We consider here the case of a code-coupling application consisting of two different programs, located on two different clusters linked by a high speed network, which regularly exchange data through a data redistribution. We study how to achieve this redistribution in an efficient way while minimizing transfer time and network congestion. We use to reach this goal a modeling of the problem using bipartite graphs. The chosen model allows us to take into account communications setup delays, the different available bandwidths and impose a limit of one simultaneous communication on each network interface (1-port model) and k simultaneous communications on the backbone. We execute an experimental validation of this model and use it to develop tw...
