He had not been well for some time and suffered from chronic obstructive pulmonary disease. Following school at Wheelwright Grammar School in Dewsbury (its alumni also included Leslie Fox and Tom Kilburn), Donald obtained his first degree at University College Hull, an outpost of London University, and his PhD from the University of Edinburgh. His scientific work included computer coding, QD algorithms, linear algebra, special function theory, approximation theory, quadrature, and integral equations and their applications. A detailed account of Donald's career would incorporate his contributions in the histories of the Admiralty Research Laboratory (Teddington), of the Computer Unit at Edinburgh University, in Scottish Numerical Analysis (including the history of the Dundee NA meetings) and of numerical analysis and approximation at Lancaster University as well as meetings held at the Mathematisches Forschungsinstitut Oberwolfach, the London Mathematical Society Durham Symposia, and SERC conferences at Lancaster University - these stories liberally sprinkled with the names of many of the contemporary pioneers in the mathematical sciences and Donald's "mathematical descendants'. He loved Italy, enjoying visits to Turin and teaching summer schools at Perugia. A singularly able yet modest and unassuming mathematician, Donald was a steadfast friend and will be sadly missed. His hobbies had included campanology and woodwork and he had a great love of music. He is survived by his wife Carol, his sons Samuel and Edward, and grandchildren Rebecca, Thomas, James and Harry.

LAFF is an introductory course on linear algebra that links abstractions in mathematics to abstractions in code. The course targets many audiences, ranging from novices to those wanting a refresher. The course heavily stresses partitioning of matrices and vectors and uses our "FLAME notation" to present algorithms. Later this Spring, we will offer a related course "LAFF-On Programming for Correctness" (LAFF-On) that builds upon the FLAME notation to demonstrate how programs can be systematically derived to be correct. More details on this new course will be given in a future posting to NA Digest. To register for LAFF, visit edx.org and search for "LAFF". ------------------------------------------------------- From: Michael Bader [log in to unmask] Date: January 03, 2017 Subject: HPC in Atmosphere Modelling/Air Related Hazards, Czech Republic, Feb 2017 The Czech-Bavarian Competence Team for Supercomputing Applications invites all interested researchers to a workshop on "High performance computing in atmosphere modelling and air related environmental hazards". The workshop takes place at IT4Innovations, Ostrava, Czech Republic, on February 9-10, 2017. Contributed presentations are welcome on all related topics, in particular on demands and desired features of (future) simulation software, parallelisation for current and novel HPC platforms, as well as establishing scalable simulation workflows on supercomputing environments. Details can be found under http://prace.it4i.cz/en/high-performance-computing-in-atmosphere-modelling-and-air-related-environmental-hazards If you wish to give a presentation, please submit a title and short abstract (10-20 lines) via email to Michael Bader .

[log in to unmask] Date: January 02, 2017 Subject: Lattice Boltzmann Methods with OpenLB Software Lab, Tunisia, Mar 2017 Registration is prolonged for the spring school Lattice Boltzmann Methods with OpenLB Software Lab that will be held in Hammamet, Tunisia, from 6. to 10. March 2017. The spring school introduces scientists and applicants from industry to the theory of LBM and trains them on practical problems. The first three days are dedicated to the theoretical fundamentals of LBM up to ongoing research on selected topics. Followed by two days of mentored training on case studies using OpenLB, the participants gain deep inside into LBM and its applications. This educational concept is probably unique in the LBM community and offers a comprehensive and personal guided approach to LBM. Participants also benefit from the knowledge exchange during poster session, coffee breaks and the excursion at the Mediterranean sea. We look forward to your participation.

The Finite Elements in Flow (FEF) Problems Conference has a rich history that closely parallels the development and maturation of the finite element method and its application to computational fluid dynamics problems. The FEF meetings began in Swansea (U.K.) in 1972 and are the principal forum for the exchange of research results in all aspects of flow simulation using the finite element method. The scope of the conference is intentionally broad with coverage of theory, implementation, assessment and application in all of the major and emerging areas of fluid dynamics and flow-related phenomena.

The aim of this conference is to bring together researchers working on aspects of nonlinear phenomena and to encourage interaction between experts from different areas such as Applied Mathematics, Mathematical Analysis, Fluid Dynamics, Engineering and Physics. Recent theoretical developments, new computational methods and experimental findings will be presented and discussed. We plan to avoid parallel sessions and foster as much as possible communication across the different communities. Conference topics: Integrable systems; Nonlinear waves in fluids; Soliton theory; Nonlinear evolution PDEs; Orthogonal polynomials; Mathematical biology; Coherent structures in shear flows and transition to turbulence. Papers will be accepted for the conference based on a 200 word abstract on any of the above topics for oral or poster presentation. Abstracts should be submitted by Friday 24 February via https://my.ima.org.uk/. Please state whether your title is intended for oral or poster presentation.
