Using kernel couplings to predict parallel application performance
Proceedings 11th IEEE International Symposium on High Performance Distributed Computing - - Trang 125-134
Performance models provide significant insight into the performance relationships between an application and the system used for execution. The major obstacle to developing performance models is the lack of knowledge about the performance relationships between the different functions that compose an application. This paper addresses the issue by using a coupling parameter, which quantifies the int...... hiện toàn bộ

A case for proactivity in directory services
Proceedings 11th IEEE International Symposium on High Performance Distributed Computing - - 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...... hiện toàn bộ

Design and evaluation of a resource selection framework for Grid applications
Proceedings 11th IEEE International Symposium on High Performance Distributed Computing - - Trang 63-72
While distributed, heterogeneous collections of computers ("Grids") can in principle be used as a computing platform, in practice the problems of first discovering and then organizing resources to meet application requirements are difficult. We present a general-purpose resource selection framework that addresses these problems by defining a resource selection service for locating Grid resources t...... hiện toàn bộ

Thiết kế và triển khai các dịch vụ thông tin an toàn cho lưới ASCI Dịch bởi AI
Proceedings 11th IEEE International Symposium on High Performance Distributed Computing - - Trang 209-214
Dịch vụ thông tin là một phần không thể tách rời trong kiến trúc lưới. Đây là nền tảng để xác định các tài nguyên và trạng thái của chúng. Quan trọng hơn, người dùng của lưới có thể hình dung về cách thức hoạt động của lưới, hiệu suất của nó và những khả năng mà nó có thông qua các dịch vụ thông tin. Sáng kiến Tính toán Chiến lược Tăng tốc (ASCI) đã thiết kế và triển khai một bộ dịch vụ lưới trong...... hiện toàn bộ

Architecture requirements for commercializing Grid resources
Proceedings 11th IEEE International Symposium on High Performance Distributed Computing - - Trang 215-224
Contemporary computing systems, especially large-scale systems such as Grids promise ultra-fast ubiquitous utility computing, always available at the flip of a switch. A major unresolved issue is the organization and efficient usage of such infrastructure in a commercial context where several entities compete for shared resources. This has long been resolved for conventional utility resources such...... hiện toàn bộ

Adaptive timeout discovery using the Network Weather Service
Proceedings 11th IEEE International Symposium on High Performance Distributed Computing - - 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...... hiện toàn bộ

A peer-to-peer approach to resource location in grid environments
Proceedings 11th IEEE International Symposium on High Performance Distributed Computing - - 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...... hiện toàn bộ

Scalability of a distributed neural information retrieval system
Proceedings 11th IEEE International Symposium on High Performance Distributed Computing - - Trang 423
Summary form only given. AURA (Advanced Uncertain Reasoning Architecture) is a generic family of techniques and implementations intended for high-speed approximate search and match operations on large unstructured datasets. AURA technology is fast, economical, and offers unique advantages for finding near-matches not available with other methods. AURA is based upon a high-performance binary neural...... hiện toàn bộ

Coven-a framework for high performance problem solving environments
Proceedings 11th IEEE International Symposium on High Performance Distributed Computing - - Trang 291-298
Presents the design of the Coven framework for construction of problem solving environments (PSEs) for parallel computers. PSEs are an integral part of modern high performance computing (HPC) and Coven attempts to simplify PSE construction. Coven targets Beowulf cluster parallel computers but independent of any particular domain for the PSE. Multithreaded parallel applications are created with Cov...... hiện toàn bộ

A metascheduler for the Grid
Proceedings 11th IEEE International Symposium on High Performance Distributed Computing - - Trang 343-351
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
