Abstract: A data processing method and apparatus, and a heterogeneous system, pertaining to the field of computer technologies are provided. The heterogeneous system includes a processor connected to an accelerator. A secondary memory is connected to the accelerator. The processor is configured to write to-be-processed data into the secondary memory and trigger the accelerator to access and process the to-be-processed data stored in the secondary memory according to a processing instruction. The accelerator is configured to write a processing result of the to-be-processed data into the secondary memory and to trigger the processor to read the processing result. Processing efficiency is enhanced by reducing the number of times of interaction between the processor and the accelerator and simplifying the procedure for data processing.

Abstract: A computing system includes a host device and an acceleration device. The host device is in a communication connection with the acceleration device. The host device is configured to send invocation information to the acceleration device. The invocation information indicates a storage address of the first data. The acceleration device is configured to receive the invocation information from the host device, obtain the first data from a memory based on the storage address, and perform the to-be-processed task based on the first data to obtain a processing result. The host device notifies the acceleration device of the storage address, and the acceleration device directly obtains the data from the memory based on the storage address such that the host device is prevented from obtaining the data from the memory.

Abstract: This application provides a data processing method. The method is applied to a server, the server includes a first container and an Android driver (240), and a first service manager is deployed in the first container. Each container is allocated its respective private memory (2412, 2422, and 2432) and private service linked list (2411, 2421, and 2431), so as to avoid a problem in a conventional technology of data inconsistency and affected service processing caused by sharing of same memory by a plurality of containers.
