In this paper, we propose an effective load balancing algorithm for DHT-Based P2P systems. Our main contributions are: (1) we propose an fully distributed mechanism to maintain the history of file access information. This information is used to predict the future file access frequencies and support the load distribution and redistribution operations; (2) we design a novel load balancing algorithm, which takes the file access history and peer heterogeneity properties into account to determine the load distribution. Our algorithm can generate the best load distribution decision when a new peer comes, it can also be able to dynamically perform the load redistribution during system running time if overloaded peers appeared. In our algorithm, no virtual servers are used, thus we have less processing overhead on the expensive routing metadata maintenance; (3) finally, we design a topologically-aware data replication mechanism, the topological information of the peers are used for file replication decisions. A file is replicated only on a peer close to the group of peers which have high access frequencies.","PeriodicalId":419226,"journal":{"name":"Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116359031","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}

In this environment, heterogeneous and globally distributed biodiversity-related resources such as data sets and analytical tools are made available to be accessed and assembled by users into workflows to perform complex scientific experiments. One such experiment is bioclimatic modelling of the geographical distribution of individual species using climate variables in order to predict past and future climate-related changes in species distribution. Data sources and analytical tools required for such analysis of species distribution are widely dispersed, available on heterogeneous platforms, present data in different formats and lack interoperability. The BDW system brings all these disparate units together so that the user can combine tools with little thought as to their availability, data formats and interoperability. We describe the architecture of the BDW problem solving environment (PSE) consisting of a number of components providing uniform access to heterogeneous resources and analytical tools. Architectural components of the BDW system include a workflow management tool, resource wrappers, a communications layer, BDW datatypes and a metadata repository.","PeriodicalId":419226,"journal":{"name":"Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124004328","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}

Dongarra","doi":"10.1109/CCGRID.2006.81","DOIUrl":"https://doi.org/10.1109/CCGRID.2006.81","url":null,"abstract":"With the increasing number of processors in modern HPC(High Performance Computing) systems, there are two emergent problems to solve. One is scalability, the other is fault tolerance. In our previous work, we extended the MPI specification on handling fault tolerance by specifying a systematic framework for the recovery methods, communicator, message modes etc. that define the behavior of MPI in case an error occurs. These extensions not only specify how the implementation of the MPI library and RTE (Run Time Environment) handle failures at the system level, but provide the normal HPC application developers with various recovery choices with varying performance and cost. In this paper, we continue the work on extending the MPI’s capability in this direction. Firstly, we are proposing an MPI operation level checkpoint/rollback library to recover the user’s data. More importantly, we argue that the future generation programming model of a fault tolerant MPI application should be recover-and-continue against the more traditional stop-and-restart model. Recover-and-continue means that in case an error occurs, we just re-spawn the failed processes. All the remaining living processes stay in their original processors mapping on memory. The main benefits of recover-and-continue are much less cost for system recovery and the opportunity of employing in-memory checkpoint/ rollback techniques. Compared with stable or local disk techniques, which are the only choices for stop-andrestart, doubtlessly, the in-memory approach significantly reduces the performance penalty in checkpoint/rollback. Additionally, it makes it possible to establish a concurrent multiple level checkpoint/ rollback framework. With the progress of our work, a picture of the hierarchy of future generation fault tolerant HPC system will be gradually unveiled.","PeriodicalId":419226,"journal":{"name":"Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124193988","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}

Security is one aspect that needs to be made as simple as possible for end users. The ESP-Grid and DyVOSE projects at the National e-Science Centre (NeSC) at the University of Glasgow are investigating security technologies which will make the end-user experience of using the grid easier and more secure. In this paper, we outline how simplified (from the user experience) authentication and authorization of users are achieved through single usernames and passwords at users' home institutions. This infrastructure, which will be applied in the second year of the grid computing module part of the advanced MSc in Computing Science at the University of Glasgow, combines grid portal technology, the Internet2 Shibboleth Federated Access Control infrastructure, and the PERMS role-based access control technology. Through this infrastructure inter-institutional teaching can be supported where secure access to federated resources is made possible between sites. A key aspect of the work we describe here is the ability to support dynamic delegation of authority whereby local/remote administrators are able to dynamically assign meaningful privileges to remote/local users respectively in a trusted manner thus allowing for the dynamic establishment of virtual organizations with fine grained security at their heart.","PeriodicalId":419226,"journal":{"name":"Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129049526","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}

What's more, for the scale and openness of grid environment, cooperation often occurs among completely unknown entities, where traditional identity-based trust system obviously cannot work well for its restricted scalability and flexibility. In this paper, we propose a pre-evaluating set based trust model, which resorts to reputation mechanisms for trust establishment. The introduction of the pre-evaluating set is to track an entity's rating criteria, overcome the prevalent strangeness of grid entities. With this pre-evaluating set, we can reasonably filter out malicious ratings by examining inconsistency between ratings to this set and to real transactions, effectively tune a rater's bias to cater to the current evaluator's criteria by interpolation approach and scientifically weight a rater's rating in aggregation by the introduction of criteria coherent degree which describes the similarity between an entity's rating criteria and the current evaluator's.","PeriodicalId":419226,"journal":{"name":"Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132350277","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}

Solutions to complex problems may be developed using workflow tools such as Kepler that coordinate different interoperable services. The availability of this type of cyberinfrastructure suggests that new applications should be designed with the grid in mind, using service oriented architecture for interoperability and efficiency.
