LLNL’s Center for Applied Scientific Computing (CASC) serves as a window to the broader computer science, computational physics, applied mathematics, and data science research communities. A new video showcasing CASC’s computational mathematics research debuted at the International Council for Industrial and Applied Mathematics (ICIAM) conference in July. Among the featured projects are open source repos MFEM, a library of scalable finite-element discretization and solver algorithms, and XBraid, a library of parallel-in-time solvers.
