Construction of large-scale simulation codes using ALPAL (A Livermore Physics Applications Language)

Description: A Livermore Physics Applications Language (ALPAL) is a new computer tool that is designed to leverage the abilities and creativity of computational scientist. Some of the ways that ALPAL provides this leverage are: first, it eliminates many sources of errors; second, it permits building code modules with far greater speed than is otherwise possible; third, it provides a means of specifying almost any numerical algorithm; and fourth, it is a language that is close to a journal-style presentation… more
