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.
