Description

When running regressions there can be ~45k jobs that are run as part of the regression. It can be a bit of a pain if the regression fails due to some intermittent external issue. Being able to retry failed jobs or restart a killed regression run would be nice.

- [ ] Store enough information to disk about the regression run being started
- [ ] Store metadata about the planned jobs up front
- [ ] Store the scheduler state, or enough information about the progress of the regression run so that it can be restored if killed mid run.
- [ ] Add the ability to continued a killed regression run
- [ ] Add the ability to retry failed jobs - this could be useful if the issue is due to resource dependent timeouts.

Research direction

Start by locating DVSim’s Python entry points for regression runs and the scheduler state; no files or tests are named in the issue. Map what metadata and progress must be preserved before defining verification, with restoration of a killed run and retrying failed jobs as the completion checks.
