Abstract
We describe a simple abstract machine for parallel lazy evaluation.
The starting point is Sestoft's abstract machine for sequential lazy
evaluation and the development is influenced by an existing
operational semantics for parallel lazy evaluation. The general
structure of the machine is flexible enough to describe a variety of
parallel constructs. We illustrate this claim by considering fully
speculative evaluation, `par` and `seq`
combinators and limited processing resources.
