|
* Added a max failure for tasks. If tasks fail more times, they get cancelled
* Added maxNumFailures to the frontend
* Updated tests
|
|
* Updated the checkpointing system to use SimTrace. The checkpoint model can now also scale, which means the interval between checkpoints can increase or decrease over time.

|
|
* Started on reimplementing the SimTrace implementation
* updated trace format. Fragments now do not have a deadline, but a duration. The Fragments are executed in order.
