In this paper, two programming tools are presented, facilitating the development of portable parallel applications on distributed memory systems. The Orchid system is a software platform, i.e. a set of facilities for parallel programming. It consists of mechanisms for transparent message passing and a set of primitive functions to support the distributed shared memory programming model. In order to free the user from the tedius task of parallel programming, a new environment for logic programming is introduced: the Daffodil framework. Daffodil, implemented on top of Orchid, evaluates pure PROLOG programs exploiting the inherent AND/OR parallelism. Both systems have been implemented and evaluated on various platforms, since the layered structure of Orchid ensures portability only by re-engineering a small part of the code.
