July 1950 in Chicago) [first] [2] is an American mathematician and computer scientist who deals with numerical linear algebra, parallel arithmetic and algorithms and programming tools for high-performance computers and is considered an internationally leading expert in these areas. Dongarra is the son of Sicilian immigrants and the first in his family who went on the college. [3] As a child and adolescent, he suffered from undetected dyslexia, but it was fun to take machines apart and play with them. He studied at Chicago State University (Bachelor in Mathematics 1972), originally to become a math teacher, earning his studies through work in a pizzeria. [3] and the Illinois Institute of Technology (master’s degree in computer science 1973). In 1980 he received his doctorate in applied mathematics at the University of New Mexico at Cleve Barry Moler Improving the Accuracy of computed Matrix Eigenvalues ) [4] . From 1980 he was a senior scientist and from 1989 Distinguished Scientist of the Argonne National Laboratory. From 1989 he was a professor of computer science (from 1990 Distinguished Professor) at the University of Tennessee and Distinguished Scientist on the nearby OAK Ridge National Laboratory. He founded one there Innovative Computing Laboratory . He is also Adjunct Professor at Rice University and at its center for high -performance computers and was Turing Fellow at the University of Manchester. Dongarra wore, among other things, to the program packages ice pack, Linpack, Blas, Lapack, Scalapack, Netlib, parallel Virtual Machine (PVM), Message Passing Interface (MPI), Netsolve, Benchmarks of the TOP500, Automatic Autical Linear Albra Software (Atlas) and Performance Application Programming interface (dad). In 1972, he was involved in the ice pack (a program package, especially for self-esteem and self-vector calculation) (under Brian Smith). There, newer algorithms were implemented as the classic textbook algorithms, among other things developed by the Turing award winner James H. Wilkinson and Christian Reinsch. [3] When Ice pack was published in 1974, he was fully employed on the Argonne laboratory, but interrupted the work to do his doctorate and thus have better career opportunities. However, he worked there while working at the dissertation part -time on the implementation of algorithms on the Cray 1 supercomputer in the Los Alamos National Laboratory. After ice pack, he worked on Linpack, a program package for solving linear equations and the Method of the smallest squares, initiated by G. W. “Pete” Stewart, Clive Moler and Jim Bunch, who met regularly every year in the Argonne Laboratory. Dongarra should first design a test environment for the package, but soon rose to one of the main authors. Linpack became one of the most successful mathematical software packages of the 1980s and ran on almost all systems from supercomputer via workstations to PCs. The flexibility was based on the use of sub -routines for simple operations in the linear algebra, called Blas (Basic Linear Algebra Subprograms, originally introduced by Charles Lawson and Richard Hanson on the Jet Propulsion Laboratory of NASA), which was implemented here for the first time in a larger software project . For Linpack, Dongarra also introduced benchmark tests from the numerical linear algebra for high-performance computers, which are still used in the TOP500 project today. After Linpack, he developed with James Demmel Lapack, a library in which the software from Linpack and Ice pack (as well as blas) developed for the supercomputers (Cray-1, Cray-1, Cray-1), i.e. vectorrechner and parallel computers with a joint memory for a few parallel-calculating processors was optimized. The first publication was in 1992, followed by a further 1994 and 1999. Since not all manufacturers, the supported, he developed the Atlas project with his students [5] To implement blas for special computer architectures. With the further development of the hardware into massive parallel computers and clusters of processors, Dongarra also devoted himself to the adaptation of the software for numerical linear algebra to these architectures with distributed memory (scalapack, published for Scalable Lapack, 1993). They used PVM (parallel virtual machine), which also found spread in other projects. He was also involved in the development of the Message Passing Interface (MPI), which was standardized in 1994. With further hardware development to higher performance, especially for graphic applications in the 2010s, with supercomputers used in parallel thousands of high-performance graphics chips, he proposed a new approach in 2016. [6] For this purpose, invoices with large matrices were automatically broken down into smaller blocks (implemented in the libraries Magma and Slate and in batched blas standard). In 2006 he suggested how to combine sliding comma calculations based on (more precise) 64-bit numbers with the faster based on 32-bit numbers in order to draw advantages from both representations and optimize the calculation speed. [7] The method quickly prevailed, for example, when learning machine. In the mid -1980s, he founded Gro\u00dfen Golub and Eric Great during a stay at Stanford University Netlib, [8] With the motivation to collect software that developed doctoral students and others during their work and make them accessible to others via email. When Dongarra and Gro\u00dfen were at the Bell Laboratories in 1985, they put the idea into practice, both of which met the selection of the software. Later, existing collections such as that of the ACM magazine Transactions on Mathematical Software integrated. Developed by Dongarra or code collected in his libraries found its way into commercial mathematical software packages such as Mathematica, Matlab, Maple or the R programming language. He has been editor of the International Journal of High Performance Computing Applications and founder of the supercomputing interest group at SIAM. He is Fellow of the Ieee, the Association for Computing Machinery, the American Association for the Advancement of Science, the National Academy of Engineering and the Royal Society. In 2016 he was elected foreign member of the Russian Academy of Sciences. [9] In 2003 he received the Sidney Fernbach Award, 2020 the computer Pioneer Award. He also received the Siam\/ACM Prize in Computational Science and Engineering and the ACM\/IEEE KEN Kennedy Award. For 2021, Dongarra was awarded the Turing Award, one of the highest awards in the field of computer science, [ten] [3] for His pioneering contributions to numerical algorithms and libraries, which made it possible to keep up high-performance software for four decades with the exponential development of the hardware (Laudatio, For his pioneering contributions to numerical algorithms and libraries that enabled high performance computational software to keep pace with exponential hardware improvements for over four decades ). He has been married to Susan Sauer since 1980. The couple has three children.
