High-Level Data Parallel Programming in Promoter

Implementing realistic scientific applications on parallel platforms requires a high--level, problem--adequate and flexible programming environment. The hybrid system PRO- MOTER pursues a two--level approach allowing easy and flexible programming at both language and library levels. The core concept of PROMOTER's language model is its highly abstract and unified concept of data and communication structures. The paper briefly addresses the programming model, but focuses on implementation aspects of the compiler and runtime system. Finally, performance results are given, evaluating the efficiency of the PROMOTER system. 1. Introduction Despite of much research work in the area of parallel programming environments and compiler development that has been done over the past decade, the burden of parallel programming still lies in the automatic, transparent, and efficient treatment of locality. The problem arises, whenever one has to distinguish between (cheap) local and (expensive) remote..
