flow_graph (de)serialization ?

[nyue]

I am looking for the recommended way to serialize out the graph to some persistent form so that I can load them back for future execution. What are the recommended formats/best-practices ?

Kind regards

Hi,

Thank you for posting in Intel Communities.

You can use function_node to perform the computation on input data and can pass the result to successors. 

And you can use sequencer_node to forward messages in a sequence order after the execution is performed.

Please refer to the below links for more details.

The answer did not address the serialisation aspect but maybe I have not worded the question correctly.

I have gave it some thought and will probably perform the graph description (de)serialization via GraphML and using oneTBB flow_graph for the actual object (C++) that I will create to represent the dependency graph I am thinking of.

You can close the ticket if you want.

My plan is to use Boost::graph for the high level graph description and through it, serialize via GraphML

With in the boost graph node I will house the tbb flow graph node

I have posted a related question regarding Composition vs Inheritance for tbb graph node if you can respond to that, it would be great.

You can close the ticket.

Hi,

We cannot find your post regarding Composition vs Inheritance. Could you please share the post community link with us so that we can investigate the issue?

Here is the IsA vs HasA 

It has now been answered too.
