Much recent research has attempted to determine the benefits and drawbacks of cloud computing for scientific applications. Although clouds have many attractive features, such as virtualization, on-demand provisioning, and “pay as you go” usage-based pricing, it is not clear whether they are able to deliver the performance required for scientific applications at a reasonable price. In this paper we examine the performance and cost of clouds from the perspective of scientific workflow applications. We use three characteristic workflows to compare the performance of a commercial cloud with that of a typical HPC system, and we analyze the various costs associated with running those workflows in the cloud. We find that the performance of clouds is not unreasonable given the hardware resources provided, and that performance comparable to HPC systems can be achieved given similar resources. We also find that the cost of running workflows on a commercial cloud can be reduced by storing data in the cloud rather than transferring it from outside.","PeriodicalId":416133,"journal":{"name":"2009 5th IEEE International Conference on E-Science Workshops","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132558585","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}

Up to now research in the security area concentrates on authentication and authorization on the resources themselves, but to enhance network security more generally, access control must be pushed back to the entry point of the resource providers' network. In this paper TCP-AuthN is presented, an approach for dynamic firewall operation, which uses the TCP three-way handshake to transport users' authentication information for dynamic firewall operation. The authentication information enables firewalls to authorize each connection establishment individually, based on the user's proven identity. To prevent man-in-the-middle attacks and replay attacks, a challenge-response procedure must be accomplished before the connection is finally allowed. To distinguish the authentication information from application level data, a new TCP option tcpauthn was designed. The presented approach is intended to withdraw the initial authorization decision from the resources and therefore from the internal network and move this decision to firewalls, which are employed to protect networks and services.","PeriodicalId":416133,"journal":{"name":"2009 5th IEEE International Conference on E-Science Workshops","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130000051","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}

Mapping the correlations between categories of genre, date, and location as assessed in relation to records in a spatial database consisting of over 1700 Merseyside films, we examine ways in which cartographic readings of film texts and practices can illuminate historical understandings of urban and regional place-making. Reflecting broader theoretical trends, a growth of interest in cartographic methods in recent historical studies on film is indicative of an emergent ‘spatial turn’ in social science and humanities research. Responding to these developments, we argue that digital and geospatial resources such as those offered by GIS technology enable researchers to: (1) ‘navigate’ the spatial histories attached to landscapes in film; (2) develop new frameworks of analytical enquiry in relation to film, place and memory; and (3) to re-think and reformulate some of the questions critically addressing the ‘place’ of archival images of cities in discourses of cultural memory, regeneration, and urban place-making.","PeriodicalId":416133,"journal":{"name":"2009 5th IEEE International Conference on E-Science Workshops","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128847831","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}
