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.
