Gary Lakner is a Staff Software Engineer for IBM Rochester on assignment in the ITSO. He is a member of the Blue Gene Support Team in the IBM Rochester Support Center, where he specializes in both Blue Gene hardware and software, as well as performs customer installations. Prior to joining the Blue Gene team, Gary supported TCP/IP communications on the IBM System i platform. Gary has been with IBM since 1998.
I-Hsin Chung is a Research Staff Member at the IBM Thomas J. Watson Research Center. His research interests include performance tuning, performance analysis, and performance tools. His experience includes designing and developing performance tools on IBM platforms such as IBM Power Systems on AIX and Linux, and the Blue Gene/L and Blue Gene/P systems. Prior to joining IBM Research, he received his Ph.D. in Computer Science from the University of Maryland, College Park in 2004.
Dr. Guojing Cong is a research staff member at the IBM Thomas J. Watson Research Center. His research interests include automation of performance analysis and tuning for scientific applications, as well as the design and analysis of parallel algorithms for large-scale graph problems. He is an expert in solving irregular combinatorial problems on parallel systems. He received his Ph.D. in computer engineering from the University of New Mexico in 2004 and soon after joined IBM Research.
Scott Fadden is a performance engineer on the General Parallel File System (GPFS) development team at IBM. He has more than 10 years experience designing and implementing solutions for enterprise analytics, ETL and Business intelligence from large data warehouses to grid computing. As a GPFS performance engineer he specializes in complex solution design and performance tuning.
Nicholas Goracke is a Software Engineer for IBM Rochester working on both the Blue Gene Functional Test Team and Performance Team. He specializes in Blue Gene debugger interface and Web GUI test, as well as development and design of the performance counter APIs. Nicholas joined IBM in 2005 after graduating from the University of Minnesota: Twin Cities with a Bachelor's degree in Computer Science.
David Klepacki is a senior staff member of IBM Research and has more than 20 years of experience in high performance computing (HPC). He currently manages the Advanced Computing Technology department at the IBM Thomas J. Watson Research Center. He earned a Ph.D. in theoretical nuclear physics from Purdue University and has since worked in a variety of technical areas within IBM including high-performance processor design, numerically intensive computation, computational physics, parallel computing, and performance modeling.
Jeffrey Lien is an Advisory Software Engineer for IBM Rochester and is a member of the Blue Gene performance team. He specializes in measuring and tuning IO performance for Blue Gene customers as well as running I/O benchmarks needed for customer bids. Prior to joining the Blue Gene performance team, Jeff developed and tested I/O device drivers used on Ethernet and modem adapter cards. Jeff has been with IBM since 1990.
Dr. Christoph Pospiech joined IBM in 1988 as a member of the IBM Scientific Center Heidelberg after completing his Ph.D. in applied mathematics at Heidelberg University. He has nearly 20 years of experience in the area of vector and parallel computing. Currently he is part of the Systems Technology Group, working on customer applications, mainly in the weather and climate area. He collaborated with the Advanced Computing Technology department at the IBM Thomas J. Watson Research Center on developing and maintaining tool components.
Seetharami R. Seelam is a post-doctoral research staff member at the IBM Thomas J. Watson Research Center in Yorktown Heights, NY, since 2007. He is a member of the IBM Advanced Computing Technologies Center, where he works on performance analysis tools and technologies for AIX on the IBM System p platform and Blue Gene systems as well as on next-generation automatic performance analysis, bottleneck detection, and solution determination technologies. He received a Ph.D. in Computer Science from the University of Texas at El Paso in 2006. His areas of interest are in HPC, operating systems, I/O, performance tools, and resource management.
Hui-Fang Wen is an Advisory Software Engineer at the IBM Thomas J. Watson Research Center. She is a member of the IBM Advanced Computing Technology Center, where she works on performance tools and the GUI design. She holds a Master's in Computer Science degree from University of Maryland, College Park. She has been with IBM since 2005.
