Mazin Yousif, PhD CTO, Cloud Computing IBM Canada
Cloud Computing – A Paradigm Changer
Mazin Yousif is the Chief Technology Officer for Cloud Computing in the Global Technology Services in IBM Canada. Before that, he spent 17+ years holding various technical executive positions at Numonyx, Intel and IBM. He also holds adjunct professor positions at 4 universities. Mazin chaired standard bodies, served as General Chair or Program Chair for many conferences and serves in the editorial board of many journals. He is a frequent speaker in academic and industry conferences on various topics related to cloud, autonomic and green computing. He has also published extensively.
Mazin finished his Master’s and Ph.D. degrees from the Pennsylvania State University in 1987 and 1992, respectively.
Cloud Computing is an emerging computing paradigm envisioned to change all IT landscape facets including technology, business, services and human resources. It is a consumer/delivery model that offers IT capabilities as services, billed based on usage. Many such cloud services can be envisioned, but the leading ones are IaaS (Infrastructure-as-a-Service), PaaS (Platform-as-a-Service), and SaaS (Software-as-a-Service). The underlying cloud architecture includes a pool of virtualized compute, storage and networking resources that get aggregated and launched as platforms to run workloads and satisfy their Service-Level Agreement (SLA). Cloud architectures also include provisions to best guarantee service delivery for clients and at the same time optimize the efficiency of resources for providers. Examples include, but not limited to, elasticity through scaling resources up/down to track workload behavior, extensive monitoring, failure mitigation, and energy optimizations. Two key technologies enable clouds, specifically: (i) Virtualization, the foundation of clouds; and (ii) manageability (autonomics), the command and control of clouds. This talk is intended to provide an overview of cloud computing, its enabling technologies and current challenges. It will also look at clouds’ IT/business ramifications as well as required future research.

Azzedine Boukerche, Professor, University of Ottawa, Canada
Wireless Multimedia Sensor and Actuator System: A Necessary Public Security and Safety Testbed for An Urban Emergency Preparedness class of applications
Dr. A. Boukerche, is a Full Professor of Computer Science and held a Canada Research Chair Position at the University of Ottawa. Prior to this, he was Faculty Member at the Dept. of Computer Sciences and Engineering, University of North Texas. He also worked as a Senior Research Scientist at Metron Corp. located in San Diego, California, where he was leading several DoD projects on data distribution management for large-scale distributed and interactive systems. He also worked as a visiting scientist at Caltech/JPL-NASA, where he contributed to a project centered on the specification and verification of the software used to control interplanetary spacecraft operated by JPL/NASA Laboratory. He is the Founding Director of PARADISE Research Lab at uOttawa. His current research interests include Wireless Networks and Mobile Computing, Wireless Ad hoc and Sensor Networks, Wireless Multimedia Sensor Networks, Distributed management and security system for wireless and mobile networks, and large-scale distributed interactive simulations and collaborative virtual environment.
He serves as an Associate Editor for the IEEE Transactions on Vehicular Technology, IEEE Transactions on Parallel and Distributed Systems, , IEEE Wireless Communication Magazine, ACM/Springer Wireless Networks, Elsevier Ad Hoc Networks, Elsevier Int'l Journal on Pervasive and Mobile Computing, Wiley's Wireless Communication and Mobile Computing Journal, the Int'l Journal of Parallel and Distributed Computing (JPDC), Wiley's Security and Communication Networks Journal and SCS Transactions on Simulation. He serves as a General Chair of the 8th IEEE WoWMoM2010, Program Co-Chair for IEEE ISCC 2009, IEEE Globecom 2008- and 2009 Ad Hoc, Sensor and Mesh Networking Symposium, ICPP 2008, and the Steering Committee Chair for ACM/IEEE MSWiM. IEEE/ACM DS-RT and NTMS Conferences.
He was the recipient of several awards, including ICC 2008 and ICC 2009,IWCMC 2010, and IEEE/ACM PADS Best Paper Awards, The Ontario Distinguished Researcher Award, the prestigious Premier's Ontario Research Excellence Award, and the George S. Glinski Award for Excellence in Research.
This talk will consist in an overview about the majore search projects related to wireless multimedia, context aware computing and wireless ad hoc and sensor networks, distributed and collaborative virtual environment, which we are currently investigating at PARADISE Research Laboratory, uOttawa. Next, we shall focus upon the design of large-scale distributed and mobile system for critical conditions monitoring class of applications using both location/context aware computing and wireless multimedia sensor and actor technologies. Then, we shall focus upon the security and localization problems in mobile and wireless multimedia sensor networks. Finally, if time permits, we will talk about LIVE testbed, a convergence of Wireless sensors, wireless multimedia and virtual environment technologies we are developing at PARADISE Research Laboratory for an emergency preparedness and response class of applications as well as SWiMNet, a high performance testbed we have developed which allows very detailed and realistic model specifications. It will facilitate and enable us to evaluate and design new protocols and applications for future generations of wireless sensor and vehicular network technologies.

Wolfgang Gentzsch, Open Grid Forum and DEISA Distributed European Initiative for Supercomputing Applications, Germany
Advances in e-Infrastructures for Computational Sciences and Engineering
Prof. Wolfgang Gentzsch is Dissemination Advisor for the DEISA Distributed European Infrastructure for supercomputing Applications, and a Member at Large of the Board of Directors of the Open Grid Forum. Until recently, he was an adjunct professor of computer science at Duke University in Durham, and a visiting scientist at RENCI Renaissance Computing Institute at UNC Chapel Hill, both in North Carolina. From 2005 to 2007, Dr. Gentzsch was the Chairman of the German D-Grid Initiative; Vice Chair of the e-Infrastructure Reflection Group e-IRG; Area Director of Major Grid Projects of the OGF Open Grid Forum Steering Group; and a member of the US President’s Council of Advisors for Science and Technology (PCAST). Before, he was Managing Director of the MCNC Grid and Data Center Services in North Carolina; Sun's Senior Director of Grid Computing in Menlo Park, CA; President, CEO, and CTO of HPC software companies Genias and Gridware, and a professor of mathematics and computer science at the University of Applied Sciences in Regensburg, Germany. Wolfgang Gentzsch studied mathematics and physics at the Technical Universities in Aachen and Darmstadt, Germany.
Over the last 50 years, computational sciences and engineering have advanced the development of new and ever faster and better computers, algorithms, and software tools, and vice versa, computers have advanced sciences. But the better the technologies the more demanding our computational science applications. This progress is everywhere, at the level of technologies and computer architectures, at the middleware level, at the algorithm and application level, and even at the level of computing paradigms, where we evolved from mainframes, to vector and parallel computers, to grids and clouds, recently. We successfully optimized our algorithms and mapped them to the underlying architecture, e.g. with overlapping communication with computation, better load balancing through domain decomposition into parallel processes, or using library routines optimized for the specific architecture and processors. In our presentation, we will concentrate on the use of grid and cloud technologies for HPC, focusing on the European EU-funded DEISA Distributed European Infrastructure for Supercomputing Applications project, analyzing different HPC loads and their suitability for grids and for clouds, and taking a closer look at lessons learned and recommendations on how to build sustainable e-Infrastructures for computational sciences and engineering in the future.
