Resilience Research Questions

The main question is where does resilience fit into the X-stack runtime abstract architecture, with guiding questions being:

1) What features of other levels of the stack (algorithm, programming model, compiler, runtime, and hardware) should resilience depend on?

2) How can resilience schemes best exploit application, runtime, or programming model semantics?

3) What are the biggest missing pieces needed from the various layers to make resilience schemes succeed?

4) What is the impact on resilience of the wide range of expected operating scenarios with respect to dynamically changing resources, application characteristics, and the wide range of possible error and failure rates?

Please add your comments (with you name) after each question.
