An overview of the PTRAN analysis system for multiprocessing

View publication


PTRAN (Parallel TRANslator) is a system for automatically restructuring sequential FORTRAN programs for execution on parallel architectures. This paper describes PTRAN-A: the currently operational analysis phase of PTRAN. The analysis is both broad and deep, incorporating interprocedural information into dependence analysis. The system is organized around a persistent database of program and procedure information. PTRAN incorporates several new, fast algorithms in a pragmatic design. © 1988.
