With the increasingly widespread application of the network, a distributed operating system based on Linux cluster has been developing rapidly. This paper presents a kernel level distributed interprocess communication system model with support for distributed process synchronization and communication. This system model uses the System V interprocess communication programming interface and enhances it to provide functionality in distributed environments. A key feature of this system model is the use of the semaphore interface to support distributed synchronization and the implementation is done at the Linux kernel level to reduce the overhead. Finally, we realized this model introduced in this paper in redhat Linux cluster and test result show it is a good solution of distributed processes communication. Compared with other similar systems, the advantage of this system is that the implementation is done at the Linux kernel level to reduce the overhead and System V IPC API is easy to extend. User is easy to call the application interface of the distributed operating system, without considering any details of the network.
