Turing Award Winner On His Pioneering Algorithms

Jack Dongarra’s aspiration task growing up was to teach science at a general public substantial university in Chicago.

“I was really very good in math and science, but I wasn’t a significantly fantastic student,” Dongarra states, laughing.

Following he graduated superior university, there was only a person university he needed to go to: Chicago State. That is simply because, he suggests, it was recognized for “churning out teachers.” Chicago State accepted his application, and he made the decision to major in arithmetic.


His physics professor instructed that Dongarra implement for an internship at the Argonne Nationwide Laboratory, in Lemont, Unwell., a close by U.S. Department of Electricity science and engineering study heart. For 16 weeks he worked with a group of scientists planning and producing EISPACK, a offer of Fortran routines that compute the eigenvalues and eigenvectors of matrices—calculations popular in scientific computing.

Dongarra acknowledges he didn’t have a track record in or knowledge of eigenvalues and eigenvectors—or of linear algebra—but he loved what he was undertaking. The experience at Argonne, he suggests, was transformative. He had discovered his enthusiasm.

“I believed it was a awesome detail to do,” he suggests, “so I kept pursuing it.”

About Jack Dongarra

Employer: College of Tennessee, Knoxville

Title: Professor emeritus, personal computer science

Member quality: Daily life Fellow

Alma mater: Chicago Point out College

The IEEE Daily life Fellow has due to the fact created pioneering contributions to numerical algorithms and libraries for linear algebra, which authorized program to make great use of significant-general performance hardware. His open-source software libraries are utilised in just about every computer, from laptops to the world’s speediest supercomputers.

The libraries involve essential linear algebra subprograms (BLAS), the linear-algebra offer LAPACK, parallel virtual equipment (PVMs), quickly tuned linear algebra software (ATLAS), and the significant-overall performance conjugate gradient (HPCG) benchmark.

For his do the job, he was honored this 12 months with the 2021 A.M. Turing Award from the Affiliation for Computing Machinery. He been given US $1 million as section of the award, which is acknowledged as the Nobel Prize of computing.

“When I consider about past Turing Award recipients, I’m humbled to imagine about what I’ve learned from their guides and papers,” Dongarra states. “Their programming languages, theorems, techniques, and criteria have served me produce my algorithms.

“It’s a incredible honor to be this year’s recipient. The award is a recognition by the personal computer-science group that the contributions we are building in high-effectiveness computing are important and have an affect in the broader laptop-science local community and science in common.”

Dongarra did not end up educating science to significant university pupils. Instead, he turned a professor of electrical engineering and laptop or computer science at the University of Tennessee in Knoxville, wherever he taught for 33 decades. The college just lately named him professor emeritus.

Entrepreneurial Spirit

Immediately after graduating from Chicago State in 1972 with a bachelor’s diploma in mathematics, Dongarra went on to pursue a master’s degree in computer system science at the Illinois Institute of Technology, also in Chicago. When there he worked 1 working day a week for Argonne with the similar group of researchers. Just after he acquired his diploma in 1973, the lab hired him entire time as a researcher.

With encouragement from his colleagues to pursue a Ph.D., he still left the lab to analyze used arithmetic at the University of New Mexico in Albuquerque. He honed his awareness of linear algebra there and began operating out algorithms and creating software program.

He returned to Argonne after receiving his doctorate in 1980 and labored there as a senior scientist right up until 1989, when he got the prospect to satisfy his dream of teaching.

He was presented a joint placement educating pc science at the College of Tennessee and conducting exploration at the nearby Oak Ridge Countrywide Laboratory which, like Argonne, is a Division of Power facility.

“It was time for me to try out out some new factors,” he states. “I was prepared to try my hand at academia.”

He suggests Oak Ridge operated in a equivalent way to Argonne, and the society there was far more or much less the exact.

“The problem,” he says, “was starting to be a university professor.”

“The Turing Award is a recognition by the laptop science community that the contributions we are generating in significant-functionality computing are vital, and have an influence in the broader computer system science group and science in common.”

College tradition is quite unique from that at a government laboratory, he suggests, but he speedily fell into the rhythm of the tutorial location.

Although he loved educating, he suggests, he also was attracted to the prospect the college gave its instructors to function on know-how they are passionate about.

“You adhere to your personal path and training course of exploration,” he claims. “I’ve prospered in that atmosphere. I interact with sensible folks, I have the capability to travel all over the planet, and I have collaborations going on with persons in a lot of nations around the world.

“Academia presents you this independence to do matters and not be constrained by a company’s drive or its inspiration. Fairly, I get to operate on what motivates me. Which is why I’ve stayed in academia for so lots of years.”

Dongarra launched the university’s Modern Computing Laboratory, whose mission is to give tools for significant-efficiency computing to the scientific community. He also directs the school’s Center for Details Technological innovation Investigate.

He is now a distinguished researcher at Oak Ridge, which he phone calls “a great location, with its point out-of-the-art gear and the latest computer systems.”

Program for Supercomputers

It was operating in innovative environments that led Dongarra to arrive up with what lots of explain as planet-switching software package libraries, which have contributed to the growth of higher-effectiveness computing in several places such as artificial intelligence, info analytics, genomics, and health care.

“The libraries we built have primary components that are wanted in several spots of science so that buyers can attract on all those elements to assistance them fix their computational difficulties,” he states. “That software package is moveable and economical. It has all the attributes that we want in terms of being easy to understand and delivering responsible success.”

He’s presently doing work on developing a application library for the world’s fastest supercomputer, Frontier, which lately was set up at the Oak Ridge lab. It is the initial computer system that can method much more than 1 quintillion functions per next.

Personal computer-Science Recognition

Dongarra has been an IEEE member for a lot more than 30 years.

“I appreciate interacting with the local community,” he claims in conveying why he continues to belong. “Also I get pleasure from examining IEEE Spectrum and journals that are suitable to my specific subject.”

He has served as an editor for a number of IEEE journals including Proceedings of the IEEE, IEEE Laptop Architecture Letters, and IEEE Transactions on Parallel and Dispersed Programs.

Dongarra suggests he’s a big promoter of IEEE meetings and workshops, especially the International Meeting for Higher Efficiency Computing, Networking, Storage, and Evaluation, sponsored by ACM and the IEEE Pc Culture, of which he is a member. He’s been attending the function every calendar year due to the fact 1988. He has received a lot of awards at the meeting for his papers.

“That meeting is definitely a homecoming for the significant-effectiveness computing group,” he claims, “and IEEE plays a main job.”

IEEE is happy of Dongarra’s contributions to computing and has honored him about the a long time. In 2008 he been given the 1st IEEE Medal of Excellence in Scalable Computing. He also received the 2020 Computer Pioneer Award, the 2013 ACM/IEEE Ken Kennedy Award, the 2011 IEEE Charles Babbage Award and the 2003 Sidney Fernbach Award.

“I’m pretty satisfied and happy to be a member of IEEE,” he says. “I assume it delivers a beneficial services to the neighborhood.”
