Modeling multicomputer systems with PARET

The authors discuss the parallel architecture and evaluation tool (PARET), a software package that provides a multicomputer system laboratory for studying the interaction of algorithms and architectures; the effects of varying physical resources on system performance; and alternate mapping, scheduling, and routing strategies, both static and dynamic. To handle the complexity of the problem and explore performance questions, PARET provides an interactive and animated environment in which the user exercises multicomputer models. The authors examined previous and related work, examine PARET´s unified modeling approach and its user interface. They present two PARET models to illustrate the modeling process.<>
