The Variability Expeditions: Exploring the Software Stack for Underdesigned Computing Machines

Speaker: Rajesh K. Gupta, Professor and Qualcomm Endowed Chair in Embedded Microsystems, Department of Computer Science and Engineering, University of California, San Diego

Date: October 19, 2011

Time: 1:10 p.m.

Location: Alliant Energy – Lee Liu Auditorium, Howe Hall

Abstract: Modern computing is ignorant of the variability in the behavior of underlying components from device to device, chip to chip, its wear over time, or the environment in which the computing system is placed. This is a growing problem, as microelectronic devices scale down to molecular assemblies. The ‘guardbands’ used to guarantee component behavior (for power, performance) have gone to ridiculous margins accounting for as much as two-thirds of the chip area to meet performance ‘specs’ and is already undermining the gains from continued device scaling. Changing the way software interacts with hardware offers the best hope to recover the advantages from process scaling. In this this talk, Gupta will describe his approach and progress in the Variability Expeditions project that fundamentally rethinks the rigid, deterministic hardware-software interface, to propose a new class of computing machines that rely on an opportunistic software stack to adapt to the conditions in an underdesigned hardware.

Speaker biography: Gupta is a professor and Qualcomm Endowed Chair in Embedded Microsystems in the Department of Computer Science and Engineering at the University of California, San Diego (UCSD). His research interests are in energy efficient systems. Gupta leads the Microelectronic Embedded Systems Lab and is head of the Embedded Systems Group at UCSD. His recent contributions include SystemC modeling and SPARK parallelizing high-level synthesis, both of which are publicly available and have been incorporated into industrial practice. Gupta has led or co-lead Defense Advanced Research Projects Agency-sponsored efforts under the Data Intensive Systems and Power Aware Computing and Communications programs. Gupta received a bachelor’s degree in electrical engineering from Indian Institute of Technology, Kanpur, a master’s degree in electrical engineering and computer science from the University of California, Berkeley, and a PhD in electrical engineering from Stanford University. Gupta is a Fellow of IEEE.

Computer Science/Statistics Joint Lecture

Seminar: In-situ Computing

Speaker: Michael Coen, Department of Biostatistics & Medical Informatics and Department of Computer Science, University of Wisconsin-Madison

Date: October 17, 2011

Time: 4:10 p.m.

Location: 1312 Hoover Hall

Abstract: My work addresses a new framework for data analysis that bridges statistics, optimization theory, and machine learning. I introduce a family of computational methods that are heavily tied to the shapes and densities of datasets. This approach is visual and intuitive, while being mathematically formal, non-parametric, and distribution free. Applications are broad, including: medical informatics and imaging; clustering; protein homology; spatial-based kernels; and a new class of highly powerful goodness-of-fit and hypothesis tests. This talk will focus on both the theory and applications of this work, specifically examining some of its novel mathematical techniques. No prior background is assumed. (This work is joint with Hidayath Ansari, Marissa Phillips, and Timothy Chang.) 

Speaker bio: Mike Coen is an assistant professor at UW-Madison. His primary research interest is self-supervised machine learning, based on biologically inspired models of learning in animals. His Ph.D., S.M, and S.B. degrees are from MIT, where his doctoral thesis received the Sprowls Award for best dissertation in Computer Science.

This lecture was made possible in part by the generosity of F. Wendell Miller, who left his entire estate jointly to Iowa State University and the University of Iowa. Mr. Miller, who died in 1995 at age 97, was born in Altoona, Illinois, grew up in Rockwell City, graduated from Grinnell College and Harvard Law School and practiced law in Des Moines and Chicago before returning to Rockwell City to manage his family’s farm holdings and to practice law. His will helped to establish the F. Wendell Miller Trust, the annual earnings on which, in part, helped to support this activity.

Seminar: Efficient Electromagnetic Approaches for Developing Effective Medium Model for Semiconductor Substrates

Speaker: Associate Professor Jiming Song

Date: October 17, 2011

Time: 1:10 to 2 p.m.

Location: 3043 ECpE Building Addition

Abstract: Current CMOS and RFCMOS processes require substrate backend dummification. Modeling such structures using existing full wave electromagnetic simulation is very memory-intensive and almost impossible even at small die sizes. We develop a faster and memory-efficient electromagnetic full wave simulation tool to model a silicon backend and a multilayer organic package substrate with an effective medium model. This effective model provides the key building block to study die/package interaction, components to components interaction as well as die to die interaction in multichip modules.

First, I will give an overview of the research in computational electromagnetics in my group. Then I will present two efficient approaches to model metal lines/patches in multilayered media as an effective medium. The integral equation approach is developed to analyze the wave propagation in periodic structures. The approach is capable of handling scattering from the array filled with different media in different layers. Combining the equivalence principle algorithm and connection scheme (EPACS), it can be avoided to find and evaluate the multilayered periodic Green’s functions. The spectral domain approach is applied to analyze shielded microstrip over lossy layered media and the equivalent model is developed to replace the layered media with a single layer. Several approaches have been developed to accelerate the summation of infinite series in the evaluation of the matrix elements.

Speaker bio: Associate Professor Jiming Song received his PhD degree in electrical engineering from Michigan State University in 1993. From 1993 to 2000, he worked as a postdoctoral research associate, a research scientist, and visiting assistant professor at the University of Illinois at Urbana-Champaign. From 1996 to 2000, he worked as a research scientist at SAIC-DEMACO. Dr. Song was the principal author of the Fast Illinois Solver Code (FISC).  He was a principal staff engineer/scientist at the Semiconductor Products Sector of Motorola in Tempe, Arizona before he joined the Department of Electrical and Computer Engineering at Iowa State University as an assistant professor in 2002.

His research has dealt with modeling and simulations of interconnects on lossy silicon and RF components, the wave scattering using fast algorithms, the wave propagation in metamaterials, and transient electromagnetic field. Song received the NSF Career Award in 2006, and he is a senior member of IEEE.
