    Abstract: A control device is configured to control a computing device to perform big data distributed processing. The computing device is equipped with storage media in a plurality of deployment modes. The storage media include at least two of a local storage medium in the computing device, a global storage medium formed based on the local storage medium, an extended global storage medium, and an extended local storage medium. The control device obtains a service request for a big data service, determines storage media in at least one deployment mode from the storage media in the plurality of deployment modes, sends a control indication to the computing device, to indicate the computing device to execute a map (map) task in big data distributed processing on service data included in the service request, and stores obtained intermediate data in the storage media in the at least one deployment mode.

    Abstract: A first storage node communicates with at least one second storage node. A physical disk included in the at least one second storage node is mapped as a virtual disk of the first storage node. The method may include: receiving a first write request, where the first write request carries first to-be-written data; striping the first to-be-written data to obtain striped data, and writing the striped data to a physical disk and/or the virtual disk of the first storage node; and recording a write location of the striped data. For example, the technical solution may be applied to a storage system that includes an NVMe SSD.

    Abstract: An intelligent driving method comprising: obtaining feature parameters of a vehicle at a current moment and a road attribute of a driving scenario of the vehicle in a preset future time period; comparing the feature parameters at the current moment with feature parameters of a standard scenario in a scenario feature library; comparing the road attribute of the driving scenario of the vehicle in the preset future time period with a road attribute of the standard scenario in the scenario feature library; determining a total similarity of each scenario class to a driving scenario of the vehicle at the current moment based on comparing results; determining, as the driving scenario at the current moment, a first scenario class with a highest total similarity in N scenario classes; and controlling, based on the determining result, the vehicle to perform intelligent driving.

    Abstract: A data prefetching method includes a computing node obtaining information about accessing a storage node by a first application in a preset time period. The computing node determines information about prefetch data based on the access information. The computing node determines, based on the information about the prefetch data, a cache node prefetching the prefetch data, and generates a prefetch request for prefetching the prefetch data. The computing node sends the prefetch request to the cache node. The cache node performs a prefetching operation on the prefetch data in response to the prefetch request.

    Abstract: Embodiments of the present invention provide a data processing system and a data processing method. An MMIO address of a data request is obtained, where data stored in a PCIe storage device can be directly obtained from the MMIO address, and according to the MMIO address, a network adapter can directly read the data from the PCIe storage device of the data processing system, and transmit the data to a second data processing system, or directly write the data received from the second data processing system into the PCIe storage device. Therefore, the processing system can implement transmitting data directly from the PCIe storage device to the network adapter without using memory. During data transmission between the two data processing systems, a usage ratio of a resource, such as memory and a CPU, is reduced, and efficiency of data transmission is improved.
