One factor that greatly influences the performance of parallel expert systems is the amount of dependence between the rules. I want you to create two sample production systems and test the results. The first production system should be very modular (little or no dependencies between rules on different processors). The second production system should contain many dependencies between the rules. Indicate whether or not the goal was reached. Record the timings as these databases are run both on the Sequent with 3 or 4 (your choice) processors, and on a single machine using 3 or 4 threads.
