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......

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......

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 ......

Predicting sporadic grid data transfers
- Trang 188-196
The increasingly common practice of replicating datasets and using resources as distributed data stores in grid environments has led to the problem of determining which replica can be accessed most efficiently. Due diverse performance characteristics and load variations of several components in the end-to-end path linking these various locations, selecting a replica from among many requires accura......

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 ......

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......

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......
