Deep Graph Library

Architecture

Show below, there are three sets of APIs for different models.

• update_all, proppagate are more global
• update_by_edge, update_to and update_from give finer control when updates are applied to a path, or a group of nodes
• sendto and recvfrom are the bottom primitives that update a message and node.

For Model developers

• Always choose the API at the highest possible level.
• Refer to the default modules to see how to register message and node update functions as well as readout functions; note how you can control sharing of parameters by adding a counter.
