Star modeling on IBM RS6000 networks using PVM

The authors present the parallelization of a Monte Carlo radiative transfer code on a workstation network using PVM. In order to measure parallel performances on heterogenous networks, they propose a generalization to heterogeneous parallel architectures of the classical speedup and efficiency definitions. They apply these formulae to the study of their parallel code. They then show some scientific results obtained using this program on a Gflops peak performance network
