Tennessee’s Jack Dongarra wins prestigious A.M. Turing Award
A nearby computer system scientist and professor at the University of Tennessee at Knoxville has been named an A.M. Turing Award winner by the Affiliation for Computing Machinery.
The Turing Award is often referred to as the “Nobel Prize of pc science.” It carries a million greenback prize.
“Oh, it was a finish shock. I’m nevertheless recovering from it,” Jack Dongarra told Knox News with a heat giggle. “It’s pleasant to see the perform staying recognized in this way but it couldn’t have transpired devoid of the aid and contribution of lots of persons in excess of time.”
Probabilities are Dongarra’s operate has touched your life, even if you don’t know it. If you have ever made use of a speech recognition method or seemed at a temperature forecast, you are employing engineering that relies on Dongarra’s software libraries.

Dongarra has held a joint appointment at the University of Tennessee and Oak Ridge National Laboratory since 1989. Though he doesn’t have a household title, his foundational function in computer system science has undergirded the enhancement of higher-performance desktops above the training course of his 40-12 months profession.
“I want to turn into a job product as numerous of the other recipients have been for the up coming technology of personal computer scientist,” Dongarra said.
If you have a multicore computer (and you possibly do because everything is multicore now) or use a graphics card, you are relying on Dongarra’s code. The macOS and iOS running program, scientific simulations and mathematical software package like MatLab or Maple all depend on versions of Dongarra’s software package libraries.
“Jack Dongarra’s contributions to software package deals and libraries have been seminal in driving development and developments in laptop or computer science and innovation in a spectrum of purposes,” explained Thomas Zacharia, director of Oak Ridge Nationwide Laboratory. “Whether it’s vitality protection, national security … at the core are his standard contributions in applied mathematics.”
In the late 1970s, Dongarra was a researcher at Argonne National Laboratory in the vicinity of Chicago. He experienced just made the decision to go into computer system science entire-time right after contemplating a job as a trainer. Whilst there, Dongarra served create an open up-supply program library termed LINPACK.
LINPACK permitted the supercomputers of the day to solve linear algebraic challenges with high effectiveness. That is important for the reason that computer systems are essentially enormous calculators. As the calculations get much more sophisticated, it’s very crucial that desktops can retail store and crunch numbers rapidly and precisely.
“When you search at deciding which path to decide on with your GPS, there is this aspect of info processing,” explained Michela Taufer, a professor of pc science at the College of Tennessee at Knoxville. “The important, atomic component of automated conclusion earning are vectors and matrixes. Those operations are finished by linear algebra.”
Linear algebra computer software libraries like LINPACK authorized experts to operate several calculations concurrently. Then, they can operate simulations of all the things from weather conditions devices to nuclear meltdowns.
“If you’re fixing an engineering difficulty, you could have equations with hundreds of 1000’s of details points,” said Horst Simon, former deputy director of the Lawrence Berkley Countrywide Laboratory.
Simon explained that modeling how a bridge reacts to worry involves modelling hundreds of countless numbers of component elements — and the physics of how individuals items interact when they are connected. “LINPACK is performing this type of fixing. And the accomplishment for LINPACK was you could solve with the similar kind of software program on very diverse personal computers,” he said.

Dongarra developed software to allow for personal computers to use multiple processors concurrently, and this is generally how all computer methods work right now. Your laptop computer has multiple processing cores and might have an further graphics processing main. Quite a few phones have several processing cores.
“He’s constantly rethought how to exploit today’s laptop architectures and performed so incredibly effectively,” explained Nicholas Higham a Royal Modern society investigate professor of applied mathematics at the University of Manchester. “He’s come up with ideas so that we can get the extremely greatest out of these machines.”
Dongarra also designed software package that allowed computer systems with diverse hardware and working programs to operate in parallel, networking distant machines as a single computation device. This lets folks make extra strong computers out of lots of scaled-down gadgets which helped acquire cloud computing, operating superior-conclude programs more than the internet.
Most of Dongarra’s perform was published open up-resource through a task named Netlib.
“Jack is what I would simply call a group builder,” Simon mentioned. “He was a single of the 1st to place people together to share program.”
As desktops grew in scale, complexity and ability, Dongarra’s perform was instrumental for comprehension what we had been creating. Dongarra developed the Top rated500 computer software package, which steps the 500 speediest computer system methods on earth.
“It’s constantly fantastic to realize how very well a little something is accomplishing,” Dongarra reported. “So we formulated metrics for performing that.”
At 71, Dongarra is “going emeritus,” as he calls it. He is retiring from instructing to target on investigation. He’s centered on producing positive the College of Tennessee Progressive Computing Laboratory is in superior palms.
He isn’t arranging on disappearing following the award’s ceremony in June while.
“I have an business office and can proceed to function,” he said. “So my strategy is to continue on with that.”
