Adaptive timeout discovery using the Network Weather Service - Trang 35-41
M.S. Allen, R. Wolski, J.S. Plank
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

Local discovery of system architecture - application parameter sensitivity: an empirical technique for adaptive grid applications - Trang 399-407
I.R. Corey, J.R. Johnson, J.S. Vetter
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... hiện toàn bộ

InfoGram: a grid service that supports both information queries and job execution - Trang 333-342
G. von Laszewski, J. Gawor, C.J. Pena, I. Foster
The research described in this paper is performed as part of the Globus Project.
It introduces a new grid service called InfoGram that combines the ability of
serving as information service and as a job execution service. Previously, both
services were architected and implemented within the Globus Toolkit as two
different services with different wire protocols. Our service demonstrates a

Mô hình tổng hợp dịch vụ nhận thức chất lượng dịch vụ quy mô mở cho các lưới tính toán ngang hàng Dịch bởi AI - Trang 73-82
Xiaohui Gu, K. Nahrstedt
Các lưới tính toán ngang hàng (P2P) bao gồm các nút ngang hàng giao tiếp trực
tiếp với nhau thông qua các mạng diện rộng và có thể hoạt động như cả máy khách
và máy chủ. Những hệ thống này đã thu hút được nhiều sự chú ý trong nghiên cứu
kể từ khi chúng thúc đẩy chia sẻ tài nguyên và dịch vụ trên quy mô Internet mà
không tốn chi phí quản lý hay hỗ trợ hạ tầng tập trung. Tuy nhiên, việc tổng hợp

Interactive and descriptor-based deployment of object-oriented grid applications - Trang 93-102
F. Baude, D. Caromel, F. Huet, L. Mestre, J. Vayssiere
Increasing complexity of distributed applications and commodity of resources
through grids are making the tasks of deploying those applications harder. There
is a clear need for standard tools allowing versatile deployment and analysis of
distributed applications. We present here a solution for the deployment and
monitoring of applications written using ProActive, an experimental Java-based
librar... hiện toàn bộ

IQ-RUDP: coordinating application adaptation with network transport - Trang 369-378
Qi He, K. Schwan
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... hiện toàn bộ

BioGRID - An European grid for molecular biology - Trang 412
P. Bala, J. Pytlinski, M. Nazaruk
Recent advances in computer technology, especially grid tools makes them good
candidate for development of user interfaces to computing programs and
resources. Computational grids enable sharing a wide variety of geographically
distributed resources and allow selection and aggregation of distributed
resources across multiple organizations for solving large scale computational
and data intensive pr... hiện toàn bộ

Dynamic right-sizing in FTP (drsFTP): Enhancing Grid performance in user-space - Trang 42-49
M.K. Gardner, Wu-chun Feng, M. Fisk
With the advent of computational grids, networking performance over the
wide-area network (WAN) has become a critical component in the grid
infrastructure. Unfortunately, many high-performance grid applications only use
a small fraction of the available bandwidth because operating systems and their
associated protocol stacks are still tuned for yesterdays WAN speeds. As a
result, network gurus und... hiện toàn bộ

A comparison of TCP automatic tuning techniques for distributed computing - Trang 265-272
E. Weigle, Wu-chun Feng
Rather than painful, manual, static, per-connection optimization of TCP buffer
sizes simply to achieve acceptable performance for distributed applications,
many researchers have proposed techniques to perform this tuning automatically.
This paper first discusses the relative merits of the various approaches in
theory, and then provides substantial experimental data concerning two competing

A metascheduler for the Grid - Trang 343-351
S.S. Vadhiyar, J.J. Dongarra
With the advent of Grid computing, scheduling strategies for distributed
heterogeneous systems have either become irrelevant or have to be extended
significantly to support Grid dynamics. In this paper, we describe a
metascheduling architecture for a Grid system that takes into account both the
application and system level considerations. Results are presented to
demonstrate the usefulness of the ... hiện toàn bộ
