SAMRAI

SAMRAI (Structured Adaptive Mesh Refinement Application Infrastructure) is an object-oriented C++ software library that enables exploration of numerical, algorithmic, parallel computing, and software issues associated with applying structured adaptive mesh refinement (SAMR) technology in large-scale parallel application development. SAMRAI provides software tools for developing SAMR applications that involve coupled physics models, sophisticated numerical solution methods, and which require high-performance parallel computing hardware. SAMRAI enables integration of SAMR technology into existing codes and simplifies the exploration of SAMR methods in new application domains.

New Release

The current release is SAMRAI v. 4.0.1. With the version 4 release, the SAMRAI project is pleased to introduce new features that support running applications on GPU-based architectures, using capabilities provided by the Umpire and RAJA libraries.
