We investigate methods for creating highly portable par allel and distributed applications using the programming language C++. The paper elaborates on software engineer ing issues for efficiently mapping abstract class interfaces to system functionality -- typically designed by applying the wrapper facade design pattern -- on a large number of target platforms. We introduce a novel mapping tech nique which is based on generic programming. The pa per presents a detailed comparison of the proposed method with two other commonly applied techniques, concluding that our approach represents the most suitable technique for creating highly portable C++ programs in terms of effi ciency, ease of portability, and enforcement of correctness.
