From eardrums to electromagnetics, Demkowicz hears the problems

From eardrums to electromagnetics, Demkowicz hears the problems

A good tool is both robust and accurate; it doesn’t break down easily, or give faulty readings or results. This standard applies to everything from a bathroom scale, or vending machine to a sniper rifle. It also rings true for computer code.

Industry and agencies use computer code to design products and test research in the digital realm. It cuts down and time and cost, and can allow a design to be tested in a variety of conditions. Teams of scientists and engineers at companies are dedicated to implementing codes that work efficiently and represent reality—codes that are robust and accurate. But sometimes, they get stuck.

Demkov receives a 2011 IBM Faculty Award

ICES Professor Alex Demkov has received a 2011 IBM Faculty Award.

Demkov, an associate professor of physics affiliated with the ICES Center for Computational Materials, received one of only two awards for work in the physics category and the only award granted to UT Austin. The funds will be used in Demkov’s Materials Physics Lab to support his team’s research on epitaxial oxides.

His group mostly works with perovskites (materials with the chemical formula ABO3, where A is alkaline earth and B a transition metal, SrTiO3 is an example). These show a wide range of interesting physical properties from ferroelectricity to ferromagnetism and superconductivity. Demkov has established a particular niche in the integration of these functional materials with semiconductors such as Si. Read more.

Keshav Pingali Helps Guide New Center for Cloud Computing

ICES’ Keshav Pingali and Computer Science Department Chair Bruce Porter will serve on the executive committee guiding a new center for cloud computing research.

As part of research to help create safer and faster computing, the Department of Computer Science has partnered with SunGard Availability Services to improve emerging cloud-based technologies.

Pingali, director of the ICES Center for Grid and Distributed Computing, has patented technology currently in use by industry.

The Cloud Computing Research Center will give the university and SunGard the ability to work together to identify relevant research problems in cloud computing, pursue research initiatives to solve those problems and, as appropriate, commercialize the resulting research. Read more.

Robert van de Geijn's libflame library successfully used by TI

Setting a milestone in multicore innovation, Texas Instruments and ICES' Robert van de Geijn have successfully ported UT Austin's libflame library, a dense linear algebra library for scientific computing, to TI's TMS320C6678 multicore digital signal processor (DSP).

This port delivers all of libflame's functionalities, providing fundamental software building blocks for many high performance computing applications such as oil and gas exploration, financial modeling and molecular dynamics.

The announcement was made during SC 2011, the International Conference for High Performance Computing, Networking, Storage and Analysis held this year in Seattle. Read more.

Ali Yilmaz studies health affects of wireless devices

What are the effects of all these nearby wireless devices on us? That’s the question Dr. Ali Yilmaz is exploring with Dr. Leszek Demkowicz and other ICES researchers.

Using a National Science Foundation (NSF) five-year, interdisciplinary grant, the group seeks to address the growing debate about the effects of microwave radiation. After two years, Electrical & Computer Engineering Assistant Professor Ali Yilmaz and his colleagues have built one of the highest-resolution electromagnetic human models to date: AustinMan. The model is helping to determine the effects of microwaves from wireless devices on the body. Read more.
