Abstract
Most models that have been proposed (or implemented) so far for
exploiting both or-parallelism and independent and-parallelism have only
considered pure logic programs (pure Prolog).
We present an abstract model, called the Composition-Tree,
for representing and-or parallelism in full Prolog.
The Binding Array scheme is extended for And-Or parallel
execution based on the Composition-tree.
We also show how extra-logical predicates, such as cuts
and side-effects, can be supported in this model.
