comment Will SGE output slow down my simulation, if so, how much?
That's exactly my question, I am curious to know what happens if this file grows into a big file like 2G big. How did the *nix system write into this file, by some fopen command as in C++, or doing some append command, which might be keep writing in a certain storage address? Or what? I think if no open and close repeating operations then it would be not slow. Because the file is really big, I am not sure if linux, ext system like windows has some file size limitations.......

"my guess is that it's a line every so many steps", no, it writes around 20 lines every time step. "Also, if you are worried about the size of the file, I'm sure your simulation package will have an option to reduce the frequency of writing the log.", okay, this I will try, but I'd really hope this could be solved on SGE or system's side, not on the original code.
