The new benchmark tool, named N-SPEK (Networked-Storage Performability Evaluation Kernel module), consists of a controller, several workers, one or more probers, and several fault injection modules. N-SPEK is highly accurate and efficient since it runs at kernel level and eliminates skews and overheads caused by file systems. It allows a SAN architect to generate configurable storage workloads to the SAN under test and to inject different faults into various SAN components such as network devices, storage devices, and controllers. Available performances under different workloads and failure conditions are dynamically collected and recorded in the N-SPEK over a spectrum of time. To demonstrate its functionality, we apply N-SPEK to evaluate the performability of a specific iSCSI-based SAN under Linux environment. Our experiments show that N-SPEK not only efficiently generates quantitative performability results but also reveals a few optimization opportunities for future iSCSI implementations.","PeriodicalId":433323,"journal":{"name":"CCGrid 2003. 3rd IEEE/ACM International Symposium on Cluster Computing and the Grid, 2003.

The result is called the Open Grid Services Architecture (OGSA). This paper describes a component framework for distributed Grid applications that is consistent with that model. The framework, called XCAT, is based on the U.S. Department of Energy Common Component Architecture (CCA) but with an implementation based on the standard Web Services stack. Using this framework, an application programmer can compose an application from a set of distributed components. The result is a set of Web Services that collectively represent the executing application instance. This paper describes the basic architecture of XCAT and the design issues to be considered for a component to serve as both a CCA and Open Grid Service Infrastructure (OGSI) service.","PeriodicalId":433323,"journal":{"name":"CCGrid 2003. 3rd IEEE/ACM International Symposium on Cluster Computing and the Grid, 2003.

This paper presents a lightweight Grid solution for the deployment of multi-parameters applications on a set of clusters protected by firewalls. The system uses a hierarchical design based on Condor for managing each cluster locally and XtremWeb for enabling resource sharing among the clusters. We discuss the security and fault tolerance mechanisms used for this design and demonstrate the usefulness of the approach measuring the performances of a multi-parameters bio-chemistry application deployed on two sites: University of Wisconsin/Madison and Paris South University. This experiment shows that we can efficiently and safely harness the computational power of about 200 PC distributed on two geographic sites.","PeriodicalId":433323,"journal":{"name":"CCGrid 2003. 3rd IEEE/ACM International Symposium on Cluster Computing and the Grid, 2003.

Amongst others, the maturing grid technology aims to address them. To take full advantage of the grid capabilities and enhance its effectiveness in complex and dynamic computational environments, we must make service management more stable, less computationally expensive and more autonomic. In this paper, we propose a synthetic approach to deal with service management in large Unix datacentres that involves the employment of intelligent agents and ontologies. These agents can automatically detect and correct faults at run-lime and manage services.","PeriodicalId":433323,"journal":{"name":"CCGrid 2003. 3rd IEEE/ACM International Symposium on Cluster Computing and the Grid, 2003.

These factors are the separate policies for suspension and migration of executing applications employed by these migration frameworks, the use of pre-defined conditions for suspension and migration and the lack of knowledge of the remaining execution time of the applications. In this paper we describe a migration framework for performance oriented Grid systems that implements tightly coupled policies for both suspension and migration of executing applications and takes into account both system load and application characteristics. The main goal of our migration framework is to improve the response times for individual applications. We also present some results that demonstrate the usefulness of our migration framework.","PeriodicalId":433323,"journal":{"name":"CCGrid 2003. 3rd IEEE/ACM International Symposium on Cluster Computing and the Grid, 2003.

Many self-describing scientific data file formats have also emerged, which have structural metadata to help navigate the multi-dimensional arrays that are stored in the files. The files may also contain application-specific semantic metadata. In this paper, we discuss efficient methods for performing searches for subsets of multi-dimensional data objects, using semantic information to build multidimensional indexes, and group data items into properly sized chunks to maximize disk I/O bandwidth. This work is the first step in the design and implementation of a generic indexing library that will work with various high-dimension scientific data file formats containing semantic information about the stored data. To validate the approach, we have implemented indexing structures for NASA remote sensing data stored in the HDF format with a specific schema (HDF-EOS), and show the performance improvements that are gained from indexing the datasets, compared to using the existing HDF library for accessing the data.","PeriodicalId":433323,"journal":{"name":"CCGrid 2003. 3rd IEEE/ACM International Symposium on Cluster Computing and the Grid, 2003.

CARD drivers have been implemented as Linux kernel modules which can flexibly accommodate various cooperative caching algorithms. We designed and implemented a decentralized policy called Home-based Serverless Cooperative Caching (HSCC).
