  • Patent number: 11729268
    Abstract: Various embodiments of the present disclosure relate to a computer-implemented method, a system, and a storage medium, where a graph stored in a computing system is logically divided into subgraphs, the subgraphs are stored on different interconnected (or coupled) devices in the computing system, and nodes of the subgraphs include hub nodes connected to adjacent subgraphs. Each device stores attributes and node structure information of the hub nodes of the subgraphs into other devices, and software or hardware prefetch engine on the device prefetches attributes and node structure information associated with a sampled node. A prefetcher on a device interfacing with the interconnected (or coupled) devices may further prefetch attributes and node structure information of nodes of the subgraphs on other devices. A traffic monitor is provided on an interface device to monitor traffic. When the traffic is small, the interface device prefetches node attributes and node structure information.
