Is there any tools to limit execution time and memory consumption of a program ?
By pastglory1, 4 years ago, In English

Hello, I'm Exile_2k4.

Now, I really want to know if there is any tools (script, Windows CMD command, or something else) that can be used to limit execution time and memory consumption. In example, a CMD script that set the time limit of a process to 5 seconds and allows 256MB of memory (which is used by the task), and after 5 seconds, or exceeded the memory limit, if the task is still running, then kill it.

Just like what Codeforces, or any Online Judge do, but more portable.

Do you have any ideas ? My OS is Windows 10 (not Linux).

Thank you.

Use Windows Subsystem for Linux.

There are many tutorials for installation.

      link

      Just follow the simple instructions.

      And copy your code into the Linux Distribution's folder, and run it with

      timeout 5 {Your_Programs_Name}

      (Sorry, I don't know how to adjust with memory limit)

      But you can use command

      size {Your_Programs_Name}

      to see your program's static memory usage.

      I am not familiar with Windows tools, but process-governor looks interesting.

      As FlameSlayer has mentioned, isolate is the answer for Linux. Building and installing are simple (install dependencies, make and make install) and it has been battle-tested in multiple IOI's. However, as it uses Linux-specific mechanisms it's not expected to run on Unix or native Windows (WSL may be a chance but I have not attempted).

      FYI, if not building a judge system with safety in mind, it is also possible to write a program to limit resource usage under Unix-like systems. If interested, look into the function setrlimit() (see the manual page, and there are also examples online).

      Hope it helps!

There are runners for Windows, but they require complex setup. You can see the VOJ's implementation here You need some Java and C++ skills, and you need to understand Chinese.

here is a compiled CMD version.
