Demmel is a professor of mathematics and computer science at the University of California, Berkeley. He is the founding chair of the graduate group in Computational Science and Engineering at UC Berkeley, which includes 117 participating faculty from 22 departments. Demmel also has a joint appointment as a member of the Future Technologies Group at Lawrence Berkeley National Laboratory.
He received the award "for computational science leadership in creating adaptive, innovative, high-performance linear algebra software." The award to Demmel brings to four the number of Fernbach Award recipients at Lawrence Berkeley National Laboratory. In addition to Demmel, other Berkeley Lab awardees are David Bailey (1993), Phillip Colella (1998), and John Bell (2005).
Involved in the design and development of algorithms and mathematical software for the past two decades, Demmel is known for his work on LAPACK and ScaLAPACK, which form the standard mathematical libraries for AMD, Apple (under Mac OS X), Cray, Fujitsu, Hitachi, HP, IBM, IMSL/Rogue Wave, Intel, InteractiveSupercomputing, several Linux distributions (including Debian), Mathworks (MATLAB), NAG, NEC, PGI, and SGI.
The software and standards Demmel developed enable users to transition their computer programs to new high-performance computers without having to re-implement the basic building blocks. The software is used by hundreds of sites worldwide, including all U.S. Department of Energy national laboratories, NASA research laboratories, many universities, and companies in the aerospace, automotive, chemical, computer, environmental, medical, oil, and pharmaceutical industries.
His parallel direct sparse linear equation solver SuperLU (with Xiaoye Sherry Li) was used to solve a quantum mechanical three-body scattering problem, leading to a 1999 cover article in Science magazine. His parallel unstructured 3D multigrid solver for finite element problems Prometheus (with Mark Adams) won the Carl Benz Award for the best industrial application at the Mannheim Supercomputer’99 Conference. His parallel eigensolver in ScaLAPACK (with Jack Dongarra and Ken Stanley) was runner-up in the Gordon Bell Peak Performance Prize at SC98.
Demmel is a fellow of IEEE, ACM, and SIAM, and a member of the National Academy of Engineering. He was the recipient of the J. H. Wilkinson Prize in Numerical Analysis and Scientific Computing in 1993, the SIAM SIAG on Linear Algebra Prize in 1988 and 1991, a Presidential Young Investigator Award in 1986, and an IBM Faculty Development Award in 1985, among others.
Established in 1992 in memory of high-performance computing pioneer Sidney Fernbach, the award recognizes outstanding contributions in the application of high-performance computers using innovative approaches. Set to be presented on November 17 at SC10, the award consists of a certificate and a $2,000 honorarium.
