Abstract

This paper describes a garbage collector for an implementation of a lazy functional language using parallel graph reduction. The garbage collector is an extension to the Appel-Ellis-Li garbage collector. The extension consists of two parts:

Firstly, generations has been added: this often decreases the garbage collection time with nearly 20%. This shows that generational garbage collection is useful even for a lazy functional language implemented with graph reduction (which performs a lot of updates).

Secondly, the Appel-Ellis-Li garbage collector has been changed so that it cart collect garbage processes (which is essential if we do speculative evaluation).
