Titel
A schedule cache for data parallel unstructured computations
Abstract
High Performance Fortran (HPF) is the de facto standard language for writing data parallel programs. This study describes a dynamic approach for optimizing unstructured communication in codes with indirect addressing. The basic idea is that the run-time data reflecting the communication patterns will be reused if possible. The user has only to specify which data in the program have to be traced for modifications. The experiments and results show the effectiveness of the chosen approach.
