We study structure prediction for computations that involve nonsymmetric row and column permutations and nonsymmetric or non-square matrices. Our tools are bipartite graphs, matchings, and alternating paths..Our main new result concerns . factorization with partial pivoting. We

The number of factors in the partitioned inverse is proportional to the number of general communication steps (router steps on a CM-2) required in a highly parallel a

Parallel graph heuristics, convergence analysis, and basic linear algebra implementation issues must all be considered..In this paper, we discuss how we have incorporated these results into a general-purpose iterative solver. We present two recently d
