HIGH PERFORMANCE COMPUTING, ISC HIGH PERFORMANCE 2019, Vol. 11501, pp. 271–290.

author keywords: Resilience; Silent data corruption; Pragma programming
TL;DR: The live vulnerability factor (LVF) is introduced, a new metric that quantifies any lack of end-to-end protection for a given data structure that lifts the data protection burden from application programmers allowing them to focus solely on algorithms and performance while resilience is specified and subsequently embedded into the code through the compiler/library and supported by the runtime system.
