Grader (Gabriel)¶
Configuration¶
Install SBT on your Operating System.
First copy default configuration in “src/main/resources/conf” directory: - application_default.conf -> application.conf
Gabriel need to connect to Sealtiel to fetch grading requests. You need to configure the parameter in “src/main/resources/conf/application.conf” file.
Gabriel need to connect to Sandalphon to fetch problem evaluator files (testcases, subtask configuration, constraints, checkers, etc). You need to configure the parameter in “src/main/resources/conf/application.conf” file.
Next, you have to configure Moe. Run ./configure and make in judgels-moe repository. Gabriel uses Moe to grade submissions. You need to configure the parameter in “src/main/resources/conf/application.conf” file.
Gabriel depends on judgels-moe and judgels-gabriel-commons to run, make sure they are on the same level of directory with Gabriel.
Running Gabriel¶
You can run Gabriel by using “sbt” command to enter sbt console and enter “run” command in the console.
Grading Engine¶
Gabriel can grade types of submissions based on existing grading engines. Currently there are three grading engines as described on Problem Types:
- Batch
- Batch with Subtasks
- Interactive with Subtasks
Future Target¶
Currently Gabriel’s grading engine are coded along with Gabriel. In the future, Gabriel’s grading engine are supposed to be separated as add-on that can be fetch by Gabriel.
