Object oriented parallel programming: experiments and results

We present an object-oriented, parallel programming paradigm, called the distributed collection model and an experimental language PC++ based on the model. In the distributed collection model, programmers can describe the data distribution of elements among processors to utilize memory locality and a collection construct is employed to build distributed structures. The model also supports the express of massive parallelism and a new mechanism for building hierarchies of abstractions. Our experiences with application programs in the PC++ programming environments as well as performance results are also described in the paper.
