An Overview of High Performance Computing and Future Requirements

Jack Dongarra
University of Tennessee Distinguished Professor
Monday November 12, 7:30pm
Jack Dongarra holds an appointment at the University of Tennessee, Oak Ridge National Laboratory, and the University of Manchester. He specializes in numerical algorithms in linear algebra, parallel computing, use of advanced-computer architectures, programming methodology, and tools for parallel computers. He was awarded the IEEE Sid Fernbach Award in 2004 for his contributions in the application of high performance computers using innovative approaches; in 2008 he was the recipient of the first IEEE Medal of Excellence in Scalable Computing; in 2010 he was the first recipient of the SIAM Special Interest Group on Supercomputing's award for Career Achievement; and in 2011 he was the recipient of the IEEE IPDPS 2011 Charles Babbage Award. He is a Fellow of the AAAS, ACM, IEEE, and SIAM and a member of the National Academy of Engineering. In this talk we examine how high performance computing has changed over the last 10 years and look toward the trends of the future. Recent changes have had, and will continue to have, a major impact on our numerical scientific 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. In this talk we will focus on the redesign of software to fit multicore architectures.

GPU Computing Now and Tomorrow

Steve Scott
Chief Technology Officer, NVIDIA Tesla Business Unit
Tuesday November 13, 11:00am
Dr. Steve Scott is Chief Technology Officer of the Tesla business unit at NVIDIA, where he is responsible for the evolution of NVIDIAÕs GPU computing roadmap. Prior to joining NVIDIA in August 2011, Steve spent 19 years at Cray, where he architected multiple systems and routers, and was CTO since 2004. Steve holds thirty-one US patents, and has served on numerous advisory boards and program committees. He was the recipient of the 2005 ACM Maurice Wilkes Award and the 2005 IEEE Seymour Cray Computer Engineering Award. He received his PhD in computer architecture in 1992 from the University of Wisconsin at Madison, where he was a Wisconsin Alumni Research Foundation and Hertz Foundation Fellow. GPU computing has made tremendous strides over the past decade, evolving from powerful, yet difficult-to-program GPGPUs, to the much more general and easily programmed computational accelerators of today. With the debut of the Titan system at ORNL, GPUs now power the worldÕs largest open science supercomputer, and have been widely adopted across a range of scientific and technical disciplines. This talk will discuss the motivation behind GPU computing, the current landscape, and how GPU computing is likely to evolve over the coming decade.

Toward an Distributed Cyberinfrastructure Ecosystem

John Towns
XSEDE PI and Project Director
University of Illinois
Tuesday November 13, 1:30pm
John Towns is Director of Collaborative Cyberinfrastructure Programs at the National Center for Supercomputing Applications (NCSA) at the University of Illinois. He is also PI and Project Director for the Extreme Science and Engineering Discovery Environment (XSEDE) project. Towns plays significant roles in the deployment and operation of high-end resources and Grid-related projects and is also PI on awards for various resources operated at NCSA. His background is in computational astrophysics utilizing a variety of computational architectures with a focus on application performance analysis. At NCSA, he provides leadership and direction in the support of an array of computational science and engineering research projects making use of advanced computing resources and services. He earned M.S. degrees in Physics and Astronomy from the University of Illinois and a B.S in Physics from the University of Missouri Rolla. The state of the art of digital systems supporting the pursuit of research has been a rapidly evolving target for many years. Still, the community is reaching an inflection point in transitioning from the focus of individual resources and services to a more integrated view of how services, resources and support are coordinated in creating an environment that enhances the productivity of researchers. A natural consequence of this is the need to support the integration of resources and services delivered by providers who are in a spectrum of administrative domains. I will briefly introduce the XSEDE project and make some observations and comments on the need for type of distributed cyberinfrastructure ecosystem that XSEDE is developing in order to facilitate research.

In the event of a toxic release in an urban environment situational awareness is critical to expedite evacuation and reduce the risk to first responders. Major computing facilities are a great asset that could be used to make reasonable and timely projection of where the local wind and weather conditions might take the resulting toxic plume and how the traffic might be routed to aid the safe movement of people out of harms way. Timeliness is vital in these circumstances and the talk will discuss the problem and current progress in providing detailed plans to manage the event using current and projected HPCC systems.
