%X The paper presents an execution model for Prolog, which
attempts to exploit the parallelism mainly at the argument
level through the unification operation. The model,
consisting of a number of virtual machine instructions, has
been implemented in Occam2 on a Transputer Development
System (TDS). The performance of the pure software
implementation has been evaluated in real\-time. The speed,
as assessed by running a few hand compiled benchmark
programs on the TDS with a single transputer, ranges from
7\-18 KLIPS. The paper gives some details of the
performance, and then proposes a dataflow\-based
functionally distributed configuration of the
