Taylor and Wu win Best Paper Award

Dr. Xingfu Wu, TEES research scientist, and Dr. Valerie Taylor, the Royce E. Wisenbaker Professor in the Department of Computer Science and Engineering at Texas A&M University, won the Best Paper Award among 53 accepted papers in the 14th IEEE International Conference on Computational Science & Engineering in Dalian, China, Aug. 24-26.

Their paper title is "Performance Modeling of Hybrid MPI/OpenMP Scientific Applications on Large-scale Multicore Cluster Systems."

This work offers "a performance modeling framework based on memory bandwidth contention time and a parameterized communication model to predict the performance of OpenMP, MPI and hybrid applications with weak scaling on three large-scale multicore clusters: IBM POWER4, POWER5+ and BlueGene/P,...The experimental results for (their) performance modeling method showed less than 7.77 percent error rate in predicting the performance of hybrid and OpenMP GTC on up to 512 cores on the three multicore clusters."

He is a senior ACM member and an IEEE member. His research interests are performance evaluation and modeling, parallel and cloud computing, and power and energy analysis in HPC systems. His monograph, Performance Evaluation, Prediction and Visualization of Parallel Systems, was published by Kluwer Academic Publishers (ISBN 0-7923-8462-8) in 1999. Wu has published more than 28 papers since he joined Texas A&M's Department of Computer Science and Engineering in 2003. He obtained his Ph.D. degree from Beijing University of Aeronautics & Astronautics in March 1997.

Taylor earned her B.S. in electrical and computer engineeringPhoto of Dr. Valerie Taylorand M.S. in computer egineering from Purdue University, and a Ph.D. in electrical engineering and computer science from the University of California, Berkeley. From 1991 through 2002, Taylor was a member of the faculty in the Electrical and Computer Engineering Department at Northwestern University. Taylor joined the faculty of Texas A&M in 2003 as head of the Department of Computer Science, a position she held until 2011. Her research interests are in the area of high-performance computing. She has authored or co-authored more than 100 papers in these areas. Taylor is a member of ACM and Senior Member of IEEE-CS.
