| Research Abstract |
Temporal-Spatial (TS) tiling proposed in this research is an optimization technique to improve the memory access locality in a TS-nested loop, adopted in most of simulation codes as their fundamental structure, by splitting the spatial loop into a set of those for smaller spaces (tiles) fitting to cache memory and by iterating updates on each tile for multiple time steps. In this research, we developed a framework of automatic application of TS tiling based on local-view fragmental coding, and then applied TS tiling to applications including FDTD electromagnetic field analysis, PIC plasma simulation, and multi-grid Poisson solver, to confirm each application is accelerated by factor two as we aimed at.
