Towards a parallel framework of grid-based numerical algorithms on DAGs

This paper presents a parallel framework of grid-based numerical algorithms where data dependencies between grid zones can be modeled by a directed acyclic graph (DAG). It consists of three parts on how to partition, order and calculate the vertices of digraph. Numerical results using hundreds of processors on two parallel machines show the efficiencies and moderate scalability of this framework.
