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......

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......

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......

An evaluation of object-based data transfers on high performance networks
- Trang 255-264
We describe FOBS: a simple user-level communication protocol designed to take advantage of the available bandwidth in a high-bandwidth, high-delay network environment. We compare the performance of FOBS with that of TCP both with and without the so-called Large Window extensions designed to improve the performance of TCP in this type of network environment. It is shown that FOBS can obtain on the ......

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......

Dynamic monitoring of high-performance distributed applications
- Trang 163-170
Developers and users of high-performance distributed systems often observe performance problems such as unexpectedly low throughput or high latency. Determining the source of the performance problems requires detailed end-to-end instrumentation of all components, including the applications, operating systems, hosts, and networks. However, one must be very careful to design the instrumentation to h......

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......

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 ......

Investigating the limits of SOAP performance for scientific computing
- Trang 246-254
The growing synergy between Web Services and Grid-based technologies will potentially enable profound, dynamic interactions between scientific applications dispersed in geographic, institutional, and conceptual space. Such deep interoperability requires the simplicity, robustness, and extensibility for which SOAP was conceived, thus making it a natural lingua franca. Concomitant with these advanta......
