Towards a Uniied Parallel Architecture Class

Traditionally, parallel programming paradigms are associated with only a single class of parallel architecture. 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 author's work in unifying the basic parallel architecture classes with the aim of producing a single, uniied parallel architecture class. Such a uniied class would be capable of supporting all the parallel programming paradigms traditionally associated with the individual parallel architecture classes uniied to form the single parallel architecture class. 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, communication can not be so simulated eeciently due to certain architecture classes being non-scalable in terms of bandwidth.
