Efficiency of map functions for different methods and mapping. Percentages of compute and idle time in map function for coarse- vs. fine-grained mapping and centered vs. optimized methods, i.e., (a) Coarse-grained mapping using centered method; (b) Coarse-grained mapping using optimized method; (c) Fine-grained mapping using centered method; and (d) Fine-grained mapping using optimized method.
