Abstract
AbstractHigh Performance Fortran (HPF) is an emerging, de facto standard language for machine‐independent, data‐parallel programs that run on various parallel machines. The ease with which parallel programs can be created by means of simple data placement annotations to Fortran 90 programs is particularly attractive to end‐users. The success of the HPF approach, however, depends on the innovation in compiler technology. In order to achieve a reasonable speedup on the target parallel machine, the HPF compiler must be able to parallelize loops, optimize communications, localize arrays, and generate efficient, scalable single‐program multiple‐data (SPMD) code. We have implemented HPF on the basis of the IBM XL Fortran 90 compiler. This task will present an overview of our compilation strategy and preliminary results obtained on an IBM Scalable POWERparallel System.
