Abstract
Fortran D is a version of Fortran enhanced with data decomposition specifications. Case studies illustrate strengths and weaknesses of the prototype Fortran D comprier when compiling hnear algebra codes and whole programs. Statement groups, execution conditions, inter-loop communication optimizations, multi-reductions, and array kills for rephcated arrays are identified as new compilation issues. On the Intel iPSC/860, the output of the proto- type Fortran D compiler approaches the performance of hand-optimized code for parallel computations, but needs improvement for hnear algebra and pipehned codes. The Fortran D compiler outperforms the CM Fortran compiler (2.1 beta) by a factor of four or more on the TMC CM-5 when not using vector units. Better analysis, run-time support, and flexibility are required for the prototype compiler to be useful for a wider range of programs.
