Autograder

We use Gradescope’s autograding system to build and run your submissions. The autograder will build all projects using gcc (not clang). You should assume much of the C++20 standard is supported by our grading infrastucture. We are using gcc version 13.1, for more information on which features are supported look at C++ 20 Support in GCC.

Software configuration

The autograder is running Ubuntu 22.04, with the following software:

• openjdk: 11.0.28
• Python: 3.10.12
• gcc/g++: 13.1
• GNU Make: 4.3
• CMake: 3.22.1
• ANTLR4: 4.10.1

Please make sure your submission is compatible with these versions, and that all other dependencies are self-contained in the project. If you are planning to use a dependency not listed which cannot be installed via apt or pip3 in ./build.sh, please contact the course staff.

The grading server will have network access when running tests, so you can download and install packages while running ./build.sh. However, please do this responsibly, and avoid using network access in ./run.sh.

Hardware configuration

The autograder will have at least one virtual CPU core and 1.5 GB of memory. Autograder runs will timeout automatically after 40 minutes.
