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...... hiện toàn bộ

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...... hiện toàn bộ

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...... hiện toàn bộ

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...... hiện toàn bộ

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...... hiện toàn bộ

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...... hiện toàn bộ

A high-performance cluster storage server
- Trang 311-320
An essential building block for any data grid infrastructure is the storage server. In this paper we describe a high-performance cluster storage server built around the SDSC Storage Resource Broker (SRB) and commodity workstations. A number of performance critical design issues and our solutions to them are described. We incorporate pipeline optimizations into SRB to enable the full overlapping of...... hiện toàn bộ

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 ...... hiện toàn bộ

Design and evaluation of a resource selection framework for Grid applications
- Trang 63-72
While distributed, heterogeneous collections of computers ("Grids") can in principle be used as a computing platform, in practice the problems of first discovering and then organizing resources to meet application requirements are difficult. We present a general-purpose resource selection framework that addresses these problems by defining a resource selection service for locating Grid resources t...... hiện toàn bộ

Architecture requirements for commercializing Grid resources
- Trang 215-224
Contemporary computing systems, especially large-scale systems such as Grids promise ultra-fast ubiquitous utility computing, always available at the flip of a switch. A major unresolved issue is the organization and efficient usage of such infrastructure in a commercial context where several entities compete for shared resources. This has long been resolved for conventional utility resources such...... hiện toàn bộ
