Abstract
A data synchronization method and apparatus, and a device and a storage medium are disclosed. The method comprises: constructing first-level physical topologies between acceleration devices of the same type, and constructing second-level physical topologies between acceleration devices of different types, the acceleration devices in the second-level physical topology are connected by using a cache coherence protocol; performing first processing on to-be-synchronized data among the acceleration devices through scatter reduce communication based on the first-level physical topologies, and performing second processing on data after the first processing among the acceleration devices through scatter reduce communication based on the second-level physical topologies; and performing third processing on data after the second processing among the acceleration devices through all gather communication based on the second-level physical topologies, and performing fourth processing on data after the third processing among the acceleration devices through all gather communication based on the first-level physical topologies.
