Compiling Fortran 77 D and 90 D forMIMD Distributed-Memory

We present an integrated approach to compiling For-tran 77D and Fortran 90D programs for eecient execution on MIMD distributed-memory machines. The integrated Fortran D compiler relies on two key observations. First, array constructs may be scalarized into forall loops without loss of information. Second, loop fusion, partitioning, and sectioning optimizations are essential for both For-tran D dialects.
