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......

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......

Distributed model coupling framework
- Trang 284-290
An implementation of a distributed model coupling framework is documented. This framework provides the infrastructure for a data-flow approach for solving the problem of distributed numerical models sharing coupling information. There exists a centralized server which stores coupling information such as surface fluxes. This information is then passed to client applications (numerical models) throu......

The performance of processor co-allocation in multicluster systems
- Trang 414
In systems consisting of multiple clusters of processors interconnected by relatively slow communication links, co-allocation may be required. We study its performance by means of simulations, depending on the structure and sizes of jobs, and the communication speed ratio. We model a multicluster with C clusters of identical processors. The workload consists of rigid jobs that require fixed number......

Location-transparent naming in grid computing using Legion-G
- Trang 418
Globus is a powerful toolkit but lacks location transparency in its naming system, due to a reliance on URLs. In practical terms, this means that a Grid user (or software running on behalf of the user) must know precisely where Grid entities are. The problem is that hardware reconfiguration, file system reorganization, and changes in organizational structure can often result in dangling links. At ......

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......

Grid-based knowledge discovery services for high throughput informatics
- Trang 416
Discovery Net is an application layer for providing grid-based knowledge discovery services. These services allow scientists to create and manage complex knowledge discovery workflows that integrate data and analysis routines provided as remote services. They also allow scientists to store, share and execute these workflows as well as publish them as new services. Discovery Net provides a higher l......

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......

UNICORE-Globus interoperability: getting the best of both worlds
- Trang 422
Summary form only given. This work describes a software prototype developed at Research Center Julich to demonstrate the interoperability between UNICORE (Uniform Interface to Computer Resources) and Globus without changes to any of the systems. By combining UNICORE's workflow oriented approach to job submission with Globus, grid users can gain seamless access to a wide number of Globus enabled sy......
