RCE an HPC Podcast
Brock Palen and Jeff Squyres speak with Boyana Norris about Orio. An open-source extensible framework for the definition of domain-specific languages and generation of optimized (C, Fortran, CUDA, OpenCL) code for multiple architecture targets (e.g., CPUs, NVIDIA and AMD GPUs, Intel Phi), including support for empirical autotuning of the generated code.
Boyana Norris received her B.S. in Computer Science at Wake Forest University in 1995 and her Ph.D. in Computer Science from the University of Illinois at Urbana-Champaign in 2000. She joined Argonne National Laboratory as a postdoctoral researcher in 1999 and continued working there through 2013 as an Assistant Computer Scientist and Computer Scientist. She is currently an Assistant Professor at the Department of Computer and Information Science at the University of Oregon. Her research in high-performance computing (HPC) focuses on methodologies and tools for performance reasoning and automated optimization of scientific applications, while ensuring continued or better usability of HPC tools and libraries and improving developer productivity. She has coauthored over 70 peer-reviewed publications on topics including performance modeling, automated performance optimization (autotuning) of parallel scientific applications, embedding of domain-specific languages into legacy codes, source-transformation-based automatic differentiation, adaptive algorithms for HPC, component-based software engineering for HPC, and taxonomy-based approaches to learning and using HPC libraries. In her computer-free time, Boyana likes to run unreasonable distances, read, garden, and spend time with her family.

Steven Tuecke is Deputy Director of the Computation Institute (CI) at The University of Chicago and Argonne National Laboratory, and co-leads the Globus project with Dr. Ian Foster. His focus is on the development of sustainable, cloud-based, software-as-a-service data management solutions to accelerate research. Prior to CI, Steven was co-founder, CEO and CTO of Univa Corporation from 2004-2008, providing open source and proprietary software for the high-performance computing and cloud computing markets. Before that, he spent 14 years at Argonne as research staff. Tuecke graduated summa cum laude with a B.A in mathematics and computer science from St. Olaf College.
Brock Palen and Jeff Squyres speak with Brad Chamberlain and Sung-Eun Choi from Cray about Chapel. Chapel is designed to improve the productivity of high-end computer users while also serving as a portable parallel programming model that can be used on commodity clusters or desktop multicore systems.
Bradford Chamberlain is a Principal Engineer at Cray Inc. where he works on parallel programming models, focusing primarily on the design and implementation of the Chapel language in his role as technical lead for that project. Brad received his Ph.D. in Computer Science & Engineering from the University of Washington in 2001 where his work focused on the design and implementation of the ZPL parallel array language. In the past, he has also worked on languages for embedded reconfigurable processors and on algorithms for accelerating the rendering of complex 3D scenes. Brad remains associated with the University of Washington as an affiliate faculty member and is currently teaching a Professional Masters course on Parallel Computation. He received his Bachelor's degree in Computer Science with honors from Stanford University in 1992.
Sung-Eun Choi is currently a member of the Chapel group at Cray, Inc. in Seattle, WA. Before joining the Chapel group, she was the lead runtime developer for the Cray XTM (TM) system, a full-custom massively multithreaded computer system. Prior to that, she worked on scalable system software in the Advanced Computing Laboratory at Los Alamos National Laboratory. Sung-Eun holds a Ph.D. in Computer Science from the University of Washington in Seattle.
