Precedence relationship performance of an indirect matrix solver

A highly parallel truncated accelerated Neuman series preconditioner is presented. Results from using this preconditioner are compared with those obtained using a traditional truncated Neumann series preconditioner and the Jacobi method on matrices whose numerical content is characteristic of the bus admittance matrices used in the analysis of faulted power system problems. These results show that the number of precedence relationships experienced by this technique are of the same order of magnitude as the number encountered when using direct methods
