For several years now; most of the growth of computing power has been made possible by exploiting parallel CPUs on the same chip; unfortunately; state-of-the-art software tools for the simulation of declarative; objectoriented models still generate single-threaded simulation code; showing an increasingly disappointing performance. This paper presents a simple strategy for the efficient computation of the right-hand-side of the ordinary differential equations resulting from the causalization of objectoriented models; which is often the computational bottleneck of the executable simulation code. It is shown how this strategy can be particularly effective in the case of generalized physical networks; i.e.; system models built by the connection of components storing certain quantities and of components describing the flow of such quantities between them.
