Paper Details

An OCCAM@ implementation of prolog and its preliminary performance

Authors: Zhang, Kang


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 multitransputer system.
