Nick Higham Interviewed in The Actuary Magazine

Professor Nick Higham is featured in the June 2020 issue of The Actuary Magazine, the magazine of the Institute and Faculty of Actuaries.

In an interview with the editor, Dan Georgescu, Nick talks about his development in 2002 of his nearest correlation matrix algorithm, which is widely used in finance and data science.

The magazine is freely readable on the Issuu platform.

More details about the nearest correlation matrix problem and algorithms for solving it are available on Nick’s blog.


Online Seminar Series on Numerical Linear Algebra

Dr Stefan Güttel is one of the organizers of a new online series of seminars on Numerical Linear Algebra. The talks are broadcast live on Zoom and YouTube every Wednesday at 4pm Central European Summer Time (CEST). The programme is available on the seminar website. At the time of writing, 942 people from 79 countries have signed up to the seminar mailing list.

The other organizers are Melina Freitag (University of Potsdam), Daniel Kressner (EPF Lausanne), Jörg Liesen (TU Berlin), Valeria Simoncini (University of Bologna), and Bart Vandereycken (University of Geneva).

The first talk in the series was given by Professor Nick Higham, titled Are Numerical Linear Algebra Algorithms Accurate at Extreme Scale and at Low Precisions? The slides for the talk are available at this link and the video is below.

Conference Celebrating the 70th Birthday of Jack Dongarra

by Sven Hammarling, Nick Higham, and Françoise Tisseur


Jack Dongarra

July 18, 2020 is the 70th birthday of Professor Jack Dongarra, who holds appointments at the University of Tennessee, Oak Ridge National Laboratory, and the University of Manchester.

Jack has made seminal contributions to algorithms for numerical linear algebra and the design and development of high performance mathematical software for machines ranging from workstations to the largest parallel computers. His recent honours include election as a Foreign Member of the Royal Society and receipt of the
SIAM/ACM Prize in Computational Science and Engineering (2019)and the IEEE Computer Society Computer Pioneer Award (2020).

To celebrate Jack’s birthday we are organizing a conference New Directions in Numerical Linear Algebra and High Performance Computing: Celebrating the 70th Birthday of Jack Dongarra at The University of Manchester, July 17, 2020.  Registration is now open and we welcome submission of posters.
