By writing code to use separate log files?

I'm not sure where you have problems. You didn't post any code that shows the problem and it seems to me that you are simply continuing a series of fruitless posts of sandy1028 who seems to expect to get his/her code written by us. This is not how this site works. If you want to write a program that runs multiple instances of itself in parallel, you will have to learn how to program first. Generating multiple log file names is not hard.
