A Self-Configurable Desktop Grid System On-Demand

Abstract

Desktop Grids have been used intensively to deploy applications at low cost. Applications types are classified into high throughput computing and high throughput data management. Desktop Grids such as Condor, BOINC, XtremWeb and OurGrid provide a wide range of high throughput computing systems. On the other hand, several data management systems such as Bitdew, GatorShare, Stork, GridFTP, have been developed to handle a huge amount of data. Users are restricted to exploit Desktop Grid resources with a specific computing system and a specific data management system. To address this limitation, we propose in this work an extension of the BonjourGrid middleware, to support different data management systems by exploiting existing data protocols and middleware. With BonjourGrid, users of the same infrastructure can select, each one, the desired Desktop Grid middleware among the most popular ones to deploy and execute their applications. Now, users can select in addition to the computing system, the desired data manager protocol in a transparent and decentralized manner. Experimentation, using BitDew and Stork, on the Grid'5000 platform, demonstrate that the new release of BonjourGrid provides with performance and at a low overhead.

Toward a data desktop grid computing based on BonjourGrid meta-middleware

“…In figures 3we propose a Remote Cache for data placement activities, in order to reserve the disk space for application and to transfer the required data from the user site to Bonjour-Grid. Once data are placed on the platform, a second cache called Local Cache is automatically launched to publish and to distribute data over workers [22].…”
