Overview

The Cross-layer Application-Aware Resilience at Extreme Scale (CAARES) project, a collaborative effort between ICL, Rutgers University, and Stony Brook, aims to provide a theoretical foundation for multi-level fault management techniques and provide a clear understanding of existing obstacles that could obstruct generic and efficient approaches for fault management at scale. This effort is vital for large-scale science, because, as extreme-scale computational power enables new and important discoveries across all science domains, the current understanding of fault rates is casting a grim shadow and revealing a future where failures are not exceptions but are the norm.

By studying combinations of fault tolerance techniques instead of studying them in isolation from each other, CAARES seizes the opportunity to identify moldable techniques at the frontier of known approaches and highlight a composition of methodologies that inherit their individual benefits but do not exhibit their drawbacks, leading to the development of resilience techniques able to bridge the gap between fault tolerance ergonomics and efficiency.
