Description

Assessment of the model sensitivity to the network latency, revealing the impact of internode messages on the model scalability. Different strategies will be evaluated, as reducing internode communication time and frequency, limiting the communication overhead in general, improving the balance between the number of messages and the packet size as well as studying the optimal distribution of the model subdomains according to the computing resources and network topology.
