Improving Multi-Core System Dependability with Asymmetrically Reliable Cores

Peter David Ungsunan, Chuang Lin, Yi Gai, Xiangzhen Kong
2009 2009 International Conference on Complex, Intelligent and Software Intensive Systems  
We show that by using asymmetrically reliable cores the overall system failure rate can be reduced by several times when critical processes can be isolated and executed by higher reliability cores, while  ...  Critical and non-critical software components are identified and matched with the higher reliability cores.  ...  A software approach is for programmers to write fault tolerant software that does not require high reliability. We use both hardware and software techniques to improve system dependability.  ...

Critical Systems Heuristics [chapter]

Werner Ulrich, Martin Reynolds
2010 Systems Approaches to Managing Change: A Practical Guide  
The methodological core idea is that all problem definitions, proposals for improvement, and evaluations of outcomes depend on prior judgments about the relevant whole system to be looked at.  ...  Improvement, for instance, is an eminently systemic concept, for unless it is defined with reference to the entire relevant system, suboptimisation will occur.  ...

Critical Components Identification for Service-Oriented Systems

Xiuguo Zhang, Shuo Jiang, Xinghao Qiao, Zhiying Cao, Liangjun Zhang
2019 Symmetry  
Identifying critical components are of great significance to the overall reliability of service-oriented systems (SOSs).  ...  Then, an improved weighted LeaderRank algorithm (IW-LeaderRank) is proposed to measure the importance of components and obtain the sequence of critical components.  ...  For example, in Figure 3 , users enter the system to register and login, and the system executes service 'register' and service 'login'.  ...

Locality vs. criticality

Roy Dz-ching Ju, Alvin R. Lebeck, Chris Wilkerson, Srikanth T. Srinivasan
2001 Proceedings of the 28th annual international symposium on Computer architecture - ISCA '01  
This leads to a potential mis-match between load latency requirements and latencies realized using a traditional memory system. To bridge this gap, we partition loads as critical and non-critical.  ...  Although criticality-based prefetching can help for some resource constrained programs, its benefit over locality-based prefetching is small and may not be worth the added complexity.  ...  We thank the anonymous reviewers and Steve Reinhardt for comments and suggestions on this work.  ...
