PARALLEL INFERENCE METHOD

PURPOSE:To decrease the number of idle CPUs and to improve the average working rate by securing such a constitution where a CPU selects the information via an information processor to store these information into a memory and one or plural ones of other CPUs perform the matching processes. CONSTITUTION:A general CPU registers a token into an inter-node CPU start area of a shared memory and returns to a fixed part selecting process 2 for token if an intra-node remains. Then the general CPU is kept under a waiting state until the matching process is through with all tokens registered in the inter-node CPU start area although the intra-node processing is completely through. When a rule satisfying a condition part remains after the matching process is through, the general CPU selects one rule and carries out it.
