SAMRAI Overview

The Center for Applied Scientific Computing (CASC) at Lawrence Livermore National Laboratory is developing algorithms and software technology to enable the application of structured adaptive mesh refinement (SAMR) to large-scale multi-physics problems relevant to U.S. Department of Energy programs.

The SAMRAI (Structured Adaptive Mesh Refinement Application Infrastructure) library is the code base in CASC for exploring application, numerical, parallel computing, and software issues associated with SAMR. SAMRAI development has been funded primarily by the DOE Advanced Simulation and Computing (ASC) Program. This investment is complemented by collaborative efforts supported by the Laboratory-Directed Research and Development (LDRD) program.
