David Donofrio

David Donofrio—a veteran Computer Systems Engineer at Berkeley Lab—has been selected to lead the new Computer Architecture Group in the Computational Research Division (CRD). The group’s mission is to research, design and implement new architectural simulation capabilities, novel hardware architecture features, assess design trade-offs, and facilitate the co-design process for leading-edge high performance computing (HPC) systems.

Donofrio’s Berkeley Lab career began in 2008, when he joined the National Energy Research Scientific Computing Center’s (NERSC’s) Advanced Technologies Group to work on the Green Flash and CoDEX (Co-Design for Exascale) projects. His work focused on the design of large scale, power efficient, parallel computing architectures based on small, low-powered embedded processors that may one-day break the exaflop barrier and run next-generation scientific codes.

Before coming to Berkeley Lab, Donofrio spent six years at Intel Corporation as a computer architect, where he helped design the next-generation of integrated 3D graphics processors for Intel’s chipsets. He holds 6 patents on the design of the floating point for the GMA graphics processor. In 2011, he left Berkeley Lab to work as a Senior Performance Analyst of all Mac computers—including iMac, MacBook, MacAir, MacPro, etc.—at Apple Inc. But, he returned to Berkeley Lab’s Future Technologies Group in 2012 to join the Computer Architecture Laboratory (CAL) to work on the design and simulation of exascale class HPC systems. His research spans many types of architectures, including System-on-Chip design for HPC to real-time signal processing for neuroscience research.

John Shalf, who heads CRD’s Computer Science Department, notes that Donofrio’s long-standing interest in computer architecture and performance, as well as his understanding of the computing problems at Berkeley Lab and the Department of Energy make him an ideal candidate to lead the Computer Architecture group.

“Berkeley and Sandia are the National Labs leading the architecture part of DOE’s exascale research portfolio, and the Computer Architecture Group is central to this work. Dave’s experience and leadership will be a great asset to the team,” says Shalf.

Donofrio currently has eight patents in computer architecture.


About Computing Sciences at Berkeley Lab

The Lawrence Berkeley National Laboratory (Berkeley Lab) Computing Sciences organization provides the computing and networking resources and expertise critical to advancing the Department of Energy's research missions: developing new energy sources, improving energy efficiency, developing new materials and increasing our understanding of ourselves, our world and our universe.

ESnet, the Energy Sciences Network, provides the high-bandwidth, reliable connections that link scientists at 40 DOE research sites to each other and to experimental facilities and supercomputing centers around the country. The National Energy Research Scientific Computing Center (NERSC) powers the discoveries of 6,000 scientists at national laboratories and universities, including those at Berkeley Lab's Computational Research Division (CRD). CRD conducts research and development in mathematical modeling and simulation, algorithm design, data storage, management and analysis, computer system architecture and high-performance software implementation. NERSC and ESnet are DOE Office of Science User Facilities.

Lawrence Berkeley National Laboratory addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the DOE’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit science.energy.gov.
