The four-stroke reduction engine [PDF]

Proceedings of the 1986 ACM conference on LISP and functional programming - LFP '86, 1986
© 1986 ACM. Functional languages are widely claimed to be amenable to concurrent execution by multiple processors. This paper presents an algorithm for the parallel graph reduction of a functional program. The algorithm supports transparent management of parallel tasks vlth no explicit communication between processors.
