Abstract
We present a new parallel computation model that enables the design of resource-optimal and scalable parallel algorithms and simplifies their analysis. The model rests on the following novel ideas : it incorporates optimality relative to a specific sequential algorithm as an integral part, and it measures the quality of a parallel algorithm in terms of granularity. Inspired by the BSP model, an algorithm in the PRO model is organized as a sequence of supersteps. The supersteps are not however required to be separated by synchronization barriers.
