However, the computation required can be expensive, particularly if it has to be performed multiple times, for example to determine optimal system parameters. We present efficient incremental techniques for quantitative verification of Markov decision processes, which are able to re-use results from previous verification runs, based on a decomposition of the model into its strongly connected components (SCCs). We also show how this SCC-based approach can be further optimised to improve verification speed and how it can be combined with symbolic data structures to offer better scalability. We illustrate the effectiveness of the approach on a selection of large case studies.","PeriodicalId":233608,"journal":{"name":"2011 IEEE/IFIP 41st International Conference on Dependable Systems & Networks (DSN)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123657627","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}

For service providers who make significant investments in new virtualized data centers in support of private or public clouds, one of the serious challenges is the problem of recovering costs for new server hardware, software, network, storage, management, etc. Gaining visibility and accurately determining the cost of shared resources used by collocated services is essential for implementing a proper chargeback approach in cloud environments. We introduce and compare three different models for apportioning cost and champion the one that is least sensitive to workload placement decisions and provides the most robust and repeatable cost estimates. A detailed study involving 312 workloads from an HP customer environment demonstrates the result. Finally, we employ the cost model in a case study that evaluates the impact on the cost of exploiting different virtualization platform alternatives for the 312 workloads. For example, some workloads may cost more to host using certain virtualization platforms than on others or on standalone hosts. We demonstrate different decision points with potential cost savings of nearly 20% by “right-virtualizing” the workloads.","PeriodicalId":233608,"journal":{"name":"2011 IEEE/IFIP 41st International Conference on Dependable Systems & Networks (DSN)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124715476","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, due to an ever increasing system complexity, use of commercial-off-the-shelf components, virtualization, ongoing system patches and updates and dynamicity such approaches have become difficult to apply. Therefore, a new area in dependability research has emerged focusing on proactive approaches that start acting before a problem arises in order to increase time-to-failure and/or reduce time-to-repair. These techniques frequently build on the anticipation of upcoming problems based on runtime monitoring. Industry and academia use several terms for such techniques, each focusing on different aspects, including self-* computing, autonomic computing, proactive fault management, trustworthy computing, software rejuvenation, or preventive/proactive maintenance.","PeriodicalId":233608,"journal":{"name":"2011 IEEE/IFIP 41st International Conference on Dependable Systems & Networks (DSN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115420069","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}

We demonstrate the utility of CCE by building a new journaling mode within the Linux ext3 file system. When mounted in this discreet mode, ext3 uses CCEs to ensure that writes are properly ordered and thus maintains file system integrity despite the presence of an improperly behaving disk. We show that discreet mode journaling operates with acceptable overheads for most workloads.","PeriodicalId":233608,"journal":{"name":"2011 IEEE/IFIP 41st International Conference on Dependable Systems & Networks (DSN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130582590","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}

The goals of HotDep are to bring forth cutting-edge research ideas spanning the various domains of dependable systems, and to build linkages between two communities with active interest in dependability research, namely researchers who attend traditional dependability conferences such as DSN and ISSRE, and those who attend mainstream systems conferences such as SOSP, OSDI, and EuroSys. To achieve these goals, the workshop has been alternating between a dependability conference in odd years and a systems conference in even years. This year, we have kept the tradition of previous meetings by selecting a program committee with a mix of researchers from both communities: • Lorenzo Alvisi, University of Texas at Austin • Remzi Arpaci-Dusseau, University of Wisconsin, Madison • Byung-Gon Chun, Intel Labs Berkeley • Arun Iyengar, IBM Research • Mohamed Kaâniche, LAAS-CNRS • Daniel Mossé, University of Pittsburgh • Priya Narasimhan, Intel Labs/Carnegie Mellon University • James Plank, University of Tennessee • André Schiper, EPFL • Alexander Shraer, Yahoo!

In addition to the impact on today computerized systems, nanocomputing is an essential lever to foster the emerging cyberphysical system paradigm. However, the dependability and security of these unprecedentedly small devices, of their deployment, and of their interconnection remain uncertain. The main sources of concern are: • Nanometer devices are expected to be highly sensitive to process variations. The guard-bands used today for avoiding the impact of such variations will not represent a feasible solution in the future. As a consequence, timing errors and their higher frequency of occurrence have to be addressed. • New and intricate failure modes, specific to new materials, are expected to raise serious challenges to the design and test engineers. • Environment induced errors, such as single event upsets (SEU), are likely to occur more frequently than in the case of more conventional semiconductor devices. • Design of hardware architectures encompassing resilience techniques are needed to achieve the development of highly reliable energy efficient systems. • The increased complexity of the systems based on nanotechnology will require improved computer aided design (CAD) tools, as well as better validation techniques. • The security of nanocomputing systems may be threatened by malicious attacks targeting new vulnerable areas in the hardware.","PeriodicalId":233608,"journal":{"name":"2011 IEEE/IFIP 41st International Conference on Dependable Systems & Networks (DSN)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116608481","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}

We often need to change the specification and implementation of a system due to the changes of environments and users' requirements.
