Hello Randall,
I understood your code and tried on both single processor and dual processor. In single processor, the difference in processing time is pretty much similar. But in dual processor, I can see some its significant faster but no way near to your QUAD machine. Anyway this was very helpful learning experience.
One question: What the "Reentrant" option in execution properties does exactly? I was trying to find some explanation about these.
Thanks once again for everything.
