Abstract
An inter-manycore communications method includes applying, by a service manager process, to a microkernel operating system for shared memory, and mapping shared memory, which is allocated by the microkernel operating system, to virtual address space of the service manager process; receiving and recording a service identifier of a system service process and a second shared memory address that corresponds to the service identifier; searching, according to a service identifier carried by a system service request, for the second shared memory address that corresponds to the service identifier carried by the system service request; and sending the service identifier carried by the system service request, a first shared memory address, and the second shared memory address that corresponds to the service identifier to a user process. According to the method, a problem that communication between a user process and a system service process needs multiple context switches can be solved.
