Performance by Parallel Inference 

Fig.3 shows the speedup of two inference engines. We obtained more than 
50-fold speedup using the 64PEs of the Multi-PSI.

Outline of demonstration 

We demonstrate how the parallel legal reasoning system HELIC-II solves 
Mary's case. First, representation of Mary's case is explained. Second, the 
consequences drawn by HELIC-II are shown. Third, an inference tree of a 
consequences is explained. Fourth, more detail is explained using natural 
language style output.
