<div>From the documentation I found the flow for the creation of an application code is the following:</div>
<div>1. Create a Network and register components</div>
<div>2. Set network size and layout</div>
<div>3. Set components and number of variables for nodes/edges</div>
<div>4. Set up the network <br>
</div>
<div>5. Distribute the network </div>
<div><br>
</div>
<div>Following that flow, from point 1 to point 4 the Network is "owned" only by the 0 rank processor while after point 5 the network is partitioned and "owned" by the n processors involved in the computation (according to the partitioner used).

<div>Correct. Currently, DMNetwork only supports sequential setup of network. I just started parallelizing it. I'll let you know when I'm done.</div>

<div>I was trying to let all the n processors involved read a portion of the network in such a way that the flow listed before will be a multiprocessor process and not restricted only to the rank 0 processor (parallel input data). In this way after point 4
I will have a distributed network and I don't need to call DMNetworkDistribute(). Unfortunately the documentation I found doesn't explain how to do that, so I would like to ask you if it is feasible and if you have some examples or documentation that you can
share for this purpose. <br>

<div>It is not supported yet. Internal works are needed. You may follow my development branch</div>
