Dynamic data distributions in Vienna Fortran

Vienna Fortran is a machine-independent language extension of Fortran, which is based upon the Single-Program-Multiple-Data SPMD paradigm and allows the user to write programs for distributed-memory systems using global addresses. The language features focus mainly on the issue of distributing data across virtual processor structures. In this paper, we discuss those features of Vienna Fortran that allow the data distributions of arrays to change dynamically, depending on runtime conditions. We discuss the relevant language features, outline their implementation and describe how they may be used in applications.
