Mathematical algorithms are crucial components of many scientific application codes used on high performance computers. They enable large scale simulations that can help to explore and better understand phenomena in physics, astronomy, chemistry, biology and more. Throughout my career I have worked on various exciting aspects of achieving good performance for mathematical software on ever evolving computer architectures with different features, increasing performance and memory capacities. Achieving good performance often requires significant changes to the software, including the design of new algorithms. It also requires collaboration between a variety of discipline experts. I will share some of the challenges and highlights throughout my career, as a computational mathematician, software developer at various institutions and a leader of a large project within the US Department of Energy’s Exascale Computing Project.

Ulrike Meier Yang – Lawrence Livermore National Laboratory
Ulrike Meier Yang leads the Mathematical Algorithms and Computing group in the Center for Applied Scientific Computing at Lawrence Livermore National Laboratory. Her research interests are numerical algorithms, particularly iterative linear system solvers and algebraic multigrid methods, high performance computing, parallel algorithms, performance evaluation and scientific software design.
Prior to joining LLNL in 1998, she was a staff member in the Center for Supercomputing Research and Development at the University of Illinois at Urbana-Champaign and the Research Centre Jülich, Germany. She earned her Ph.D. in Computer Science at the University of Illinois at Urbana-Champaign in 1995. She is a member of the SIAM Board of Trustees and has served on the editorial boards of SIAM Journal on Scientific Computing, SIAM Journal for Matrix Analysis and Applications and Journal of Parallel and Distributed Computing. She was named a SIAM Fellow in 2024.
