Dgl.distributed.load_partition
WebJun 15, 2024 · Training on distributed systems is different as we need to split the data and maximize data locality for each machine. DGL-KE achieves this by using a min-cut graph partitioning algorithm to split the knowledge graph across the machines in a way that balances the load and minimizes the communication. WebAdd the edges to the graph and return a new graph. add_nodes (g, num [, data, ntype]) Add the given number of nodes to the graph and return a new graph. add_reverse_edges (g …

WebJul 1, 2024 · This includes two steps: 1) partition a graph into subgraphs, 2) assign nodes/edges with new IDs. For relatively small graphs, DGL provides a partitioning API :func:`dgl.distributed.partition_graph` that performs the two steps above. The API runs on one machine. Therefore, if a graph is large, users will need a large machine to partition … Webdgl.distributed.load_partition(part_config, part_id, load_feats=True) [source] Load data of a partition from the data path.

I was wondering if DGL was compatible with pytroch’s DDP (Distributed Data Parallel). if it was better to use DGL’s native distributed API?
