Abstract: A data writing method includes determining first data to be written into a circular storage queue; obtaining a global write pointer of the circular storage queue, where the circular storage queue includes a plurality of storage areas, each storage area includes a plurality of subareas, and the global write pointer points to a first storage area of the plurality of storage areas; obtaining a first write pointer of the first storage area, and determining a size of allocated space in the first storage area based on the first write pointer of the first storage area; if the size of the allocated space in the first storage area is less than a size of space of the first storage area, performing an FAA operation on the first storage area, to allocate a first subarea in the first storage area; and writing the first data into the first subarea.

Abstract: Example inter-process communication methods and apparatus are descried. One example method includes writing, based on a calling convention, communication information into a register group of a first execution entity of a sending process. First data of target data is written into a stack memory of the first execution entity. The communication information includes a first value indicating a data amount of the first data, and the target data is data to be sent by the sending process to a first receiving process. Information in the register group of the first execution entity is replicated to a context of the first execution entity. The first data from the stack memory of the first execution entity is replicated to a stack memory of a second execution entity of the first receiving process based on the first value in the context of the first execution entity and the address of the stack memory.
