Evaluating the Error Resilience of Parallel Programs

Bo Fang, Karthik Pattabiraman, Matei Ripeanu, Sudhanva Gurumurthi
2014 2014 44th Annual IEEE/IFIP International Conference on Dependable Systems and Networks  
In this paper, we propose a methodology to characterize the resilience of OpenMP programs using fault-injection experiments.  ...  We find that the error resilience of OpenMP applications depends on the program structure and thread model; hence, these need to be taken into account while characterizing error resilience.  ...  We collect the necessary dynamic information from a program at runtime to obtain the execution profile of each of its OpenMP threads, thus addressing challenge 1.  ...

Detecting Java Theft Based on Static API Trace Birthmark [chapter]

Heewan Park, Seokwoo Choi, Hyun-il Lim, Taisook Han
2008 Lecture Notes in Computer Science  
Because the API traces are extracted by static analysis, they can be applied to library programs which earlier dynamic birthmarks cannot handle properly.  ...  Because the API traces can reflect the behavior of a program, our birthmark is more resilient than the existing static birthmarks.  ...  Dynamic birthmarks are known to be more resilient to program transformations such as code obfuscation than static birthmarks.  ...

2014 Proceedings of the National Academy of Sciences of the United States of America  
Given that resilience is fast becoming a distinct policy objective, we need a clear theory of development resilience to guide measurement and programming and to inform evaluation.  ...  The conceptualization we advance for development resilience focuses on the stochastic dynamics of individual and collective human well-being, especially on the avoidance of and escape from chronic poverty  ...  Toward Development Programming to Build Resilience Several programming implications emerge from this framing of the dynamics of well-being.  ...
