due to the Nomad request exiting before the allocation is stopped. We catch this behavior by introducing a time period for the allocation being stopped iff the exit code is 128.
Poseidon
Poseidon provides containerized execution of arbitrary user code inside a Docker container for learning purposes. It has two main purposes:
- Securing the executions so that they are isolated from each other and from the host system.
- Being scalable enough to provide hundreds of executions per minute.
Poseidon also offers a live I/O connection to the running program via WebSocket.
Poseidon is designed to be used with CodeOcean, a code-execution provider and auto-grader used in MOOC platforms.
Poseidon requires a Nomad cluster for scheduling its executions, which needs to be set up separately.
