Turing Award Winner On His Pioneering Algorithms

Jack Dongarra’s dream job rising up was to educate science at a public large college in Chicago.

“I was quite superior in math and science, but I was not a especially excellent scholar,” Dongarra states, laughing.

Following he graduated large university, there was only a person university he wanted to attend: Chicago Point out. That is due to the fact, he says, it was known for “churning out instructors.” Chicago Condition recognized his software, and he decided to main in arithmetic.


His physics professor suggested that Dongarra implement for an internship at the Argonne Nationwide Laboratory, in Lemont, Unwell., a nearby U.S. Section of Electrical power science and engineering exploration center. For 16 weeks he labored with a group of scientists coming up with and developing EISPACK, a deal of Fortran routines that compute the eigenvalues and eigenvectors of matrices—calculations widespread in scientific computing.

Dongarra acknowledges he didn’t have a qualifications in or know-how of eigenvalues and eigenvectors—or of linear algebra—but he liked what he was accomplishing. The knowledge at Argonne, he claims, was transformative. He had found his enthusiasm.

“I thought it was a interesting factor to do,” he says, “so I retained pursuing it.”

About Jack Dongarra

Employer: College of Tennessee, Knoxville

Title: Professor emeritus, computer science

Member grade: Daily life Fellow

Alma mater: Chicago Condition University

The IEEE Existence Fellow has given that built groundbreaking contributions to numerical algorithms and libraries for linear algebra, which authorized software program to make superior use of large-effectiveness components. His open-source program libraries are utilised in just about each individual computer system, from laptops to the world’s quickest supercomputers.

The libraries consist of essential linear algebra subprograms (BLAS), the linear-algebra deal LAPACK, parallel virtual devices (PVMs), immediately tuned linear algebra software (ATLAS), and the higher-effectiveness conjugate gradient (HPCG) benchmark.

For his do the job, he was honored this year with the 2021 A.M. Turing Award from the Affiliation for Computing Equipment. He obtained US $1 million as element of the award, which is regarded as the Nobel Prize of computing.

“When I imagine about earlier Turing Award recipients, I’m humbled to think about what I’ve figured out from their books and papers,” Dongarra claims. “Their programming languages, theorems, approaches, and criteria have assisted me produce my algorithms.

“It’s a large honor to be this year’s recipient. The award is a recognition by the computer system-science neighborhood that the contributions we are generating in large-performance computing are vital and have an impact in the broader computer-science local community and science in typical.”

Dongarra didn’t finish up training science to significant university pupils. Rather, he grew to become a professor of electrical engineering and personal computer science at the University of Tennessee in Knoxville, where he taught for 33 many years. The university recently named him professor emeritus.

Entrepreneurial Spirit

Following graduating from Chicago State in 1972 with a bachelor’s diploma in mathematics, Dongarra went on to go after a master’s degree in laptop or computer science at the Illinois Institute of Technological innovation, also in Chicago. Though there he worked a person day a 7 days for Argonne with the exact same staff of researchers. Following he obtained his diploma in 1973, the lab employed him full time as a researcher.

With encouragement from his colleagues to go after a Ph.D., he left the lab to study applied arithmetic at the College of New Mexico in Albuquerque. He honed his information of linear algebra there and started doing the job out algorithms and composing software.

He returned to Argonne after having his doctorate in 1980 and labored there as a senior scientist right until 1989, when he acquired the prospect to satisfy his aspiration of educating.

He was supplied a joint posture educating personal computer science at the College of Tennessee and conducting research at the nearby Oak Ridge Nationwide Laboratory which, like Argonne, is a Department of Vitality facility.

“It was time for me to try out some new matters,” he suggests. “I was all set to try my hand at academia.”

He says Oak Ridge operated in a related way to Argonne, and the culture there was more or less the very same.

“The obstacle,” he says, “was turning into a university professor.”

“The Turing Award is a recognition by the laptop or computer science community that the contributions we are producing in large-effectiveness computing are important, and have an impression in the broader laptop or computer science community and science in basic.”

College lifestyle is very various from that at a authorities laboratory, he claims, but he promptly fell into the rhythm of the educational placing.

Though he liked training, he suggests, he also was attracted to the prospect the college gave its instructors to function on technological innovation they are passionate about.

“You stick to your very own path and system of investigate,” he suggests. “I’ve prospered in that atmosphere. I interact with wise people today, I have the means to vacation all-around the earth, and I have collaborations going on with men and women in numerous nations around the world.

“Academia provides you this flexibility to do points and not be constrained by a company’s push or its determination. Instead, I get to work on what motivates me. That’s why I have stayed in academia for so many years.”

Dongarra launched the university’s Ground breaking Computing Laboratory, whose mission is to provide equipment for higher-general performance computing to the scientific group. He also directs the school’s Center for Info Technological know-how Study.

He is now a distinguished researcher at Oak Ridge, which he phone calls “a superb location, with its point out-of-the-art tools and the most recent desktops.”

Application for Supercomputers

It was functioning in inventive environments that led Dongarra to arrive up with what many describe as planet-altering application libraries, which have contributed to the development of high-efficiency computing in a lot of areas together with artificial intelligence, knowledge analytics, genomics, and overall health treatment.

“The libraries we created have essential factors that are necessary in a lot of spots of science so that users can attract on all those elements to enable them resolve their computational difficulties,” he states. “That software package is transportable and efficient. It has all the attributes that we want in phrases of remaining understandable and furnishing trustworthy results.”

He’s at the moment working on developing a software library for the world’s fastest supercomputer, Frontier, which lately was set up at the Oak Ridge lab. It is the initially pc that can procedure a lot more than 1 quintillion operations for every 2nd.

Laptop-Science Recognition

Dongarra has been an IEEE member for extra than 30 decades.

“I delight in interacting with the community,” he states in explaining why he continues to belong. “Also I take pleasure in studying IEEE Spectrum and journals that are related to my distinct subject.”

He has served as an editor for many IEEE journals together with Proceedings of the IEEE, IEEE Personal computer Architecture Letters, and IEEE Transactions on Parallel and Distributed Techniques.

Dongarra says he’s a major promoter of IEEE conferences and workshops, particularly the International Convention for Substantial Overall performance Computing, Networking, Storage, and Assessment, sponsored by ACM and the IEEE Laptop Modern society, of which he is a member. He’s been attending the event every 12 months due to the fact 1988. He has gained several awards at the conference for his papers.

“That convention is truly a homecoming for the substantial-efficiency computing neighborhood,” he suggests, “and IEEE plays a major job.”

IEEE is very pleased of Dongarra’s contributions to computing and has honored him about the years. In 2008 he acquired the very first IEEE Medal of Excellence in Scalable Computing. He also received the 2020 Laptop Pioneer Award, the 2013 ACM/IEEE Ken Kennedy Award, the 2011 IEEE Charles Babbage Award and the 2003 Sidney Fernbach Award.

“I’m extremely satisfied and proud to be a member of IEEE,” he says. “I assume it delivers a useful service to the local community.”
