ECE Distinguished Speaker Series: An Overview of High-Performance Computing and Future Requirements

SPEAKER: Turing Award winner Jack Dongarra of Oak Ridge National Laboratory ABOUT Prof. DONGARRA: 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 is a Fellow of AAAS, ACM, IEEE, and SIAM, a foreign fellow of the British Royal Society and a member of the US National Academy of Engineering. ABSTRACT: In this talk we examine how high performance computing has changed over the last ten years and look toward the future in terms of trends. These changes have had and will continue to impact our numerical scientific software significantly. 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.
