摘要： A task scheduling method and system, and a hardware task scheduler are disclosed, and pertain to the field of computer technologies. The hardware task scheduler provides task scheduling for a central processing unit CPU core to select a candidate task. After selecting the candidate task, the CPU core actively sends metadata of the candidate task to a first storage area, and actively sends a context of the candidate task to a cache, where the first storage area is located in storage space whose access speed is higher than that of a memory. When performing task switching, the CPU core reads the metadata of the candidate task from the first storage area, and reads the context of the candidate task from the cache. In this way, latency of obtaining the metadata and the context of the candidate task by the CPU core is reduced, and low-latency task switching is implemented.

摘要： This application discloses a cell camping method and an apparatus, to balance network load between different cells, and ensure service continuity of a terminal device. The method includes: After a terminal device camps on a first cell, a network device may send a first message to the terminal device, where the first message includes information about a second cell, the first cell corresponds to a first CC, and the second cell corresponds to a second CC; after receiving the second message, the terminal device sends a second message to the network device, where the second message may indicate the first cell and/or the second cell, or the second message may include measurement information of the first cell and/or the second cell; and the network device may determine, based on the second message, that the terminal device camps on the first cell or the second cell. This ensures network load balancing between different cells. In addition, the entire process does not require the terminal device to return from an RRC connected mode to an RRC idle mode, so that service continuity of the terminal device can be ensured.

摘要： This application discloses a clock synchronization method and a related apparatus in a distributed system. The distributed system includes a plurality of nodes, and the plurality of nodes include a master node and a plurality of slave nodes. The master node obtains a plurality of local clock offsets, where each of the plurality of local clock offsets indicates a clock offset between two nodes in the distributed system. The master node determines a global clock offset of a target slave node relative to the master node based on the plurality of local clock offsets, and sends the global clock offset to the target slave node. The target slave node obtains a clock reference value of a local clock, and then performs clock synchronization based on the clock reference value and the global clock offset. According to the solution provided in embodiments of this application, global error equalization can be implemented by determining the global clock offset by the master node. This helps improve clock synchronization precision of each node. Clock synchronization precision in this application can reach 1 microsecond.
