Compiling High Performance Fortran to Message Passing

ADAPTOR is a public domain High Performance Fortran compilation system that provides the comfortable data parallel programming paradigm on parallel machines with distributed memory. Therefore, the data parallel programs with their global view of data are translated to programs that work on the local parts of the distributed data and exchange the other needed data via message passing. This paper describes the design and the implementation of the ADAPTOR system and discusses its portability by using a portable messagepassing interface. The advantages of using the new message passing interface MPI are outlined. Furthermore, the combination of data parallel programs with efficient message passage programs is discussed that will allow the use of existing libraries.
