Abstract

This article wants to show that, contrary to popular belief, solving some problems on a message passing architecture (MPA) may be faster than solution on an abstract EREW PRAM machine. The reason is that communication on MP architecture can be hidden by SW pipelining, but shared memory communication in PRAM cannot be, in principle, overlapped with processing. In this paper we present an example of artificial neural network implementation, where, under certain circumstances, MPA can provide faster execution and a better speedup than EREW PRAM.
