The Manchester Numerical Linear Algebra Group (many of whom are in the October 2017 photo below) was involved in a variety of activities this year. This post summarizes what we got up to. Publications are not included here, but many of them can be found on MIMS EPrints under the category Numerical Analysis.
Together with Jack Dongarra’s team at the University of Tennessee the group is one of the two partners involved in the development of PLASMA: Parallel Linear Algebra Software for Multicore Architectures.
We continue to make our research codes available, which is increasingly done on GitHub; see the repositories of Fasi, Higham, Relton, Sego, Tisseur, Zhang. We also put MATLAB software on MATLAB Central File Exchange and on our own web sites, e.g., the Rational Krylov Toolbox (RKToolbox).
Postdoctoral Research Associates (PDRAs)
Sam Relton, who was working on the Parallel Numerical Linear Algebra for Extreme Scale Systems (NLAFET) project, left in June 2017 to take up a position at the University of Leeds. Negin Bagherpour joined NLAFET in March 2017, leaving in November 2017.

Recognition and Service
Stefan Güttel continued his terms as Secretary/Treasurer of the SIAM UKIE section and vice-chair of the GAMM Activity Group on Applied and Numerical Linear Algebra.
Nick Higham served the first year of his two-year term as President of SIAM.
Weijian Zhang was awarded a SIAM Student Travel Award to attend the SIAM Annual Meeting 2017 in Pittsburgh.
Massimiliano Fasi and Mante Zemaityte were selected to present posters at the SET for Britain 2017 competition, which took place at the House of Commons, London.
