(Pete) Stewart Gilbert Wright Stewart III (1940-2026) I am very sorry to report that G. W. (Pete) Stewart died on June 9, age 85. Pete was a long-time faculty member in Computer Science (1974-2008), AMSC, IPST, and UMIACS at the University of Maryland. Locally, he is remembered for broadcasting classical music throughout the neighborhood of his office and for wandering the hallways in somewhat of a trance whenever he was designing code or a proof. He also made the rounds regularly, with coffee in hand, visiting colleagues throughout the department. Pete was a meticulous scientist, famous for deep results in computational linear algebra, finely-tuned code (e.g., in LINPACK), and exquisitely clear writing. It is widely accepted that he was the first successor to James Wilkinson, the first giant in the field, advancing the perturbation theory research that Wilkinson so ably began and complementing it with algorithmic innovation. Pete was a Distinguished University Professor Emeritus. He was selected as a SIAM Fellow "for contributions to numerical linear algebra," and as a member of the National Academy of Engineering "for the development of numerical algorithms and software widely used in engineering computation". Other honors include reception of the F.L. Bauer Prize. Pete authored 8 books and over 170 articles. I treasured him as a colleague. It was an incredible experience to see how his mind worked as we puzzled out the next step in joint projects. His wife, Astrid Schmidt-Nielsen survives him, as do his children Michael and Laura and step-children Mimi and Tom. ------------------------------------------------------- From: David Bindel bindel@cornell.edu Date: June 07, 2026 Subject: Richard Tapia Richard Tapia passed away at the age of 88 on May 22. He was a much decorated computer scientist and mathematician, a numerical analyst devoted to nonlinear optimization problems. He was also a dedicated advocate for increasing the participation of minorities in science and engineering. Tapia spent his career at Rice University, and they have posted a moving memorial article: https://news.rice.edu/news/2026/richard-tapia-pioneering-mathematician-and-advocate-diversity-passes-away-88 There is also an article on his career in the Communications of the ACM: https://cacm.acm.org/news/in-memoriam-richard-a-tapia-1939-2026/ ------------------------------------------------------- From: FERNANDO DE TERAN fteran@math.uc3m.es Date: June 11, 2026 Subject: Announcement for Topical Activity Group E-ANLAMA of the EMS The Topical Activity Group (TAG) E-ANLAMA (Applied and Numerical Linear Algebra, Matrix Analysis and Applications) is one of the active TAGs of the European Mathematical Society. The aim of the TAG is to bring together European scientists, and to foster the connections between researchers all over the world, working on numerical and applied linear algebra, matrix analysis and their applications. More information on the TAG, including a list of past and future endorsed activities, can be found at the website of the TAG: https://sites.google.com/view/ems-tag-anlama If you are interested in becoming a member of the TAG, please send an email to Emre Mengi emengi@ku.edu.tr. No fees are required. By becoming a member of the TAG you will be added to the mailing list and receive the announcements on future activities. Everybody is welcome to join. ------------------------------------------------------- From: Daniel B Szyld szyld@temple.edu Date: June 10, 2026 Subject: Report on symposium for Stratis Gallopoulos' retirement, 4-5 June 2026 Report on the Symposium on Matrix Methods and Scientific Computing, in honor of Prof. E. Gallopoulos, on the occasion of his retirement, 4-5 June 2026, University of Patras, Greece https://www.ceid.upatras.gr/assets/2026/05/SymposiumBrochure-1.pdf We had a very nice two-day affair, with a mix of technical talks and tributes including those from Erricos Kontoghiorghes, Yousef Saad, Valeria Simoncini (Stratis Gallopoulos' first PhD student), Tasos Zousias, and a dozen other former students, as well as an array of Patras and Greek authorities. Kudos for Costas Bekas and Andreas Stathopoulos who put together such a wonderful event! ------------------------------------------------------- From: Roger Ghanem ghanem@usc.edu Date: June 09, 2026 Subject: UQ Summer School, Los Angeles, Aug 12-14 2026 The UQ Summer School will be held again on the Campus of USC in Los Angeles, from August 12-14 2026.

This is a teaching and research position equivalent to Assistant Professor. High-Performance Computing is interpreted broadly and includes design of algorithms and software for mixed-precision numerical linear algebra, theory of computer number systems and arithmetic, development of hardware for numerical computation, and design of number formats and computer arithmetic for machine learning.
