Title:System Support for Improving Software Dependability During
Production Runs Author(s):Qin, Feng Subject(s):computer science
Abstract:As hardware performance and dependability have
dramatically improved in the past few decades, the software
dependability issues are becoming increasingly important.
Unfortunately, many studies show that software bugs, which
inevitably slip through various bug detection methods and even
the strictest testing before releasing, can greatly affect
software dependability during production runs. To improve
software dependability during production runs, this dissertation
proposes to address software bugs at multiple levels by
leveraging support from the underlying hardware, the OS kernel,
and the middle-layer runtime. The proposed multi-level defenses
address software bugs and their effects at different stages of
program execution. The first-level defense detec
