Learn How to Develop a Distributed Game of Life with DDS It will be shown that by leveraging advanced DDS data-management features, system developers can off-load most of the complexity associated with the distribution and fault-tolerance aspects onto the infrastructure and focus on the application logics. The presented Distributed Life system will be able to deal with real-life system requirements like fault tolerance, scalability and deployment flexibility. It will show how a distributed version of Life can be implemented using the Data Distribution Service (DDS) standard from the Object Management Group (OMG).
This webinar is intended as a combination of the two: education and fun. Many programmers have written implementations of Life at some point, probably in an educational context or maybe just for fun. Life, as it is called for short, has been able to capture the fascination of many programmers ever since it was published – mostly because of the surprising behavior it can result in. A set of four simple transition rules prescribe how the cells in the grid evolve from one generation to the other. It is a cellular automaton that runs on a rectangular grid of cells, each of which is either alive or dead.
:: Generate grid 'A'.The Game of Life is a famous zero-player game that has been devised by John Conway more than forty years ago. What I would like to do next is figure out a way to exit gracefully as the only way currently is to press CTRL+ C. I am pretty satisfied with the performance now, I don't think I can get much more speed out of it. So here is the 'final' code, it works much much faster than before. Thus I can inject them into my cell variable and expand this to get the value its assigned. So what this is doing is expanding and assigning !X! and !Y! to variables local to the FOR loop %%a and %%b. In the end I tried a FOR loop and this worked very nicely. !A! but this just resulted in XY because the script was trying to expand variables !A!. I tried all kinds of double-expansion-nested syntax, e.g. So after I had calculated the x and y value of the neighbouring cell that I wanted to check, I had to get the value of that variable somehow. I am storing each cell value in a variable named A e.g. However the main issue I ran into here was variable expansion. So I knew I had to move the logic from the function GETNCOUNT into the main processing loop. So calling a function once per cell was very expensive time-wise. Ok so it turns out that the using CALL in a batch script is very slow.

:: Also for safety, delete any Grid 'B' cells that might be in memory I think the slowest part is the function GETNCOUNT - this gets the count of the neighbouring 'live' cells so it is called once per cell. However - it is slow, very slow on a large grid. I like writing in batch - its restrictions and limits are its appeal. Just for fun I have written a Conway's Game of Life in cmd batch file.
