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.
SAMRAI v. 2.13.0 is now available! The major change is that we no longer use the Boost library. This affects many interfaces in the API that used boost::shared_ptr, which has been replaced by std::shared_ptr.
SAMRAI is an open source project, and questions, discussion and contributions are welcome!
To get in touch with all the SAMRAI developers, please email samrai@llnl.gov
Contributing to SAMRAI should be easy! We are managing contributions through
pull requents here on GitHub. When you create your pull request, please make
develop the target branch.
Your PR must pass all of SAMRAI's unit tests, which are enforced using Travis CI. For information on how to run these tests locally, please see our contribution guidelines
Our development process roughly follows the
gitflow model. The
master branch points to the last stable, tagged release. The develop branch
contains the latest changes. New features should be created in feature/<name>
branches and be based on develop.
We maintain a list of publications here.
