Data is being collected by researchers regarding the mass of the ice creating large amounts of data which can be overwhelming to undergraduate and K-12 researchers. Visualization can lead to a better understanding of this data and guide students to involvement in polar research. The goal of this project was the implementation of code to provide an interactive display of ice depth data from Greenland expeditions. The project required the cooperation of the CReSIS and PolarGrid partnerships. The implementation involved the use of a social networking site as a gateway to ice depth data. This project is the basis of a cyberinfrastructure gateway to be implemented at ECSU using an intermediary shared services approach versus the previous generation of component based portals.","PeriodicalId":257555,"journal":{"name":"TeraGrid Conference","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125852678","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}

To expand the accessibility to the lustre filesystem, we also include our efforts towards cross-realm authentication and integration of Lustre 2.0 with the kerberos-enabled NFS4.","PeriodicalId":257555,"journal":{"name":"TeraGrid Conference","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132237901","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 complexity of programming multicore systems underscores the need for powerful and efficient runtime systems that manage resources such as threads and communication sub-systems on behalf of the applications.\u0000 In this paper, we study several multicore performance issues on clusters using Intel, AMD and IBM processors in the context of the Charm++ runtime system. We then present the optimization techniques that overcome these performance issues. The techniques presented are general enough to apply to other runtime systems as well. We demonstrate the benefits of these optimizations through both synthetic benchmarks and production quality applications including NAMD and ChaNGa on several popular multicore platforms. We demonstrate performance improvement of NAMD and ChaNGa by about 20% and 10%, respectively.","PeriodicalId":257555,"journal":{"name":"TeraGrid Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125847593","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}

CI has experienced rapid progress in enabling technologies -- hardware, storage, networking, middleware, tools, libraries -- but much slower improvements in workforce development. Currently, CI consumers tend to lag substantially behind CI capabilities.
