This session was devoted to discussion of primitives for synchronizing the execution of concurrent processes. Jack Dennis introduced the session by noting that concurrent activity in a computer systems leads to the possibility of nondeterminacy. While most users with applications programs do not want nondeterminate results~ some applications are inherently nondeterminate in part, e.g.~ an airline seat reservation system. At a lower level, the prograrmners of the operating system itself need to write both determinate and nondeterminate programs. The challenge is in providing primitives at each level in a system which guarantee determinacy when that is required~ yet allow the construction of nondeterminate programs when that is required. As a basis for discussionj Dennis invited Rick Holt to make a short presentation on the levels in a computer system and their relationship to synchronizing primitives.
