In this paper, we present the design of a self organising resource discovery protocol (SORD) for e cient resource discovery and job allocation for cluster computing/Grid scenarios. The protocol is fully distributed and is based on the peer to peer architecture and small world topologies. The evaluation of the protocol is done through simulation. The simulation scenario assumes a QoS enabled Gri...

The networks of today support a wealth of resources which can aid the daily tasks of a diverse user base. Resource discovery is a relatively new field that deals with the problems of finding, organising and accessing these resources in a global network. The architecture model proposed by the DSTC’s Architecture Unit provides a way to specify open distributed application systems. A resource disc...

This paper provides a set of criteria to evaluate the usability of trader user interfaces with respect to resource discovery. The criteria were identified because trader user interface developers sometimes make unrealistic assumptions about the information seeking behavior of their users, leading to interfaces that are difficult to use for resource discovery. This paper uses some insights from ...

Grid systems have gained remarkable importance in the last decade since resource requirements of recent applications increased drastically. Resource discovery in grid systems is a fundamental task which provides searching and locating necessary resources for given processes. There are many different approaches in literature for this problem. Grid resource discovery using centralized and hierarc...

Resource location (or discovery) is a fundamental service for resource-sharing environments: given desired resource attributes, the service returns locations of matching resources. Designing such a service for a Grid environment of the scale and volatility of today’s peer-to-peer systems is not trivial. We explore part of the design space through simulations on an emulated Grid. To this end, we...

A fundamental problem in building large scale Grid resource sharing system is the need for efficient and scalable techniques for discovery and provisioning of resources for delivering expected Quality of Service (QoS) to users’ applications. The current approaches to Grid resource sharing based on resource brokers are non-coordinated since these brokers make scheduling related decisions indepen...

Resource Monitoring and Discovery of large computational data Grids is essential to guarantee high performance and reliability. In this paper, we identify the various resource monitoring and discovery issues and challenges that need to be solved in a large adaptive Grid environment. We survey the existing Grid monitoring solutions and discuss the monitoring and discovery framework that we have ...

One of the most urgent problems presented on the web scenario is the difficulty to capture effective useroriented information. Search engines return tons of data which often are so general as well as useless; sometimes the user request is so specific that no matches occur or they are too poor to satisfy the user expectation. Often the same information is recoverable from different web pages and...

Presents a new model for resource discovery in grids and peerto-peer networks designed to utilise efficiently small numbers of messages for query processing and building of the network. Outlines and evaluates the model through a theoretical comparison with other resource discovery systems and a mathematical analysis of the number of messages utilised in contrast with Chord, a distributed hash t...
