=== 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.
