3-Dimensional Diffusion Equation

We see similar and better behavior on a larger three dimensional Diffusion Equation benchmark (Figure 9 and 10). After applying HPJOPT2 for the naive translation, the speedup of HPJava is 192% on a single processor and 567% on 8 processors. In general we expect 3 dimensional problems will be more amenable to parallelism, because of the large problem size.
