Dear StarPU developers,
I hope you are doing well.
I am working on some fault tolerance strategies for task-based
applications. During the execution, halfway in the DAG,
a task may be corrupted, i.e., produce invalid result for some reasons.
One way to solve the problem is simply re-executing the task. But
this will require input data from predecessors which may in their turn
need input from their predecessors. At the end one may need to re-execute
a portion of the DAG. To achieve this, I have a few questions:
- With StarPU how can a node traverse backward a part of the DAG?
- Is it possible for a node to insert subtasks during the computation?
- How to inform the neighbouring nodes on the new subtasks?
Best regards,
--Mawussi
