Description:  SFCGen: A framework for efficient generation of multidimensional spacefilling curves by recursion. Because they are continuous and selfsimilar, spacefilling curves have been widely used in mathematics to transform multidimensional problems into onedimensional forms. For scientific applications, reordering computation by certain spacefilling curves can significantly improve data reuse because of the locality properties of these curves. However, when spacefilling curves are used in programs for reordering data, traversal or indexing of the curves must be efficient.par To address this problem, we present the tabledriven framework SFCGen to efficiently generate multidimensional spacefilling curves on the fly. The framework is general and easy enough to be used in any application that can be partitioned recursively in multiple dimensions. We describe a movement specification table, a universal turtle algorithm to enumerate points along a spacefilling curve, a tablebased indexing algorithm to transform coordinates of a point into its position along the curve and an algorithm to pregenerate the table automatically.par As examples, we show how highdimensional Hilbert, Morton, and Peano curves and a twodimensional Sierpiński curve can be generated with our algorithms. We present performance results for Hilbert, Morton, and Peano curves and compare the efficiency of our curve generation algorithm with the most recent work on generating Hilbert curves. Our experimental results on three modern microprocessorbased platforms show that SFCGen performs up to 63
