Geometric scheduling of 2-D uniform dependence loops

One of the primary tasks in the area of uniform dependence loops, is predicting the execution propagation, as well as finding an optimal time schedule. In this work, the problem of scheduling using wavefront prediction is presented. The geometric concepts of time instance subspaces and execution pattern are introduced. A quite simple and low complexity scheduling algorithm is presented. The index space is split into geometric subspaces and any point can be located in them. Each point is then scheduled according to the subspace where it belongs
