ABSTRACT:
Resilience is a big challenge in future exascale machines.
Existing approaches are unlikely to address complex failures like latent errors, therefore we need a new approach.
We propose Global View Resilience (GVR), a new library that exploits a global view data model and adds reliability through versioning (multi-version), user control timing and rate (multi-stream), and flexible cross layer error signalling and recovery. GVR enables application programmers to exploit deep scientific and application code insights to manage resilience (and its overhead) in a flexible, portable fashion.
We applied the GVR library to several existing scientific application codes and showed that GVR can be easily applied and runtime overhead for versioning is negligible.
