Ana Project

A open source judge for ACMers in Rust.

Requirements

• Rust toolchain (Edition 2018 or higher)
• libseccomp

Build Dependence:

• Protobuf (protobuf-compiler)

• Clang

• CMake

Usage

Run

cargo run

Run Ana on the localhost with the default configuration.

Root permission is needed.

Run cargo run -- --help for more information.

Test

cargo test -- --test-threads=1

Testing Ana needs root permission to read and write to cgroups and implement some other functions.

If you find that the time usage is less than the time limit but the status is TLE, try again with less judge_threads.

Docker

It is highly recommended to run Ana in a Docker container. Start an Ana server in the background by following commands:
docker run --privileged -p 8800:8800 -d hr567/ana

For more information and see all supported options:
docker run --privileged hr567/ana --help

Client

Ana uses gRPC framework to communicate with the client. The protobuf file which has defined the data structures and services is located in src/rpc/rpc.proto.

There is a simple client implementation in tests/common.
