Nettetscheduling domain—e.g., ensuring that the graph neural network can express properties such as a DAG’s critical path. Our neural net-work design substantially reduces model complexity compared to naive encodings of the scheduling problem, which is key to efficient learning, fast training, and low-latency scheduling decisions. Nettetlearning-based approach to scheduling DAG tasks. The algorithm employs a rein-forcement learning agent to iteratively add directed edges to the DAG, one at a time, to enforce ordering (i.e., priorities of execution and resource allocation) of “tricky" job nodes. By doing so, the original DAG scheduling problem is dramatically
