    In the current approaches to workflow scheduling, there is no cooperation between the distributed workflow brokers and as a result, the problem of conflicting schedules occur. To overcome this problem, in this paper, we propose a decentralized and cooperative workflow scheduling algorithm. The proposed approach utilizes a peer-to-peer (P2P) coordination space with respect to coordinating the appli... View full abstract»

    The drift towards new challenges in grid computing, including the utility grid paradigm and service level agreements based on quality-of-service guarantees, implies the need for new, robust, multi-criteria scheduling algorithms that can be applied by the user in an intuitive way. Multiple scheduling criteria addressed by the related grid research include execution time, the cost of running a task ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (588 KB) | HTML iconHTML

    In this paper we present a multicost algorithm for the joint time scheduling of the communication and computation resources that will be used by a task. The proposed algorithm selects the computation resource to execute the task, determines the path to route the input data, and finds the starting times for the data transmission and the task execution, performing advance reservations. We initially ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (687 KB) | HTML iconHTML

    This paper examines the job exchange between parallel compute sites in a decentralized grid scenario. Here, the local scheduling system remains untouched and continues normal operation. In order to establish the collaboration and interaction between sites in a grid context, a middleware layer that is responsible for the migration of jobs is supplemented. Independent users are assumed to submit the... View full abstract»

    The flourishing of Peer-to-Peer (P2P) applications has encouraged extensive research on end-to-end anonymity. In particular, interactive services such as VoIP and instant messaging are becoming extremely popular and require low latency. Preserving the anonymity of users in such services is becoming a major challenge. While existing schemes provide anonymity for the communicating parties; they incu... View full abstract»

    In P2P content distribution systems, there are many cases in which the content can be classified into hierarchically organized categories. In this paper, we propose a hybrid overlay network design suitable for such content called Pastry/NSHCC (Pastry for non- strictly hierarchically categorized content). The semantic information of classification hierarchies of the content can be utilized regardle... View full abstract»

    Peer-to-peer overlays envision a single overlay substrate that can be used (possibly simultaneously) by many applications, but current overlays either target fast, few-hop lookups for contacting directly the responsible nodes, or slower multi-hop lookups that can be used by applications that exploit the overlay topology (like multicast or anycast). In this paper we present Pastel, an extension to ... View full abstract»

    In this work we present a Grid implementation of a FPGA optimization tool. The application is based on a Distributed Genetic Algorithm (DGA). It solves the placement and routing problem into the FPGA design cycle. The Grid infrastructure is based both on gLite middleware and GridWay metascheduler. The DGA 's different islands are sent to the Working Nodes (WN), where they evolve as remote jobs. We... View full abstract»

    Distributed time-stamping enables tolerance to distributed denial of service attacks. However, they involve high cost due to the requirement that all time- stamping units (TSUs), whose number could be numerous, must be audited by trusted third parties. We propose a distributed multi-generation time-stamping scheme with predictable expectation time of notary and minimizing the cost of administratio... View full abstract»
