Abstract

Software development for the next generation of high-performance computers is faced with a challenge-how to exploit applications parallelism without rewriting and redesigning current sequential programs and algorithms from scratch. A prototype tool for interactive parallelization of Fortran, called PAT, is described. The current versions of Pat support Fortran 77, together with Cray micro- and macrotasking, IBM Parallel Fortran, and Sequent Parallel Fortran constructs for parallelism. Pat is implemented using the C language and has been ported to a range of Unix systems, using X-windows for their graphics interface. The internal representation and I/O of multitasking primitives have been carefully designed and implemented to be easily ported to different multitasking dialects.<>
