Wissenheim

Wissenheim is a distributed interactive 3D virtual world for edutainment and entertainment. The game is started by each participant by using the XtreemOS xconsole. The application loads the persistent game state information by using the XtreemOS grid file system (XtreemFS.) Subsequently, the scene graph is transparently distributed and replicated by the XtreemOS Object Sharing Service (OSS). Avatar interactions and scene graph changes are synchronized through speculative transactions provided by the OSS. In case of severe errors the application relies on the grid checkpointing service (XtreemGCP).

XtreemOS-MD Grid Media Player

GPlayer is an application developed by Telefónica for smartphones within the XtreemOS-MD context. This mobile application is a mediaplayer that uses the GRID capabilities provided by XtreemOS to transcode any video to a more suitable format and/or size.

Sharing a smartphone's 3G connection

Xtreemos-MD provides the capability to share input-output resources of a smartphone, e.g. 3G access or GPS device, within the GRID. We show how a N900 shares its 3G connection, using a p2p secure connection, with a user authorized in the XtreemOS GRID.

XtreemOS-MD On-Demand File Sharing demo

Xtreemos-MD provides to mobile devices (like smartphones and PDAs) the capability of sharing the files stored locally, which will be uploaded to the Grid file system (XtreemFS) just when requested by another user authorized in the XtreemOS Grid. This feature is what we call “on-demand file sharing”.

In this demo you can see how a Nokia N800 user configures the resource sharing to share the pictures’ folder and takes a new picture with the terminal, while another user with a Nokia N900 access to the shared folder to retrieve that photo file. While the data shared is being accessed and uploaded to the XtreemFS, the resource monitoring tool will show it with a different icon in the status bar.
