James C. Browne

Browne is Professor Emeritus of Computer Science and Physics at The University of Texas at Austin. Browne earned his Ph.D. in Chemical Physics at The University of Texas in 1960 Browne's current research interests span parallel programming and computation, performance optimization, software engineering, formal methods and fault/failure management for complex systems.

Browne has attained Fellow status in five professional societies and areas: The Association for Computing Machinery, the British Computer Society, the American Physical Society, the American Association for the Advancement of Science and the Institute for Constructive Capitalism. Browne has published approximately 100 papers in computational physics and 250 papers in Computer Science.

Browne received the 2004 University of Texas at Austin Career Research Excellence Award for maintaining a superior research program in such fields as parallel computation, performance measurement and analysis, operating systems, and software engineering for a long time span. Browne has also been active in technology transfer and the technology industry. He founded Hyperformix, an Austin Texas based software company which sells products and services for performance management and engineering for enterprise level computer systems. Hyperformix was acquired by Computer Associates in October, 2010.

Leonardo Fialho

Leonardo Fialho was doing research on fault tolerance for MPI applications at the University Autonoma of Barcelona, Spain, where he obtained an MSc and PhD degrees. Hist first posdoctoral position was at Dublin City University (DCU), Ireland, doing research on power efficiency for telecommunication networks. Currently, Leonardo is an associate researcher at the Texas Advanced Computing Center at the University of Texas at Austin.

Ashay Rane

Ashay Rane is a PhD student in the Computer Science department at the University of Texas at Austin. Prior to joining the PhD program in the Fall of 2012, he researched, developed and maintained PerfExpert from December 2010 until August 2012. His experience with performance optimization dates back his Master's degree in Computer Science at Arizona State University, which resulted in a thesis titled, "A Study of the Hybrid MPI/OpenMP Programming Paradigm on Multicore Architectures". His areas of interest include compilers, computer architecture and performance tuning.
