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......

Bringing the grid to the biomedical workbench
- Trang 417
Modem biological research is data intensive and relies on an efficient informatics infrastructure. Research on the genetic control of embryo development involves large volume image data requiring significant computing resources for reconstruction, mapping and analysis. This poster describes a demonstrator for delivering secure and transparent access to high-performance computing to the laboratory ......

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......

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......

A decentralized, adaptive replica location mechanism
- Trang 24-32
We describe a decentralized, adaptive mechanism for replica location in wide-area distributed systems. Unlike traditional, hierarchical (e.g, DNS) and more recent (e.g., CAN, Chord, Gnutella) distributed search and indexing schemes, nodes in our location mechanism do not route queries, instead, they organize into an overlay network and distribute location information. We contend that this approach......

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......

A batch script generator Web service for computational portals
- Trang 421
Computational portal developers often reimplement functionality found in existing portals because there are no common discovery and access mechanisms in place to enable sharing of portal functions. The Web services architecture provides an implementation independent, protocol based mechanism for entities to find, share, and invoke remote services. We developed complementary web services at SDSC an......

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 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......
