While this keeps the cost of development low, it can lead to performance and flexibility tradeoffs that the application developer and deployer must make. In this paper, we use the Montage astronomical image mosaicking application as prototypical DAG-based workflow application to layout the development and deployment decisions for distributed applications. We discuss and explain the lack of simple (easy-to-use), scalable, and extensible distributed applications. We then introduce SAGA as a technology that permits the construction of abstractions that aid the development and execution of the applications, and thus addresses some of common shortcomings of traditional distributed applications development. We use Montage together with SAGA to examine how legacy applications can be made to run on distributed infrastructures, to see if our reasons are valid, and to compare potential new methods for creating distributed applications with existing technologies that are currently used. We demonstrate the ability to (i) scale-out and (ii) use different production infrastructure, while maintaining performance comparable to established systems. Our hope is that by demonstrating the simplicity of development along with other advantages (performance, scalability, extensibility, and infrastructure independence), this example will encourage others to think more broadly about how distributed applications are created and how new programming models such as Dryad can be supported in an infrastructure independent way, thus eventually leading to more applications that can seamlessly scale-out.","PeriodicalId":325840,"journal":{"name":"2009 Fifth IEEE International Conference on e-Science","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132080346","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, as more administrative privileges are exposed to end users, providers are required to deploy network security measures that present challenges to the network virtualization technologies that are needed to enable inter-cloud communication. This paper studies these challenges and proposes techniques to enable unmodified applications on resources across distinct clouds. The techniques are implemented in TinyViNe, an extension to ViNe, a virtual networking technology for distributed resources in different administrative domains. The results of evaluating TinyViNe on a WAN-based testbed across three sites are reported for a bioinformatics application (BLAST) and MPI benchmarks. The results confirm that TinyViNe enables cross-cloud computing while having little impact on application performance. TinyViNe also has auto-configuration and “download-and-run” capabilities for easy deployment by users who are not knowledgeable about networking.","PeriodicalId":325840,"journal":{"name":"2009 Fifth IEEE International Conference on e-Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131819671","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}

Unfortunately, certain limitations -- that the portlet can only view data managed directly by the portal and that document and data files are the only resource that can be browsed -- make these tools less valuable in many real-world collaborations. This paper describes a semantically-enhanced scientific resource library portlet that extends the traditional document library to enable interaction with multiple distributed repositories in the cloud and to broaden the set of resources that can be viewed beyond simple hierarchical document folder-files structure to include people, sensors, data streams and other complex digital entities and their relationships. Our technology is based on semantic content abstraction and context aggregation functionality supported by Tupelo, a semantic content middleware and is implemented as a portlet plugin to the Liferay-based CyberCollaboratory portal. We describe the architecture components and the browsing features currently implemented and present a water science use case in which users are able to share documents, raw sensor data streams, and derived virtual sensor data (rainfall) from distributed sources within the same semantic resource library.","PeriodicalId":325840,"journal":{"name":"2009 Fifth IEEE International Conference on e-Science","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128780093","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}

Analyzing and visualizing the results of these simulations as they are computed can lead not only to early insights but also to useful knowledge that can be provided as feedback to the simulation, avoiding unnecessary use of computing power. Our work is aimed at making advanced visualization tools available to scientists in a user-friendly, Web-based environment where they can be accessed anytime from anywhere. In the context of turbulent combustion for example, visualization is used to understand the coupling between turbulence and the turbulent mixing of scalars. Although isosurface generation is a useful technique in this scenario, computing and rendering isosurfaces one at a time is expensive and not particularly well-suited for such a Web-based framework. In this paper we propose the use of a summary structure, called contour tree, that captures the topological structure of a scalar field and guides the user in identifying useful isosurfaces. We have also designed an interface which has been integrated with a Web-based simulation monitoring system, that allows users to interact with and explore multiple isosurfaces.","PeriodicalId":325840,"journal":{"name":"2009 Fifth IEEE International Conference on e-Science","volume":"13 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120910931","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}

Predictions of future sequences in a phylogenetic tree are important for a variety of applications including drug discovery, pharmaceutical research and disease control. In this work, we predict future DNA sequences in a phylogenetic tree using cellular automata. Cellular automata are used for modeling neighbor-dependent mutations from an ancestor to a progeny in a branch of the phylogenetic tree. Since the number of possible ways of transformations from an ancestor to a progeny is huge, we use computational grids and middleware techniques to explore the large number of cellular automata rules used for the mutations. We use the popular and recurring neighbor-based transitions or mutations to predict the progeny sequences in the phylogenetic tree. We performed predictions for three types of sequences, namely, triose phosphate isomerase, pyruvate kinase, and polyketide synthase sequences, by obtaining cellular automata rules on a grid consisting of 29 machines in 4 clusters located in 4 countries, and compared the predictions of the sequences using our method with predictions by random methods. We found that in all cases, our method gave about 40% better predictions than the random methods.","PeriodicalId":325840,"journal":{"name":"2009 Fifth IEEE International Conference on e-Science","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124520791","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}
