Parallel computing workers overwrite each other files in optimization

Hello everybody, I am trying to optimize a function, the function do the following steps:
- get the parameters from the optimizer
- write the parameters to a file
- recall another program to do the simulation
- load the the result file to matlab
- calculate the objective function for the optimizer.
The problem is when matlab do this process simultaneously in parallel optimization, the files keep overwriting each other, I tried to make a different folder for each worker and put all of files in each folders but then I don't know how to put different objective functions in this folders, because objective function m-file must be in same folder with other files to make the simulation happen!? I will be very appreciated if you give me some ideas, thank you very much.

I don't see why it should. Can't you specify paths when saving files?
