Brief Bio
Peter started his career in 1973, when he joined the World's famous Research Center, Bell Laboratories (Bell Labs has produced over the years 6 Nobel Laureates), and worked until 1979. He then joined Oakland University in Rochester Michigan as an associate Professor of Engineering. He worked at Oakland University until 1981 when he joined ATT International and subsequently NYNEX International until 1995. From 1990 to present he has been at Technical University of Crete. While at Oakland University, he first proposed and then worked on and completed the feasibility study for the development of a Technology Park on the University campus, which finally led to the establishment of a major Technology Park at the University. His work at Bell Labs resulted in the publication of an IEEE reprint book on Interference Analysis of Communication Systems and a number of technical paper on interference analysis of satellite orbit interspacing where finally his work led to the change of the satellite orbit interspacing by ITU. He is also the Author/Editor of twelve other Books in the general Area of Telecommunication Systems. He has presented many Tutorials in International Conferences on security applications in Telecommunications. At ATT and NYNEX, he worked as a Technical Director whose responsibility was to lead a team dealing with techno-economic studies on various large National and International Telephone Systems including the design of the security network for the Winter Olympics in France in 1986. Later at the TUC worked for the development of the Technology Park of Chania and has had various administrative duties besides his teaching and research responsibilities. He is the founder of the Telecommunication Systems Research Institute of Crete, a research center for the training of Ph.D. students in Telecommunications, associated with and in close collaboration with various research centers and Universities in Europe and the United States. He is a member of the Editorial Board of the International Journal of Communications, International Journal of Satellite Systems and Networking and has been a reviewer for many Technical International Journals. His latest interests are focused on the application of various heuristic methods on network systems security. He is a founding member of the IEEE technical committee on CIS. Also a founding Editorial Board member for the establishment of CHINA COMMUNICATIONS Technical Journal and served as THE FIRST guest Editor of CHINA COMMUNICATIONS for two special issues CIS. He is also on the Editorial Board of a Leading Turkish Electronics Journal. In 2014, four of his publications on communication and information security were awarded the status of BEST READINGS by IEEE including the unique HANDBOOK ON COMMUNICATION AND INFORMATION SECURITY (CIS). From 23-27 September 2016, he was invited to present in SINGAPORE a three-day course on SURVIVABILITY of CRITICAL WIRELESS NETWORKS to a group of communications professionals.


Abstract
The problem of survivability of wireless network systems has been around for a long time. Due to the fact that as a concept   survivability consists of various components  such as reliability, availability, fault tolerance  and security   and each one of them could be of major importance  and satisfy the requirements  of  a specific survivability problem, as a whole  Survivability did not receive the attention it deserves as far as it concerns   the application of sophisticated  techniques of signal  processing  for  its quantification  . The keynote speech , for the first time, will attempt to deal effectively with the problem of signal processing based  quantification  of survivability by  breaking  the   wireless   network system under consideration   into  a seven layer  model and then investigate  quantitatively which component of survivability  applies to each layer  in order to establish an overall  quantifiable survivable system. Depending on the model used for survivability quantification various appropriate  signal processing techniques  are applied for the determination of a specific survivability metric.



 

 

Speeding up the execution of numerical computations and simulations with rCUDA

Jose Duato

Brief Bio

Jose Duato is Professor in the Department of Computer Engineering (DISCA) at the Technical University of Valencia.
His current research interests include interconnection networks, on-chip networks, and multicore and multiprocessor architectures. He published over 500 refereed papers. According to Google Scholar, his publications received more than 12,000 citations. He proposed a theory of deadlock-free adaptive routing that has been used in the design of the routing algorithms for the Cray T3E supercomputer, the on-chip router of the Alpha 21364 microprocessor, and the IBM BlueGene/L supercomputer. He also developed RECN, a scalable congestion management technique, and a very efficient routing algorithm for fat trees that has been incorporated into Sun Microsystem's 3456-port InfiniBand Magnum switch. Prof. Duato led the Advanced Technology Group in the HyperTransport Consortium, and was the main contributor to the High Node Count HyperTransport Specification 1.0. He also led the development of rCUDA, which enables remote virtualized access to GP-GPU accelerators using a CUDA interface.
Prof. Duato is the first author of the book "Interconnection Networks: An Engineering Approach". He also served as a member of the editorial boards of IEEE Transactions on Parallel and Distributed Systems, IEEE Transactions on Computers, and IEEE Computer Architecture Letters.

Prof. Duato was awarded with the National Research Prize in 2009 and the “Rey Jaime I” Prize in 2006.


Abstract
This keynote will present some techniques to speed up the execution of numerical computations and simulations, with special emphasis on the use of hardware accelerators. The talk will present the architecture of the most popular accelerators currently in use, the implications for the programmers, and the main limitations of the current commercial implementations. The talk will also describe a recent technology for virtualizing accelerators that dramatically improves the utilization and effective computing power of those accelerators while reducing power consumption. Finally, the measured benefits in some real computing installations will be shown.

Abstract
Current emergency systems and 112 services are based on legacy telecommunication technologies, which cannot cope with IP-based services that European citizens use every day. Some of the related limitations are the partial media support (so far, only voice calls and SMS are accepted), the lack of integration of social media, and the use of an analogue modem for providing e-Call services with limited data amount. As most operators, have started migrating towards broadband IP-based infrastructures, current emergency systems need also to be upgraded/adapted to fulfil regulatory requirements in terms of Next Generation emergency services. Τhe main objective of the talk is the design and implementation of a Next Generation platform capable of accommodating rich-media emergency calls that combine voice, text, and video, thus constituting a powerful tool for coordinating communication among citizens, call centres and first responders. Additionally, issues such as call routing/redirection to the closest available call centre, retrieval of the caller location, hoax calls prevention, support for people with disabilities, and integration of social media will be addressed. The talk will address solutions that enable users to make emergency calls across heterogeneous devices (e.g. PCs, TV sets, mobile, AAC and haptic devices) using various mature technologies, including those making use of the Session Initiation Protocol (SIP), the IP Multimedia Subsystem (IMS), and WebRTC framework. Suitable use cases will also showcase how the e-Call concept can benefit from the IP technologies by allowing audio-video calls towards the emergency call centres and complementing location information, with photos and videos.
