An algorithm for parallel processing the discrete nonlinear system for solving Fredholm integro-differential equations with twopoint boundary conditions on a PC cluster is considered. The cost of calculating the history terms is expensive and ...

This paper describes the program execution framework being developed by the Grid Application Development Software (GrADS) Project. The goal of this framework is to provide good resource allocation for Grid applications and to support adaptive ...

In this paper, we consider the problem of allocating a large number of independent, equal-sized tasks to a heterogeneous "grid" computing platform. We use a tree to model a grid, where resources can have different speeds of computation and communication,...

This paper describes a scalable and reliable multicast communication service for developing distributed applications in Java. The service is based on MPDT, a dual-token logical ring-based multicast protocol proposed by us. MPDT ensures total ordering of ...

In this paper we present a game theoretic framework for obtaining a user-optimal load balancing scheme in heterogeneous distributed systems. We formulate the static load balancing problem in heterogeneous distributed systems as a noncooperative game ...

As the platform for wide-area distributed applications, the middleware architecture should support adaptability, scalability, mobility, reliability and security. However, current middleware solutions cannot meet these requirements. The middleware ...

In this paper we present the design and implementation of a Pluggable Fault Tolerant CORBA Infrastructure that provides fault tolerance for CORBA applications by utilizing the pluggable protocols framework that is available for most CORBA ORBs. Our ...

Next generation distributed object systems will be required to support millions if not billions of objects and to persist for long periods of time, such as a simulation of the entire World Web Web or modeling of protein folding. If these complex object ...

The focus of this study is how we can efficiently implement a novel neural network algorithm on distributed systems for concurrent execution. We assume a distributed system with heterogeneous computers and that the neural network is replicated on each ...

An important aspect of location-aware services is the management of location information. To this end, location information needs to be transferred from a mobile device, which determines this information by means of a local positioning sensor (such as ...

Wireless sensor networks with thousands of tiny sensor nodes, are expected to find wide applicability and increasing deployment in coming years, as they enable reliable monitoring and analysis of the environment. In this paper, we propose a hybrid ...

We describe the design and the implementation of the CFS (Cluster File System) storage system which is dedicated to video streams. Our goal is to provide a system with the following features: 1) High number of supported streams at a low cost. 2) ...

Real-time intensive signal processing applications have been traditionally deployed on various custom platforms. Meanwhile, the enterprise computing market had spurred the advent of inexpensive and powerful systems based on widely available processors. ...

This paper proposes a new technique called CORBAas-needed to improve the performance of distributed CORBA applications. CORBA-as-needed allows distributed CORBA applications to first detect if the interoperability functionality of CORBA communication ...

This paper studies cluster load balancing policies and system support for fine-grain network services. Load balancing on a cluster of machines has been studied extensively in the literature, mainly focusing on coarse-grain distributed computation. Fine-...

During the last few years, the concepts of cluster computing and heterogeneous networked systems have received increasing interest. The popularity of using Java for developing parallel and distributed applications that run on heterogeneous distributed ...

Peer-to-peer storage architecture aims to aggregating the storage of individual computers (peers) to form a universal shared storage space, in which all peers undertake identical roles. The fully distributed nature of such architecture makes it possible ...

In this paper we are concerned with the efficient use of a collection of disk-based storage systems and computing platforms in a heterogeneous setting for retrieving and processing large scientific datasets. We demonstrate, in the context of a data-...

Cluster architecture is a cost-effective approach to building up scalable servers. For I/O-intensive videoon-demand (VoD) applications, network bandwidth is usually the primary bottleneck. In this paper, we propose a request redirection strategy to ...

Future scalable, high throughput, and high performance applications are likely to execute on platforms constructed by clustering multiple autonomous distributed servers, with resource access governed by agreements between the owners and users of these ...
