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......

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......

GridMapper: a tool for visualizing the behavior of large-scale distributed systems
- Trang 179-187
Grid applications can combine the use of computation, storage, network, and other resources. These resources are often geographically distributed, adding to application complexity and thus the difficulty of understanding application performance. We present GridMapper, a tool for monitoring and visualizing the behavior of such distributed systems. GridMapper builds on basic mechanisms for registeri......

Evaluating Web services based implementations of GridRPC
- Trang 237-245
GridRPC is a class of Grid middleware for scientific computing. Interoperability has been an important issue, because current GridRPC systems each employ its own protocol. Web services, where XML-based standards such as SOAP and WSDL are expected to see widespread use, could be the medium of interoperability; however it is not clear if 1) XML-based schemas have sufficient expressive power for Grid......

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......

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
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 các......

Using kernel couplings to predict parallel application performance
- 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......

Distributed computing with load-managed active storage
- Trang 13-23
One approach to high-performance processing of massive data sets is to incorporate computation into storage systems. Previous work has shown that this active storage model is effective for a variety of problems. This paper explores opportunities to use active storage as a basis for exploiting asymmetric parallelism in applications using a streaming computation model on collections of fixed-size re......

An enterprise-based grid resource management system
- Trang 83-90
As the Internet began its exponential growth into a global information environment, software was often unreliable, slow and had difficulty in interoperating with other systems. Supercomputing node counts also continue to follow high growth trends. Supercomputer and grid resource management software must mature into a reliable computational platform in much the same way that web services matured fo......
