The Society for Industrial and Applied Mathematics (SIAM) and Association for Computing Machinery (ACM) announced that they have awarded the 2023 SIAM/ACM Prize in Computational Science and Engineering to the team behind the LLNL-developed SUNDIALS software suite. The prestigious award is handed out every two years and recognizes outstanding contributions to the development and use of mathematical and computational tools and methods for the solution of science and engineering problems. It is one of SIAM’s most significant awards and will be presented to the team at the 2023 SIAM Conference on Computational Science and Engineering in Amsterdam next February. Because of its ease, flexibility and extensive documentation, SUNDIALS has become internationally recognized as one of the most effective and efficient time integration libraries. It is widely used by government laboratories and in academic institutions and industry, leading to advances in a variety of applications including fusion device modeling, watershed modeling, and reacting flow simulations.

Team members are Distinguished Member of the Technical Staff Carol Woodward, computational scientists Cody Balos and David Gardner, senior scientist Peter Brown, LLNL guest scholar and retiree Alan Hindmarsh, former LLNL postdoc Daniel Reynolds, and former LLNL scientist Radu Serban.
