Further Towards a Uni cation of

Traditionally, parallel programming paradigms are associated with only a single class of parallel architecture. No single model of parallel computation has been able to span the range of parallel architecture classes. This has resulted in a lack of portability of software between parallel architectures, also a lack of portability of programmers' skills. This report describes the latest developments and revisions of the author's work in unifying the basic parallel architecture classes. The original aim was to produce a single, uniied parallel architecture class. Each individual parallel architecture class has a parallel programming paradigm traditionally associated with itself. The uniied parallel architecture class would be capable of supporting all those parallel programming paradigms. However, the results of this uniication process demonstrate that all parallel architecture classes are capable of eeciently simulating the computation (control methods and memory access) of all other parallel architecture classes, while communication can not be simulated eeciently due to certain architecture classes being non-scalable in terms of bandwidth.
