Call for Papers: PPHPS 2012 Conference
by LRZ aktuell June 22, 2012

Analysis of Performance and Power for Highly Parallel Systems Special issue of Concurrency and Computation: Practice and Experience (CCPE) ----------------------------------------------------------------------- This special issue will be focused on how performance and power properties of modern highly parallel systems can be analyzed using state-of-the-art modeling and analysis techniques, and real-world applications and tools. Complex, hierarchical architectures are now the standard for almost all highly parallel computer systems. Without a good grip on relevant performance limitations any optimization attempt is just a shot in the dark. Hence, it is vital to fully understand the performance properties and bottlenecks that come about with clustered multi- & many-core, multi-socket nodes. Another crucial aspect of modern systems is the complex interplay between power constraints and the need for compute performance. The challenges ahead are many-fold as systems scale in size. While parallelism is increasing, memory systems, interconnection networks, storage, and uncertainties in programming models all add to the complexities. More rapid realization of energy savings will require significant increases in measurement resolution and optimization techniques. The interplay between performance, power, and reliability also leads to complex trade-offs. Of particular interest are papers that identify and analyze novel ideas rather than providing incremental advances in the following areas: * Performance modeling techniques at core, socket, node, and system levels * State-of-the-art tools for analyzing performance and power * Novel techniques that enable power and/or energy optimizations * Experiences from current large-scale systems and applications * Analysis of future technologies that will provide improved energy efficiency ----------------------------------------------------------------------- Submission Guidelines Work that is submitted to this special issue must not have been previously published or currently being considered by other journal or conference venues. However, the papers that have been previously published with reputed conferences can be considered for publication in the special issue if they are substantially revised with at least 30% new content. Every submitted paper will receive at least three reviews. There is a 20 page max length limit (12 point single space, inclusive of figures and tables). Wiley has LaTeX templates that can be used by authors. Either LaTeX or Word submissions will be accepted. Submissions should be made through Manuscript Central (http://mc.manuscriptcentral.com/ cpe) and must refer to "PPHPS 2012 special issue" in step 4 of the submission process. The CCPE submission guidelines can be found at http://www.cc-pe.net/journalinfo/authors.html Please also note the additional instructions for submission to CCPE special issues at http://www.cc-pe.net/journalinfo/issues/authorinstructions.html ----------------------------------------------------------------------- Important Dates Submission deadline: July 30th 2012 Notification of acceptance: September 16th 2012 Final Papers due: November 11th 2012 Final Decisions: December 14th 2012 ----------------------------------------------------------------------- Special Issue Guest Editors Georg Hager University of Erlangen, Germany Darren J.

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.
