A community laptop scientist and professor at the College of Tennessee at Knoxville has been named an A.M. Turing Award winner by the Association for Computing Machinery.
The Turing Award is generally referred to as the “Nobel Prize of laptop or computer science.” It carries a million dollar prize.
“Oh, it was a finish shock. I’m nevertheless recovering from it,” Jack Dongarra instructed Knox Information with a warm giggle. “It’s great to see the function being identified in this way but it couldn’t have occurred with no the help and contribution of quite a few persons about time.”
Odds are Dongarra’s work has touched your life, even if you really don’t know it. If you have ever used a speech recognition program or looked at a temperature forecast, you are working with engineering that depends on Dongarra’s software package libraries.

Dongarra has held a joint appointment at the College of Tennessee and Oak Ridge Countrywide Laboratory considering the fact that 1989. Even though he does not have a household name, his foundational do the job in laptop science has undergirded the enhancement of substantial-efficiency pcs more than the study course of his 40-calendar year career.
“I want to develop into a purpose design as quite a few of the other recipients have been for the future era of laptop scientist,” Dongarra said.
If you have a multicore personal computer (and you almost certainly do mainly because almost everything is multicore now) or use a graphics card, you’re relying on Dongarra’s code. The macOS and iOS operating system, scientific simulations and mathematical computer software like MatLab or Maple all count on versions of Dongarra’s program libraries.
“Jack Dongarra’s contributions to software program deals and libraries have been seminal in driving progress and innovations in computer system science and innovation in a spectrum of programs,” said Thomas Zacharia, director of Oak Ridge National Laboratory. “Whether it’s vitality protection, countrywide safety … at the core are his fundamental contributions in used arithmetic.”
In the late 1970s, Dongarra was a researcher at Argonne National Laboratory in close proximity to Chicago. He had just determined to go into pc science complete-time immediately after contemplating a profession as a teacher. Even though there, Dongarra assisted create an open-supply program library referred to as LINPACK.
LINPACK permitted the supercomputers of the working day to resolve linear algebraic problems with large effectiveness. Which is crucial since desktops are in essence massive calculators. As the calculations get more intricate, it truly is really significant that computers can retail store and crunch figures quickly and precisely.
“When you seem at determining which path to pick out with your GPS, there is this factor of information processing,” said Michela Taufer, a professor of pc science at the College of Tennessee at Knoxville. “The essential, atomic component of automated choice producing are vectors and matrixes. Those functions are finished by linear algebra.”
Linear algebra software libraries like LINPACK authorized experts to run a lot of calculations concurrently. Then, they can run simulations of all the things from temperature devices to nuclear meltdowns.
“If you are fixing an engineering challenge, you could have equations with hundreds of 1000’s of information details,” explained Horst Simon, previous deputy director of the Lawrence Ber
kley National Laboratory.
Simon stated that modeling how a bridge reacts to tension calls for modelling hundreds of countless numbers of component areas — and the physics of how those people parts interact when they are connected. “LINPACK is accomplishing this variety of fixing. And the accomplishment for LINPACK was you could remedy with the exact variety of computer software on extremely unique computers,” he stated.
Dongarra produced computer software to make it possible for computers to use multiple processors at the same time, and this is fundamentally how all laptop or computer techniques operate currently. Your notebook has numerous processing cores and may possibly have an additional graphics processing core. Quite a few telephones have multiple processing cores.
“He’s regularly rethought how to exploit today’s computer architectures and done so very successfully,” claimed Nicholas Higham a Royal Modern society analysis professor of used mathematics at the University of Manchester. “He’s arrive up with strategies so that we can get the incredibly best out of these machines.”
Dongarra also developed program that authorized personal computers with different components and functioning units to run in parallel, networking distant machines as a solitary computation gadget. This lets people today make much more potent computer systems out of several more compact units which helped establish cloud computing, running superior-close applications over the online.
Most of Dongarra’s work was published open-resource through a venture identified as Netlib.
“Jack is what I would phone a community builder,” Simon reported. “He was a person of the to start with to place people today collectively to share software program.”
As personal computers grew in scale, complexity and electricity, Dongarra’s work was instrumental for knowing what we were being creating. Dongarra created the Leading500 application deal, which steps the 500 quickest laptop or computer techniques on earth.
“It’s often very good to fully grasp how perfectly one thing is carrying out,” Dongarra stated. “So we produced metrics for executing that.”
At 71, Dongarra is “going emeritus,” as he calls it. He is retiring from instructing to emphasis on investigate. He’s centered on creating sure the University of Tennessee Revolutionary Computing Laboratory is in great palms.
He isn’t preparing on disappearing right after the award’s ceremony in June even though.
“I have an office environment and can proceed to work,” he mentioned. “So my strategy is to continue on with that.”
