SPEAKER/BIO:
*Dr. Ann Almgren, Senior Scientist, Computational Research Division/
Applied Mathematics, Lawrence Berkeley National Lab*


ABSTRACT:

Adaptive mesh refinement (AMR) is a technique we use as a numerical
microscope to zoom in on areas of interest in a computer simulation. With
more resolution we get more accurate answers and can see in more detail
what is happening in the simulation. In this talk I will describe in
general terms how AMR works and how we use it effectively on today's
supercomputers, and I will present examples from a wide range of
applications.

Bio: Ann Almgren is a senior scientist in the Computational Research
Division of Lawrence Berkeley National Laboratory and the Group Lead of the
Center for Computational Sciences and Engineering. Her primary research
interest is in computational algorithms for solving partial differential
equations in a variety of application areas. Her current projects include
the development and implementation of new multiphysics algorithms in
high-resolution adaptive mesh codes that are designed for the latest hybrid
architectures. She is a SIAM Fellow and the Deputy Director of the Exascale
Computing Program's AMReX Co-Design Center, serves on the editorial boards
of CAMCoS and IJHPCA, and co-leads LBL's Computing Sciences Area Mentoring
Program.
