As these machines grow in scale, faults become more frequent and system complexity makes it difficult to detect and to diagnose them. The difficulty is particularly large for faults that degrade system performance or cause erratic behavior but do not cause outright crashes. The cost of these errors is high since they significantly reduce system productivity, both initially and by time required to resolve them. Current system management techniques do not work well since they require manual examination of system behavior and do not identify root causes. When a fault is manifested, system administrators need timely notification about the type of fault, the time period in which it occurred and the processor on which it originated. Statistical modeling approaches can accurately characterize normal and abnormal system behavior. However, the complex effects of system faults are less amenable to these techniques. This paper demonstrates that the complexity of system faults makes traditional classification and clustering algorithms inadequate for characterizing them. We design novel techniques that combine classification algorithms with information on the abnormality of application behavior to improve detection and characterization accuracy significantly. Our experiments demonstrate that our techniques can detect and characterize faults with 85% accuracy, compared to just 12% accuracy for direct applications of traditional techniques.","PeriodicalId":236791,"journal":{"name":"IEEE/IFIP International Conference on Dependable Systems and Networks (DSN 2012)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114954299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the design has inherent performance implications which were not easy to overcome. Until now the context switching and kernel involvement in the message passing was the performance bottleneck for such systems to get broader acceptance beyond niche domains. In contrast to other areas of software development where fitting the software to the parallelism is difficult, the new multicore hardware is a great match for the multiserver systems. We can run individual servers on different cores. This opens more room for further decomposition of the existing servers and thus improving dependability and live-updatability. We discuss in general the implications for the multiserver systems design and cover in detail the implementation and evaluation of a more dependable networking stack. We split the single stack into multiple servers which run on dedicated cores and communicate without kernel involvement. We think that the performance problems that have dogged multiserver operating systems since their inception should be reconsidered: it is possible to make multiserver systems fast on multicores.","PeriodicalId":236791,"journal":{"name":"IEEE/IFIP International Conference on Dependable Systems and Networks (DSN 2012)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129198123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Commodity systems must be made resilient to these in-field faults through very low-cost resiliency solutions. Software-level symptom detection techniques have emerged as promising low-cost and effective solutions. While the current user-visible Silent Data Corruption (SDC) rates for these techniques is relatively low, eliminating or significantly lowering the SDC rate is crucial for these solutions to become practically successful. Identifying and understanding program sections that cause SDCs is crucial to reducing (or eliminating) SDCs in a cost effective manner. This paper provides a detailed analysis of code sections that produce over 90% of SDCs for six applications we studied. This analysis facilitated the development of program-level detectors that catch errors in quantities that are either accumulated or active for a long duration, amortizing the detection costs. These low-cost detectors significantly reduce the dependency on redundancy-based techniques and provide more practical and flexible choice points on the performance vs. reliability trade-off curve. For example, for an average of 90%, 99%, or 100% reduction of the baseline SDC rate, the average execution overheads of our approach versus redundancy alone are respectively 12% vs. 30%, 19% vs. 43%, and 27% vs. 51%.","PeriodicalId":236791,"journal":{"name":"IEEE/IFIP International Conference on Dependable Systems and Networks (DSN 2012)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132130404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
