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......

Multigrain parallelism for eigenvalue computations on networks of clusters
- Trang 143-149
Clusters of workstations have become a cost-effective means of performing scientific computations. However, large network latencies, resource sharing, and heterogeneity found in networks of clusters and Grids can impede the performance of applications not specifically tailored for use in such environments. A typical example is the traditional fine grain implementations of Krylov-like iterative met......

Thiết kế và triển khai các dịch vụ thông tin an toàn cho lưới ASCI Dịch bởi AI
- 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......

Coven-a framework for high performance problem solving environments
- 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......

A metascheduler for the Grid
- 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 ......

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......

BioGRID - An European grid for molecular biology
- Trang 412
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......

Leveraging run time knowledge about event rates to improve memory utilization in wide area data stream filtering
- Trang 171-178
The dQUOB system conceptualization of data streams as database and its SQL interface to data streams is an intuitive way for users to think about their data needs in a large scale application containing hundreds if not thousands of data streams. Experience with dQUOB has shown the need for more aggressive memory management to achieve the scalability we desire. This paper addresses the problem with......

Flexibility, manageability, and performance in a Grid storage appliance
- Trang 3-12
We present NeST a flexible software-only storage appliance designed to meet the storage needs of the Grid. NeST has three key features that make it well-suited for deployment in a Grid environment. First, NeST provides a generic data transfer architecture that supports multiple data transfer protocols (including GridFTP and NFS), and allows for the easy addition of new protocols. Second, NeST is d......
