An Overview of High Performance Computing and Challenges for the Future
Jack Dongarra
University of Tennessee and Oak Ridge National Laboratory

In this talk we examine how high performance computing has changed over the last 10-year and look toward the future in terms of trends. These changes have had and will continue to have a major impact on our software. A new generation of software libraries and algorithms are needed for the effective and reliable use of (wide area) dynamic, distributed and parallel environments. Some of the software and algorithm challenges have already been encountered, such as management of communication and memory hierarchies through a combination of compile--time and run--time techniques, but the increased scale of computation, depth of memory hierarchies, range of latencies, and increased run--time environment variability will make these problems much harder.
We will focus on the redesign of software to fit multicore architectures.

Jack Dongarra received a Bachelor of Science in Mathematics from Chicago State University in 1972 and a Master of Science in Computer Science from the Illinois Institute of Technology in 1973. He received his Ph.D. in Applied Mathematics from the University of New Mexico in 1980. He worked at the Argonne National Laboratory until 1989, becoming a senior scientist. He now holds an appointment as University Distinguished Professor of Computer Science in the Computer Science Department at the University of Tennessee and holds the title of Distinguished Research Staff in the Computer Science and Mathematics Division at Oak Ridge National Laboratory (ORNL), Turning Fellow at Manchester University, and an Adjunct Professor in the Computer Science Department at Rice University. He is the director of the Innovative Computing Laboratory at the University of Tennessee. He is also the director of the Center for Information Technology Research at the University of Tennessee which coordinates and facilitates IT research efforts at the University. He specializes in numerical algorithms in linear algebra, parallel computing, the use of advanced-computer architectures, programming methodology, and tools for parallel computers. His research includes the development, testing and documentation of high quality mathematical software. He has contributed to the design and implementation of the following open source software packages and systems: EISPACK, LINPACK, the BLAS, LAPACK, ScaLAPACK, Netlib, PVM, MPI, NetSolve, Top500, ATLAS, and PAPI. He has published approximately 200 articles, papers, reports and technical memoranda and he is coauthor of several books. He was awarded the IEEE Sid Fernbach Award in 2004 for his contributions in the application of high performance computers using innovative approaches and in 2008 he was the recipient of the first IEEE Medal of Excellence in Scalable Computing. He is a Fellow of the AAAS, ACM, and the IEEE and a member of the National Academy of Engineering.

Keynote speaker #2

Research and Development on WSN Node Architecture and Its Tools
Kougen Zheng
College of Computer Science, Zhejiang University

Despite the simplicity of the sensor node hardware, WSN applications are diverse and demanding. Infrastructural support for WSN applications in the form of WSN node architecture is becoming increasingly important. In this talk, the challenges of WSN node architecture will be pointed out. The new node architecture including OS and its language and its supporting tools would be described. Then, the key issues such as light-weight schedulingļ¼Œdata dissemination, memory allocator, concurrency model and module configuration would be investigated and the solution approaches would be described. Finally, the application of this new node architecture is demonstrated.

Kougen Zheng received his Ph.D. degree from University of Warwick, UK, in 1992. He is currently a professor of Computer Science College, Zhejiang University. His research interests include operating systems, computer networks, and trustworthy computing.
Dr. Zheng is the chief developer and investigator for numerous scientific and technical projects about pervasive computing, sensor networks, embedded systems, such as the National High Technology Research and Development Program(863 Program) of China, "Key technologies research on operating system support for Pervasive Computing", the National Basic Research Program of China (973 Program) "Research on node architecture for Wireless Sensor Networks", National Key Project "Product innovation of computer-aided design technologies and systems" and etc.
He has gained many awards such as the national scientific and technological progress second-class prize awarded by the People's Republic of China State Council as the participant of the project "Product innovation of computer-aided design technologies and systems", the first-class prize of scientific and technological progress of Zhejiang Province as participant of the project "New product development supporting regional economic development technologies and systems", and etc. In recent years, he has published more than 30 academic papers.
