Vienna Fortran: A Fortran Language Extension for Distributed MemoryMultiprocessors

摘要

Exploiting the performance potential of distributed memory machines requires acareful distribution of data across the processors. Vienna Fortran is a language extension of Fortran which provides the user with a wide range of facilities for such mapping of data structures. However, programs in Vienna Fortran are written using global data references. Thus, the user has the advantages of a shared memory programming paradigm while explicitly controlling the placement of data. In this paper, we present the basic features of Vienna Fortran along with a set of examples illustrating the use of these features.
