Talk 'Reproducing the face to face meeting in Telepresence'
by LRZ aktuell June 19, 2012

June 19, 2012

Prof. David Roberts Professor of Telepresence | Head of Centre for Virtual Environments and Future Media University of Salford Reproducing the face to face meeting in Telepresence Location: Leibniz Supercomputer Centre 85748 Garching, Boltzmannstr. 1 Room H.E.009 Date: June 21st, 2012, 16:00 - 17:30 Abstract A grand challenge shared between computer science and communication technology is reproducing the face-to-face meeting across a distance. At present, we are some way from reproducing many of the semantics of a face-to-face meeting. Furthermore, while we can reproduce some in certain mediums and others in others, we are currently unable to reproduce most in any. For example while some mediums can show us what someone really looks like and others what or who they are really looking at, communicating both together has not yet been achieved to any reasonable quality across a reasonable distance. This talk explains some of the primary challenges, comparing our approaches to telepresent video conferencing, immersive virtual environments, and 3D video based tele-immersion. Biography Professor David Roberts primary research interest is in creative group work encouraged or supported by immersive mediums. Towards this he leads both the development of new technologies and studies of their use. Through a framework of social human communication that includes verbal and non-verbal communication and the role of objects and environment, he studies how people interact around simulated artefacts in environments enriched or joined through technology. Most of his work has focused on telepresence, and his current focus is on combining VR and computer vision to enhance the naturalness of telecollaboration through free view immersive 3D video.

Upd:Storage maintenance impacts all HPC Systems on June 18
by LRZ aktuell June 18, 2012

June 18, 2012

Changes to this message: Returning to user operation Update on status: The NAS maintenance has been successfully concluded; however returning the HPC cluster systems to user operation is a bit delayed: The MPP, Myrinet, ICE and serial cluster segments are available again, but the UV systems are still in maintenance. Also, the visualization systems GVS3 and GVS4 are not yet in operation. For the status of SuperMIG please see the separate notification. ----------------------------------------------------------------------- Dear users of SuperMIG as well as the Cluster systems, in its ongoing effort to increase the storage capacity and performance on its HPC systems (and especially the new Petascale system that is being prepared for user operation), LRZ has taken new NAS systems into operation. Presently, LRZ is transferring the data on all HOME directories to the new system. In order to take the final step in switching over regular operations, an interruption of services on all HPC systems is necessary. Therefore, on June 18 between 8:00 am and 3:00 pm no user operation will be possible on the Linux Cluster as well as the SuperMIG migration system. Since a reboot of all systems is needed, running jobs will be removed and may require a resubmission.
