While enterprise grids exist within organizations, national grids have become common, usually consisting of government as well as academic facilities. Such facilities are not uncommonly lenient with blanket policies to allow inbound and outbound grid traffic. This is far from ideal, from a security perspective, but given the dynamic nature of grid use, it is impractical to keep restrictive firewalls and manually keep up with on-demand firewall reconfiguration. Other solutions are necessary, where security is not sacrificed. Apart from first generation solutions that were mostly not sufficiently generic, standardization work is now ongoing, but exclusively aimed at firewall virtualization. We argue for an architectural solution that encompasses firewall virtualization as well as other methods that can be more appropriate in many environments. This paper describes our notion of the missing layer between grid and fabric, which we refer to as the virtual connectivity layer. We have developed two implementations within this layer and discuss how they fit into a complete and well-defined architectural solution.","PeriodicalId":325840,"journal":{"name":"2009 Fifth IEEE International Conference on e-Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121637294","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}

By using computational steering, users can dynamically control their simulations or computations to reach expected results more efficiently. The framework supports steerable applications by introducing an asynchronous iterative MapReduce programming model that is deployed using Hadoop over a set of virtual machines executing on a multi-cluster grid. To tolerate the heterogeneity between different sites, results are collected asynchronously and users can dynamically interact with their computations to adjust the area of interest. According to users' dynamic interaction, the framework can redistribute the computational overload between the heterogeneous sites and explore the user's interest area by using more powerful sites when possible. With our framework, the bottleneck induced by synchronisation between different sites is considerably avoided, and therefore the response to users' interaction is satisfied more efficiently. We illustrate and evaluate this framework with a scientific application that aims to fit models of the Milky Way galaxy structure to stars observed by the Sloan Digital Sky Survey.","PeriodicalId":325840,"journal":{"name":"2009 Fifth IEEE International Conference on e-Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114617575","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}

File format conversion is a necessary part of data dissemination and curation. Complete and robust converters however are hard to find and build due to the abundance of file formats, the fact that many formats are closed, and the complexities within individual format specifications. On the other hand many software applications exist that are capable of performing some degree of data conversion between a subset of the available formats. To take advantage of this we introduce a data structure called an I/O-Graph to store the available input and output formats of these applications. Based on a concept of textit{textbf{imposed code reuse}} we use this to develop a service, NCSA Polyglot, which through this graph is capable of performing the larger union of conversions supported by the underlying software. The Polyglot system is designed to be easily extensible, scalable with the number of conversion requests, and inclusive of all available third party software. Given a data set of files from a particular domain, we are able to assign weights to the edges within the I/O-Graph indicating the amount of information retained during a conversion. These edge weights allow the system to then choose conversion paths with the least amount of information loss.","PeriodicalId":325840,"journal":{"name":"2009 Fifth IEEE International Conference on e-Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131606349","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}
