China increasingly has the world’s most powerful supercomputers, while the United States continues its recent trend of decreasing prominence in development of such systems. That’s one takeaway from the latest TOP500 list, the forty-sixth such worldwide ranking of systems, led in part by UT’s Jack Dongarra.

Jack Dongarra, director of the Innovative Computing Laboratory, has been named to the Scientific and Engineering Advisory Committee for the Square Kilometer Array, a project to build a telescope with a total collection surface the size of one square kilometer.
UT computing expert Jack Dongarra was cited in a report detailing the need for faster computers.
The US Department of Energy recently released a report through its Office of Science detailing the top ten research challenges in reaching the level of exascale computing, once again calling on Jack Dongarra for input. Dongarra, a Distinguished Professor in the Department of Electrical Engineering and Computer Science, director of the Innovative Computing Laboratory and one of five National Academy of Engineering members at UT, has long been at the forefront of exascale computing, or computing at roughly a thousand times the capability of recent supercomputers.
The Department of Energy recently released a report co-chaired by UT Distinguished Professor Jack Dongarra in which he stresses the importance of prioritizing research into high-end mathematics to help keep the United States on the cutting edge of computing.
An internationally-recognized list launched by Jack Dongarra, distinguished professor of computer science, is receiving international coverage including the The Wall Street Journal‘s All Things D site. The latest edition of the TOP500 list which ranks the most powerful supercomputers is released this week, coinciding with a conference being held in Denver. According to the article.
Jack Dongarra, distinguished professor of computer science in the College of Engineering, is being honored for his leadership in high performance computing. He will receive the Association for Computing Machinery-Institute for Electrical and Electronics Engineers Computer Society Ken Kennedy Award on November 19 in Denver at SC13, the International Conference on High Performance Computing.
Data Center Knowledge featured the efforts of Distinguished Professor of Computer Science Jack Dongarra to revamp the performance metric used to rank the world’s top supercomputers. With so much emphasis and funding invested in the Top500 rankings, the 20-year old Linpack benchmark has come under scrutiny, with some in the community suggesting it needs to
Jack Dongarra, distinguished professor of computer science at UT is designing software that will be critical in making the next generation of supercomputers operational. For decades, supercomputers have been tackling the world’s most pressing challenges, from sequencing the human genome to predicting climate changes. But their power is limited and thus, so is our knowledge.
The way the power of supercomputers is measured is about to change. Since 1993, Jack Dongarra, distinguished professor of computer science at UT has led the ranking of the world’s top 500 supercomputers. The much-celebrated bi-annual TOP500 list is compiled using Dongarra’s benchmark system, called Linpack. But Dongarra says Linpack hasn’t kept pace with supercomputing needs and must be updated.
