Abstract [en]

We present a model for OR parallel execution of Horn clause programs on a combined local and shared memory multiprocessor system. In this model, the shared memory only contains control information that guides processors requesting a job to independently construct the environment required to get a new job. Each processor has a local memory containing its own binding environment. This reduces the traffic to the shared memory and allows each processor to process its job with high performance. Each processor is almost the same as Warren's Abstract Machine (WAM). A method for nonshared memory multiprocessor architectures is outlined. We also present some preliminary results of an experimental investigation of the model.
