Piyush Mehrotra: "HPC and Data Analysis at NASA Ames."

Abstract: This talk will describe the High-Performance Computing (HPC) and data analysis & visualization resources available at the NASA Advanced Supercomputing (NAS) Division to enable large scale modeling and simulations required to tackle some of the toughest science and engineering challenges facing NASA today. The talk will also highlight some of the projects that involve analysis and analytics of large data sets.

Bio: Piyush Mehrotra is Chief of the NASA Advanced Supercomputing (NAS) Division at NASA Ames Research Center, and oversees the full range of high-performance computing services for NASA's primary supercomputing center. He also manages NAS's modeling and simulation research and development efforts, which are critical for numerous agency missions. Piyush's key responsibilities are setting high-level objectives for the division, creating and maintaining a productive, high-impact computational facility, and coordinating technical strategy with both NASA Ames and NASA Headquarters management. This work encompasses managing about 150 Research and Development (R&D) scientists, engineers, and support staff comprised of civil servants and contractors. In addition, he is the manager of the NASA Earth Exchange (NEX) Project.

Piyush is a world-renowned expert with over 30 years of R&D experience in parallel programming languages, including compilers and runtime systems for shared and distributed memory systems, and middleware infrastructure for grid environments. He is also experienced in performance characterization and benchmarking of parallel architectures. He has published over 100 articles in journals and conferences, edited two books, and served as editor for several issues of international computer science journals. Previously, Piyush served as Chief of the NAS Computational Technologies Branch and Lead of the Application Performance and Productivity (APP) Group. He has held various other technical and managerial positions since joining NASA Ames Research Center in 2000. During this time, he has received several NASA awards, including the Outstanding Leadership Medal in 2010 and several group achievement awards. Previously, he was an Assistant Professor in Purdue University's Computer Science Department and rose through the ranks at the International Council of Associations for Science Education (ICASE), the Institute for Computer Applications in Science and Engineering, to become a Research Fellow, managing their computer science program. He obtained his Ph.D. in Computer Science from the University of Virginia in 1982.
