Let's talk about judges.
I'm very interested in how judge works. Maybe there already exist some topic in this spacious forum, so I would appreciate some links.

On linux you can control resources (memory, cpu time, ...) available to the user by the ulimit. For example in bash you can write

Code: Select all

ulimit -t 47
./your_binary

to kill the process after 47 seconds of cpu time have been used.

For more info try man bash and search for the ulimit command.

Is there any free source code for judge server system available online? Or some online documentation / book on how to make one?
