Reliability and performance are both influenced by the topology type of the underlying network. Fully connected networks for example provide better performance, the number of links however increases the cost of the system. In this paper, we considered these three factors, namely performance, reliability and cost, simulating performance for different network topologies and different reliability thresholds. The simulation results demonstrate that 1) regular topologies behave better than irregular topologies, and 2) the topology of the network is more influential to performance than the actual number of physical links.","PeriodicalId":259447,"journal":{"name":"2008 IEEE 17th Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises","volume":"94 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120904051","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 problem of these systems is that they do not take into account resource's quality in their fairness measure. Resource quality is an important factor to obtain fair allocations. When this factor is not kept in mind, high quality peers can obtain low quality resources, bringing the system to an unfair state. In this work we present a generic resource allocation system that improves the system fairness in the presence of quality heterogeneity. With low network overhead, our system provide near complete allocation while maintaining network stability and fairness.","PeriodicalId":259447,"journal":{"name":"2008 IEEE 17th Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122932770","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, the grid and the grid applications development are still far from being affirmed, which is mainly due to the undeveloped grid-enabled computing environments. For that reason in this paper we propose a toolbox, called GrIPLab 1.0 (Grid Image Processing Laboratory), that aims at providing high performance image-processing platform in a grid computing environment by using the GLite middleware developed in the EGEE project. GrIPLab 1.0 is a combination of vision algorithms (the most common and some novel approaches) on which complex distributed vision applications can be modeled as a simple sequence of choices in a user friendly interface. Therefore, the main advantage of the presented dynamic grid toolbox is that provides a novel and comfortable access for scientific software developers and users without prior knowledge of grid technologies or even the underlying architecture. In this paper, we discuss the infrastructure that provides flexible and useful mechanism to achieve series image processing operations and we analyze the advantages of using such a system.","PeriodicalId":259447,"journal":{"name":"2008 IEEE 17th Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114218707","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}

Economics inspired models have shown ability to handle efficiently the allocation of resources and services, scaling up well as they are decentralized. Our model considers the arbitration of decisions at the local scope and short term, the regulation of the system at global scope, and the sharing of information between global and local environments. This paper presents a scalable model and evaluates by simulation a system where global market information circulates in aggregated and scalable form, the rate of demand by participants is globally regulated by a currency mechanism, preference is regulated by a reputation mechanism, and local regulation among competing participants is resolved by auction mechanisms. The paper shows how scalable systems benefit from distributed marketplaces supporting global information flow to regulate and optimize local and global behavior.","PeriodicalId":259447,"journal":{"name":"2008 IEEE 17th Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124759035","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}

Such a new scenario calls for powerful strategies able to guarantee stringent QoS requirements in order to meet SLAs between customers and provider. For this reason, it is necessary to analyze and predict performance with respect to different load conditions or management strategies. In this paper, we present a methodology to analyze performance in gLite Grids through the use of Generalized Stochastic Petri Nets (GSPNs). We will present a cluster-level model of a typical gLite site taking into account the coexistence between normal and MPI-based jobs.We will investigate the influence of different strategies (e.g., scheduling) on the performance of the whole site highlighting aspects related to both customer and provider point-of-views.","PeriodicalId":259447,"journal":{"name":"2008 IEEE 17th Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises","volume":"323 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122628436","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 underpinning for an organization's use of SOC techniques is the ability to discover and compose Web services. Leading industry approaches rely heavily on syntactical approaches for managing service-based business processes. As such, these approaches are limited since the true functionality of ambiguous capabilities (i.e. web service operations) cannot be inferred. We introduce approaches that disambiguate services by interleaving process-based control with semantic annotations. In this paper, we introduce a generalized architecture where intelligent software agents control process-oriented composition that leverages the descriptiveness of semantics. An outcome of this work is the specification of a multiple agent system where a query agent interacts with multiple repository agents to perform business-oriented service composition.","PeriodicalId":259447,"journal":{"name":"2008 IEEE 17th Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116087693","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 such challenging situations, processes should be adapted in order to cope with anomalous situations, including connection anomalies and task faults. This requires the provision of intelligent support for the planning and enactment of complex processes, that allows to capture the knowledge about the dynamic context of a process. In this paper, we show how this knowledge, together with information about the capabilities of the available actors, may be specified and used to not only to support the selection of an appropriate set of agents to fill the roles in a given task, but also to solve the problem of adaptivity. The paper describes a first prototype of a PMS based on well-known artificial intelligence techniques and how it can be extended to tackle adaptation.","PeriodicalId":259447,"journal":{"name":"2008 IEEE 17th Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128685972","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}

While MASs (Multi-Agent Systems) provide for a principled approach to pervasive intelligent systems, large scale and physical distribution call for expressive coordination models and technologies promoting distribution of intelligence. Also, the issue of situatedness of intelligence mandates effective agent models and technologies enabling the engineering of agent-based systems immersed within dynamic and articulated pervasive computing environments. Moving MAS coordination toward situatedness - from both a theoretical and a technological viewpoint-is then a fundamental step toward intelligent MAS in pervasive computing scenarios. In this paper we show how a language for MAS coordination - ReSpecT - can be extended according to a meta-model which provides a simple and solid grounding for MAS situatedness - A&A (Agents & Artifacts) - and present a simple case study where the extended A&A ReSpecT is used to coordinate an agent-oriented pervasive system for sensing and controlling environmental properties.","PeriodicalId":259447,"journal":{"name":"2008 IEEE 17th Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126451835","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}
