摘要： A stream multiprocessor, a GPU, and related methods are provided. The stream multiprocessor executes thread blocks. Each thread block includes warps. The stream multiprocessor includes stream processors and a local dispatcher. Each stream processor executes one or more warps. The local dispatcher includes a warp state table, a warp resource detection unit and a warp launching unit. The warp state table records dispatching states and processing states of warps of the thread blocks. The warp resource detection unit selects all the first warps of a first thread block and at least one second warp of a second thread block according to hardware resources available to the stream multiprocessor and hardware resources required for thread blocks. The warp launching unit dispatches the first warps to idle stream processors and at least one second warp to at least one idle stream processor.

摘要： A system includes a high-bandwidth inter-chip network (ICN) that allows communication between neural network processing units (NPUs) in the system. For example, the ICN allows an NPU to communicate with other NPUs on the same compute node (server) and also with NPUs on other compute nodes (servers). Communication can be at the direct memory access (DMA) command level and at the finer-grained load/store instruction level. The ICN system and the programming model allows NPUs in the system to communicate without using a traditional network (e.g., Ethernet) that uses a relatively narrow and slow Peripheral Component Interconnect Express (PCIe) bus.

摘要： 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.
