Report of session on concurrency

Michael D. Schroeder

Abstract

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.
