallelism when task graphs are to be executed on a multiprocessor system with N processors. In this paper, we give new definitions of DS and DC using a new parameter we call Uniformity Factor (UF). These new definitions are more meaningful when an acyclic task graph is to be executed on a multiprocessor system with N processors.
