Abstract
We have implemented a shared variable system for UNIX 4.2BSD that emulates a shared or common memory. This system is all user level code and requires no kernel modifications. It is accessible from a variety of languages. This shared memory system provides its service transparently to remote hosts across a local-area network. This system is being used in a real application--an automated factory. Shared variables are an appropriate communication paradigm in a real-time environment (in comparison to message passing or pipes).
