Continuation-Based Control in the Implementation of Parallel Logic ProgramsJohn S. Conery, Department of Computer and Information Science, University of Oregon

Abstract: Continuations are used to define the flow of messages
between low level tasks in a parallel logic programming language. A
combination of compiler and runtime operations reduces message traffic
by up to 50% when success continuations are passed as parameters in
messages that start new processes. Continuations are also the key to
fast task switching, a critical operation in this fine grain parallel
system. Data from sample programs shows the effectiveness of
continuations in reducing message traffic and the speed with which
task switches are performed on a typical host architecture. Keywords: continuation, logic programming, implementation, parallel, message passing |
