Object-Oriented Parallelisation: Improved and Extended Parallel Iterator

The need to parallelise desktop applications is becom-ing increasingly essential with the mainstream adoption of multi-cores. In object-oriented languages, sequential itera-tors handle iterative computations of a sequential program; similarly, the parallel iterator was developed to handle the iterative computations of a parallel program. This paper presents the progress of the parallel iterator concept. New features, such as support for reductions and global break semantics, allow the parallel iterator to undertake more sit-uations. With a slight contract modification, the parallel iterator interface now imitates that of the sequential itera-tor. All these features combine together to promote minimal, if any, code restructuring. The reduction frequently outper-forms related work and the importance of providing simple and flexible fine-tuning capability is affirmed
