Grid environments, providing distributed infrastructures, computing resources and data storage, usually show a high degree of heterogeneity and change in their metadata. We propose a platform for collaborative management and maintenance of common metadata for grids. As the conceptual foundation of this platform, a meta model is presented which distinguishes structured descriptions and classific...

Grid computing is a term referring to the combination of computer resources from multiple administrative domains to reach a common computational platform. Mobile Computing is a Generic word that introduces using of movable, handheld devices with wireless communication, for processing data. Mobile Computing focused on providing access to data, information, services and communications anywhere an...

Data management is one of the most fundamental aspects in a Data Grid where potentially Tera-or Petabytes are stored in distributed sites. Although there are many solutions to data management, mass storage systems and file system features are among the most dominant ones. This minisymposium will take out a few of these aspects and discuss them in more detail.

Data grid replication is critical for improving the performance of data intensive applications. Most of the used techniques for data replication use Replica Location Services (RLS) to resolve the logical name of files to its physical locations. An example of such service is Giggle, which can be found in the OGSA/Globus architecture. Classical algorithms also need some catalog and optimization s...

The Grid is an emerging infrastructure for providing coordinated and consistent access to distributed, heterogeneous computational and information storage resources amongst autonomous organizations. Data grids are being built across the world as the next generation data handling systems for sharing access to data and storage systems within multiple administrative domains. A data grid provides l...

The increasingly common practice of (1) replicating datasets and (2) using resources as distributed data stores in Grid environments has lead to the problem of determining which replica can be accessed most efficiently. Due to diverse performance characteristics and load variations of several components in the end-to-end path linking these various locations, selecting a replica location from am...
