Minimum distance: a method for partitioning recurrences for multiprocessors

Parallel execution of nonvectorizable uniform recurrences is considered. When naively scheduled, such recurrences could create unacceptable communication and synchronization on a multiprocessor. The minimum-distance method partitions such recurrences into totally independent computations without increasing redundancy or perturbing numerical stability. The independent computations are well suited for execution on a multiprocessor, but they may not utilize all available processors. How extra processors can be applied to the independent computations is addressed. The methods are especially attractive for multiprocessors comprised of clusters
