Description
Cactus is an open source problem solving environment designed for
scientists and engineers. Its modular structure easily enables
parallel computation across different architectures and
collaborative code development between different groups. Cactus
originated in the academic research community, where it was
developed and used over many years by a large international
collaboration of physicists and computational scientists.
