As both the number of applications grow and grids scale, efficient utilization of the available but shared heterogeneous resources will be essential. The EasyGrid middleware is a hierarchically distributed Application Management System embedded into MPI applications to facilitate their efficient execution in computational grids. The overhead of employing a distinct AMS to make each application system aware does however bring at least two benefits. First, the (scheduling) policies adopted can be tailored to the specific needs of each application leading to improved performance. Second, distributing the management effort amongst the applications themselves makes grid management more scalable. This paper describes a low intrusion implementation of a hybrid scheduling strategy designed to cope with the dynamic behaviour of grid environments. Using application-specific scheduling policies, near-optimal runtimes highlight the advantages of self-scheduling when executing one or more system aware applications on a grid.","PeriodicalId":313448,"journal":{"name":"Middleware for Grid Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133746939","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}

Periodic checkpoints might be taken to guarantee application progression, producing even more data. The classical approach is to employ high-throughput checkpoint servers connected to the computational nodes by high speed networks. In the case of Opportunistic Grid Computing, we do not want to be forced to rely on such dedicated hardware. Instead, we want to use the shared Grid nodes to store application data in a distributed fashion.In this work, we evaluate several strategies to store checkpoints on distributed non-dedicated repositories. We consider the tradeoff among computational overhead, storage overhead, and degree of fault-tolerance of these strategies. We compare the use of replication, parity information, and information dispersal (IDA). We used InteGrade, an object-oriented Grid middleware, to implement the storage strategies and perform evaluation experiments.","PeriodicalId":313448,"journal":{"name":"Middleware for Grid Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123539464","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}

Unfortunately, most OS level protection mechanisms can be turned off after an attacker manages to exploit a vulnerability to gain privileged access.This paper proposes SVGrid, a Secure Virtual Grid computing environment, to protect grid computers' filesystem and network from malicious grid applications. SVGrid works by isolating grid applications in one or more grid virtual machines whose filesystem and network service are moved into a dedicated monitor virtual machine. All file and network access requests are then forced to go through the monitor virtual machine, where security policies can be enforced. The resource compartment guarantees that appropriate security policy enforcement cannot be bypassed or disabled, even if a grid virtual machine is compromised. We tested SVGrid against attacks on grid virtual machine using rootkit and internet worm, SVGrid was able to prevent both of them from maliciously accessing filesystem and network. We also evaluated the performance of SVGrid system and only found that performance cost was reasonable considering the security benefits of SVGrid.","PeriodicalId":313448,"journal":{"name":"Middleware for Grid Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115925650","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}

Experiences and conclusions drawn are in the context of Agreement-based job management systems. A key idea of these extensions is the use of functions for the Guarantee Terms of the Agreement rather than constant values or ranges. Functions may contain variables defined in a particular agreement or be drawn from the known set of reference variables, such as wall-clock time, job start time, etc. We show that such an approach can potentially reduce the negotiation overheads associated with job renegotiation and/or reduce the number of failed agreements.","PeriodicalId":313448,"journal":{"name":"Middleware for Grid Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126610622","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 goal is to develop common Grid application components that can be used by portal developers and administrators to build and deploy on open source portal frameworks. This will allow users to authenticate securely to remote resources and provide transparent access via Grid related tools to manage their tasks efficiently. The current portal technology, JSR 168, is described for the development of Java based applications. The work is substantiated by giving an example of building the UK National Grid Service (NGS) portal. NGS Portal itself works as middleware; it \"glues\" different Grid Resources together in a single location.

The standardization of grids based on web services has resulted in the need for scalable web service discovery mechanisms to be deployed in grids Even though UDDI has been the de facto industry standard for web-services discovery, imposed requirements of tight-replication among registries and lack of autonomous control has severely hindered its widespread deployment and usage. With the advent of grid computing the scalability issue of UDDI will become a roadblock that will prevent its deployment in grids. In this paper we present our distributed web-service discovery architecture, called DUDE (Distributed UDDI Deployment Engine). DUDE leverages DHT (Distributed Hash Tables) as a rendezvous mechanism between multiple UDDI registries. DUDE enables consumers to query multiple registries, still at the same time allowing organizations to have autonomous control over their registries.. Based on preliminary prototype on PlanetLab, we believe that DUDE architecture can support effective distribution of UDDI registries thereby making UDDI more robust and also addressing its scaling issues. Furthermore, The DUDE architecture for scalable distribution can be applied beyond UDDI to any Grid Service Discovery mechanism.","PeriodicalId":313448,"journal":{"name":"Middleware for Grid Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114899880","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}

It is context dependent, thus many types of cache exist. As a consequence, when a cache is required, it is usually built from scratch. Such a solution is time (and money) consuming, in particular in data grid context where several caches may be required. This paper proposes ACS (Adaptable Cache Service), a framework which allows building adaptable cache services. It presents a generic cache definition and provides a description of models implemented in the framework. ACS aims at facilitating the development of cache services for any application.

Within SOA solutions, current approaches for advertising service providers and for allowing prospective clients to discover them are mostly based on centralized registries. Envisioning Virtual Organizations in which all participants are both resource providers and consumers, in a peer-to-peer fashion, seems to be an appealing approach.In this paper we propose the Service-oriented Peer-to-Peer Architecture (SP2A), a framework enabling peer-to-peer resource sharing in Grid environments. Resources are not directly exposed but can be accessed through Resource Provision Services, whose semantically enriched interfaces are published in the network. The framework has been implemented as a Java API, which currently supports a number of important technologies such as JXTA (peer-to-peer routing), Web Services (service deployment), and OWL-S (semantic description of services).","PeriodicalId":313448,"journal":{"name":"Middleware for Grid Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125335066","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}

We demonstrate its programmability using FORTRAN, C++, C# and Java, and discuss its performance over LAN and WAN infrastructures. We also demonstrate its applicability by providing a case-study in the field of experimental aerodynamics. We believe this is the first commodity grid toolkit supporting multiple languages, obviating the need for new CoG toolkits to be developed for languages supported under the .NET framework.
