I managed to get a Grid Simulation working.... here is a screenshot of it. I named it SimGrid, and it works in conjunction with Sim01 as a programming tool. First you work out your entry on Sim01 for a single cell, then paste the hex code into the appropriate cell in the Grid. The code to generate it can scale to arbitrary dimensions, limited by the screen and Windows resource handles.
In this simulation, every cell is loaded with the code required to pass each bit through the cell, and have it emerge on the opposite side. Its a fairly easy way to check for logic flaws in the simulator. Here we see a bit from the left side propagating all the way across to the right.
I feel that it's reasonable to estimate I can emulate an arbitrary grid of these, even as many as 1000x1000 without problem. The problem now is to find a problem domain that is appropriate for the architecture to use as a baseline for performance evaluations. I need to make sure it's going to be quick enough once cast into silicon to have any commercial value. I'm hoping it will be fast enough for the Exaflop realm, but I have to real way to tell at this point in time.
I'm starting to dig around for silicon simulation resources, as well as a place to do fabrication of this as an ASIC should I find funding.
I feel like Tesla probably felt when he got the idea of polyphase power straight in his head.... BitGrid has enormous potential, but now is the time for a lot of blood sweat and tears to make it come into being.
