The data parallelism under java paralleltask: A simple and efficient approach

With the advent of multicore general public systems, a new perspective of parallel processing is available to application developers. Adapting old sequential applications to performance of parallel systems proves imperative. The Task Parallel Java compiler (ParaTask) is a solution for the development of object-oriented parallel applications, based on the concept of different types of tasks. It is easily exploitable for the change (refactoring) of existing sequential applications by using simple keywords. Parallelism is introduced either in the form of parallel data and parallel task, or as a mixed parallel / Data tasks. It comes to performed in this work, the parallelization of the sequential algorithm of Canny contour detection on images of different sizes.
