METHOD, DEVICE AND SYSTEM FOR INTER-PROCESS COMMUNICATION OF MANY-CORE PROCESSOR

摘要

Embodiments of the present invention provide a method, an apparatus, and a system for mutual communication between processes of a many-core processor, and relate to the field of many-core operating systems, so as to increase the speed of reading a message body and enhance user experience. The method is executed by a target kernel Kernal, 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 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 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.
