DESIGN AND IMPLEMENTATION OF A FORTRAN ASSISTANT TOOL FOR VECTOR COMPILERS

In this paper, we present the design and implementation of a source-to -source High Performance Fortran assistant Tool (HPFT) in DEC 3000 wor kstations. For a given sequential program written in Fortran 77, the K PFT generates a vectorized, reuse-exploited and/or parallelized versio n for vector computers. Several new compilation schemes in vectorizati on, reuse exploitation and multithreading are designed in the HPFT. A performance evaluator is developed for measuring the system performanc e. The user interface is also designed for the programmer to capture t he information related to the compilation and execution of the program . Experimental results based on the Convex C3840 vector computer show that, the developed HPFT enhances the system performance and usually r educes the program execution time.
