SMART: A Simulator of Massive Architectures and Topologies

Many important results in the area of computer architecture have been achieved using simulat-ors. In this paper we present SMART, a simula-tor of parallel architectures. SMART provides a exible and eecient simulation environment that includes the most common interconnection networks and routing algorithms and gives the user basic mechanisms to deene the internal structure of the processing nodes. To show the characteristics of SMART, we analyze the relations between the degree of overlapping of the transpose FFT algorithm and the presence of a communication processor on a fat tree and on a bi-dimensional cube that have the same normalized communication bandwidth.
