Extending the EGEE grid with XtremWeb-HEP desktop grids
Desktop Grids and Service Grids are widely used by scientific
communities to execute high throughput application. The
European EDGeS project aims at developing the technologies to
bridge these two kinds of Grid technologies together.
In this paper, we present the development and the application
of these new technology to extend the EGEE Grid with XtremWeb-
HEP based Desktop Grids. We present the setup of the distributed
infrastructure which enables EGEE users’ jobs to run on one
of the three various XtremWeb-HEP DGs. We describe the new
volunteer computing project EGEE@Home based on XtremWeb-
HEP middleware. To evaluate the capacity of our technology, we
present a performance measurement of the main components and
conclude that the overhead is kept reasonable despite the fact that
the infrastructure is highly distributed
Monitoring the EDGeS project infrastructure
EDGeS is an European funded Framework Program 7 project that aims to connect desktop and service grids together. While in a desktop grid, personal computers pull jobs when they are idle, in service grids there is a scheduler that pushes jobs to available resources. The work in EDGeS goes well beyond conceptual solutions to bridge these grids together: it reaches as far as actual implementation, standardization, deployment, application porting and training. One of the work packages of this project concerns monitoring the overall EDGeS infrastructure. Currently, this infrastructure includes two types of desktop grids, BOINC and XtremWeb, the EGEE service grid, and a couple of bridges to connect them. In this paper, we describe the monitoring effort in EDGeS: our technical approaches, the goals we achieved, and the plans for future work
EDGeS: bridging EGEE to BOINC and XtremWeb
Desktop Grids, such as XtremWeb and BOINC, and Service Grids, such as EGEE, are two different approaches for science communities to gather computing power from a large number of computing resources. Nevertheless, little work has been done to combine these two Grid technologies in order to establish a seamless and vast Grid resource pool. In this paper we present the EGEE Service Grid, the BOINC and XtremWeb Desktop Grids. Then, we present the EDGeS solution to bridge the EGEE Service Grid with the BOINC and XtremWeb Desktop Grids
