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. :roll:
I wonder how does he stop the program when TLE, how are MLE & OLE measured and so on... :o

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.
