- | < | + | In this page the adaptive mechanism implemented by GAIA is shown using some videos. Each video represents a simulation run in which a given number of wireless stations is modelled. |

+ | The first video shows the distributed simulation of 9999 mobile wireless hosts using 3 execution units (e.g. CPUs), each unit manages the evolution of 3333 hosts. The initial allocation of the simulated hosts on the execution units is random. | ||

+ | ====== Adaptive distributed simulation, initial allocation in stripes ====== | ||
+ | |||
+ | In this case the initial allocation of mobile wireless hosts is arranged in stripes. This means that, at least initially, the amount of local communication is quite high. In this case, the role of the adaptive mechanism is to maintain a good clustering of the simulated hosts. | ||

+ | |||
+ | In this case the adaptive mechanism is turned OFF, in a few timesteps the clustering becomes very poor and there is a performance degradation. | ||
