McInnes gives presentation at the Margaret Butler Celebration Event

June 17, 2015

Lois Curfman McInnes, a senior computational scientist in Argonne’s MCS Division, gave a presentation to highlight the achievements and impact of Margaret Butler at the inaugural “Margaret Butler Celebration of Women in Computational Science and Nuclear Engineering” on June 11.

McInnes spoke of Margaret’s remarkable career, from “computer”—a term used originally to describe a person performing computations—to computational scientist. “Margaret felt she was living in a time of incredible excitement and transformation,” said McInnes.

Margaret’s work at Argonne certainly reflected this excitement. In the early 1950s, for example, she helped design ORACLE, the world’s fastest computer at the time; and she worked on the logical design for AVIDAC and GEORGE, early computers based on the von Neumann architecture. McInnes noted that Margaret grappled with issues in reusable scientific software that still concern us today—most notably memory usage, portability, interoperability, and thorough testing.  Moreover, Margaret learned, then taught, computer architecture and programming before there were courses available in any schools on the subjects, as university computer science courses had not yet arrived.

In the 1960s and early 1970s, Margaret tackled several other areas hampering effective use of computers: benchmarking, performance measurement, and the lack of documentation for vendor-supplied software. These efforts led to her creation of the Argonne Code Center, which later expanded into the National Energy Software Center (NESC) —a central repository for the testing and exchange of DOE-sponsored codes; Margaret headed NESC until her retirement in 1991.

In recognition of her accomplishments, Margaret was the first female fellow of the American Nuclear Society. But McInnes stressed that Margaret’s contributions went much beyond her research accomplishments.  “She was an influential role model and mentor in the fullest sense,” said McInnes. Margaret was president of the Chicago Area Chapter of the Association of Women in Science in 1982.  Her work paved the way for the Argonne Women in Science and Technology (WIST) program, currently celebrating its 25th anniversary, see . Margaret also helped to establish Argonne’s Science Careers in Search of Women Conference, which inspires high school women to pursue careers in science, bringing them to Argonne for a day of lectures, tours, career booth exhibits, and mentoring, see .

McInnes also cited numerous examples of women scientists and postdoctoral researchers at Argonne today who are conducting cutting-edge research. “Margaret would be delighted and proud of them,” McInnes said.  

A featured speaker at the event was Ying Li, recipient of the first Margaret Butler Fellowship in Computational Science sponsored by the Argonne Leadership Computing Facility (ALCF). Li spoke about her research on simulations studying hydrogen production and storage for fuel cells and batteries using Mira, the ALCF’s IBM Blue Gene/Q supercomputer. 

The keynote speaker of the celebration was Dona Crawford, Associate Director for Computation, Lawrence Livermore National Laboratory, who discussed advancements in computer platforms over the last 60 years and the broad impact of high-performance computational science.  Her presentation was entitled #hpcmatters, after the SC14 promo youtube video that explains in simple terms just why HPC matters.

The Margaret Butler Celebration was presented by the ALCF and WIST program. More information about the inaugural celebration can be found at and at the ALCF website.
