Hi,
I am using the optimization toolbox with a relatively complicated computational fluid dynamics tool I have written as the objective function. The tool uses global variables within it becuase it was convenient when I wrote it. Some of these variables are simulation specific and will change based on the optimization input.
My question is, when I use the ga tool in parallel, is there a risk of the global variables becoming confused because simultaneous simulations are being performed on different processors? Or will the global variables be kept private to each processor?
Thank you,
W. S. H.
UPDATE:
Instead of spending excessive time trying to figure out what was going on with my problems, I spent a couple hours modifying my tool to use only private variables. This fixed the issues I was having. So not sure what the problem was in my case, but the lesson here is be VERY CAREFUL if trying to use global variables in this type of problem.
