Adaptive timeout discovery using the Network Weather Service
- Trang 35-41
In this paper we present a novel methodology for improving the performance and dependability of application-level messaging in Grid systems. Based on the Network Weather Service, our system uses nonparametric statistical forecasts of request-response times to automatically determine message timeouts. By choosing a timeout based on predicted network performance, the methodology improves application......

IQ-RUDP: coordinating application adaptation with network transport
- Trang 369-378
Our research addresses the efficient transfer of large data across wide-area networks, focusing on applications like remote visualization and real-time collaboration. To attain high performance in the real-time exchange of data across collaborating machines and end users, we are developing and evaluating methods and techniques for coordinating application-level with network transport-level adaptat......

Software architecture-based adaptation for Grid computing
- Trang 389-398
Grid applications must increasingly self-adapt dynamically to changing environments. In most cases, adaptation has been implemented in an ad hoc fashion, on a per-application basis. This paper describes work which generalizes adaptation so that it can be used across applications by providing an adaptation framework. This framework uses a software architectural model of the system to analyze whethe......

An evaluation of object-based data transfers on high performance networks
- Trang 255-264
We describe FOBS: a simple user-level communication protocol designed to take advantage of the available bandwidth in a high-bandwidth, high-delay network environment. We compare the performance of FOBS with that of TCP both with and without the so-called Large Window extensions designed to improve the performance of TCP in this type of network environment. It is shown that FOBS can obtain on the ......

Location-transparent naming in grid computing using Legion-G
- Trang 418
Globus is a powerful toolkit but lacks location transparency in its naming system, due to a reliance on URLs. In practical terms, this means that a Grid user (or software running on behalf of the user) must know precisely where Grid entities are. The problem is that hardware reconfiguration, file system reorganization, and changes in organizational structure can often result in dangling links. At ......

GriPhyN and LIGO, building a virtual data Grid for gravitational wave scientists
- Trang 225-234
Many Physics experiments today generate large volumes of data. That data is then processed in a variety of ways in order to achieve the understanding of fundamental physical phenomena. The goal of the NSF-funded GriPhyN project (Grid Physics Network) is to enable scientists to seamlessly access data whether it is raw experimental data or a data product which is a result of further processing. GriP......

Local discovery of system architecture - application parameter sensitivity: an empirical technique for adaptive grid applications
- Trang 399-407
This study presents a technique that can significantly improve the performance of a distributed application by allowing the application to locally adapt to architectural characteristics of distinct resources in a distributed system. Application performance is sensitive to system architecture-application parameter pairings. In a distributed or Grid enabled application, a single parameter configurat......

Adaptive online data compression
- Trang 379-388 - 2002
Quickly transmitting large datasets in the context of distributed computing on wide area networks can be achieved by compressing data before transmission, However such an approach is not efficient when dealing with higher speed networks. Indeed, the time to compress a large file and to send it is greater than the time to send the uncompressed file. In this paper we explore and enhance an algorithm......

A case for proactivity in directory services
- Trang 415
In this paper, we argue that an exclusively inactive interface to directory services can hinder server scalability and indirectly restrict the behavior of potential applications. We propose to extend directory services' interfaces with a proactive mode by which clients can express their interest in (and be notified of) changes in the environment. These notification channels can be subsequently cus......

A peer-to-peer approach to resource location in grid environments
- Trang 419
Computational grids provide mechanisms for sharing and accessing large and heterogeneous collections of remote resources such as computers, online instruments, storage space, data, and applications. Resources are requested by specifying a set of desired attributes. Resource attributes have various degrees of dynamism, from mostly static attributes, such as operating system version, to highly dynam......
