Abstract: A method, an apparatus, and a system for mutual communication between processes of a many-core processor are provided that relate to the field of many-core operating systems The method is executed by a target kernel, where the target kernel corresponds to a target processor core. The method includes acquiring a message header of a message from a quick message channel (QMC); executing a central processing unit (CPU) pre-fetching command according to the message header, so that a message body that is in the message stored in a shared memory and corresponds to the message header is loaded to a cache that corresponds to the target processor core; and switching to a target process, so that the target process acquires the message body from the cache. The embodiments of the present invention apply to a scenario of mutual communication between processes of a many-core processor.
