Abstract :
The need to parallelise desktop applications is becoming increasingly essential with the mainstream adoption of multi-cores. In object-oriented languages, sequential iterators 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 situations. With a slight contract modification, the parallel iterator interface now imitates that of the sequential iterator. All these features combine together to promote minimal, if any, code restructuring. The reduction frequently outperforms related work and the importance of providing simple and flexible fine-tuning capability is affirmed.
