Automated transformation of fortran programs essential for their efficient parallelization through Sapfor system

Automatic mapping of sequential programs on height performance computers with distributed memory may require preliminary transformation of programs oriented to this class of systems. Using the SAPFOR system for parallelization of applications allowed to explore transformations which can be executed in an automated way. The paper presents transformations that increase the possibility of efficient parallelization of programs by eliminating the reasons that prohibit the parallel execution of loops. Implementation of these transformations allowed to automate the obtainment of serial hydrodynamic program, which may be efficiently mapped on modern clusters by the automatically parallelizing compiler included in the SAPFOR.
