Feature Request: Support for Parallel Case Execution

[schmoelder]

Currently, CADET-RDM restricts users to running only one case at a time because all results are stored and committed in a single output repository directory. This limitation prevents parallel execution of multiple cases (e.g., parameter sweeps or independent scenarios), which is often desirable for efficiency.

Proposed Solutions:

1. Multiple Repository Clones:
   Clone the output repository multiple times to isolate parallel runs.
   Downside: Risk of desynchronization (e.g., if push=False), requiring manual conflict resolution.

2. Temporary Directory + Post-Run Commit:

   • Let CADET-RDM create temporary directory to store results during execution.
   • Copy and commit results to the output repository after completion.
   • Challenge: How do we communicate which temp directory is relevant for which "runner"?

3. Configurable Output Directory:
   Allow users to specify a custom directory for CADET-RDM to track and commit results.
   Question: Are there downsides to this approach (e.g., complexity, edge cases)?

Intuitively, I would go with option 3.
