----------------------------------------------------------------------- CALL FOR PAPERS 7th International Conference on Partitioned Global Address Space Programming Models (PGAS 2013) Edinburgh, Scotland, UK October 3-4, 2013 http://www.pgas2013.org.uk ----------------------------------------------------------------------- Partitioned Global Address Space (PGAS) programming models offer a shared address space model that simplifies programming while exposing data/thread locality to enhance performance. The PGAS conference is the premier forum to present and discuss ideas and research developments in the area of: PGAS models, languages, compilers, runtimes, applications and tools, PGAS architectures and hardware features. TOPICS Submissions are invited in related areas, including, but not limited to: * Applications. New applications that are uniquely enabled by the PGAS model, existing applications and effective application development practices for PGAS codes. * Performance Analysis of application performance over various programming models. * Developments in Programming Models and Languages. PGAS models, language extensions, and hybrid models to address emerging architectures, such as multicore, hybrid, heterogeneous, SIMD and reconfigurable architectures. * Tools, Compilers, and Implementations. Integrated Development Environments, performance analysis tools and debuggers. Compiler optimisations for PGAS languages, low level libraries, memory consistency models. Hardware support for PGAS languages, performance studies and insights, productivity studies, and language interoperability. SUBMISSION CATEGORIES and GUIDELINES Papers should report on original research, and should include enough background material to make them accessible to the entire PGAS research community. Papers describing experiences should indicate how they illustrate general principles; papers about parallel programming foundations should indicate how they relate to practice. There are three submission categories: * Research papers: submission of full paper of up to 8 pages at 10pt font. * "Hot" PGAS papers: submission of extended abstracts, 3 pages maximum at 10pt font. Submissions in this category target work-in-progress research and will, if accepted, be given shorter presentation slots than the full research papers. * Posters: submission of extended abstracts, 1 page maximum at 10pt font.

Character Generator Protocol aus dem Internet ins MWN wird gesperrt
by LRZ aktuell June 11, 2013

June 11, 2013

In letzter Zeit werden vermehrt Systeme im Muenchner Wissenschaftsnetz fuer Denial of Service (DoS und DDos) Angriffe mit dem Character Generator Protokoll (chargen, UDP Port 19) missbraucht. Der Dienst wird nur zum Testen und zur Fehlersuche benoetigt. Das LRZ hat sich deshalb entschlossen, diesen Verkehr aus dem Internet ins MWN zu sperren. Die Sperre wird am Mittwoch, den 12.06.2013 um 09:00 Uhr aktiviert. Bei einer benoetigten und begruendeten Nutzung des chargen-Protokolls auch von ausserhalb des MWN koennen bestimmte Adressen von diesen Sperren ausgenommen werden. Sollten Sie Bedarf nach solchen Ausnahmen haben, geben Sie bitte die freizuschaltenden externen IP-Adressen ueber das Service-Desk des LRZ bekannt.

June 6, 2013

Changes to this message: Update Unfortunately, there was a typing error in the date of the lecture. It will be on * Friday, June 7th, 2013 * 11 h c.t. * LRZ lecture hall Abstract: CIMA Research Foundation is a private non-profit research organization. It s committed to promote the scientific research, technological development and higher education in engineering and environmental sciences in order to improve civil protection, public health and preservation of aquatic and terrestrial ecosystems. CIMA's founding Institutions are the National Civil Protection Department of Italy, the University of Genoa, and local Authorities. The mission Foundation has got from the founders is to observe the Earth relevant processes, to predict the scenarios generated by them, using science in the service of the protection of citizens and of the environment. The speech will address first the research needs and the innovative tools of a modern Civil Protection Agency, in the field of meteorological and hydrological hazards, in order to efficiently predict dangerous events. The implications of the climate change on predicting climatic extremes will be discussed: exchanging the space dimension with the time dimension in observing and modeling is the main reason of the DRIHM project and of the EXPRESS-HYDRO project. The advanced modeling of the weather impacts, as well as the brain observation and its dynamic modeling, are the two modern science fields in which field experts are more in need of the support from ICT research. Biography: Prof. Franco Siccardi is current President of CIMA Research Foundation * Past Professor of Civil Engineering at the University of Genoa Expert in methods for reducing the effects of natural hazards - especially flooding - through weather forecasting, observing networks and satellite sensors. * Sergey Soloviev Medal of the European Geophysical Society of the year 2000 for the outstanding scientific contributions in the area of understanding and mitigation of natural hazards impact. From 1995 to 2001 and from 2006 to present appointed by the Office of the Prime Minister of Italy as member of the National Committee for Extreme Risks. * Presently coordinator of hydrometeo risk section of the committee. Since 1986 to 2005 leader of the research area on Strategies for the Mitigation of Natural Hazards Effects of the Italian Research Group for the Prevention of Hydrogeological Hazards. * From 2004 to 2011 principal investigator of the Opera Project, the Italian Space Agency research and demonstration program for the use of EO data in risk assessment and flood predictions. Since 2011 member of the OCSE expert group on the Global Risk Modeling initiative. Up to 2007 Chairman of Business Consortium COS (OT) Technology for the Earth Observation from Space.
