Abstract: Various embodiments provide a task processing method and apparatus. In those embodiments, when a first device determines that an available computing resource is less than a computing resource required by a to-be-executed AI task group, at least one second device from a valid device in a first area is selected. The first area is an area that uses the first device as a center and a valid communication distance of the first device as a radius, and the valid device in the first area is a collaborative computing device that is in the first area and that is connected to the first device. Still in those embodiments, a task in the to-be-executed AI task group is sent by the first device to each of the at least one second device; and an execution result of the sent task from the second device is received by the first device.

Abstract: A method for implementing collective communication, a computer device, and a communication system are provided, to resolve problems of high communication latency and resource consumption in the conventional technology. The method includes: identifying a work request having no communication dependency, and when forwarding work requests, directly forwarding the work request identified as having no communication dependency, and forwarding, after queue management, a work request that is not identified as having no communication dependency. According to the application, communication latency caused when the work request having no communication dependency is managed by using a queue can be avoided, and resource consumption caused by performing related management can be reduced, to improve overall communication performance of collective communication.
