Abstract
A method for allocating an arbitrary spatial load in two or three dimensions to an arbitrary number of parallel processing elements. The method produces as output spatial boundaries for each processor, which can then be used to redistribute the parallel computing load. Unlike existing techniques, this method allows the load to be characterized in communication time proportional to the number of dimensions and memory proportional to the number of processors in parallel. Further, this method takes as input an arbitrary number of processors, as well as an arbitrary weight for each processor, and allocates a load proportional to the processor weight to each. As a result, computing loads can be efficiently allocated to the processing elements to maximize speedup due to parallelization.
